Figure 2-2 System configuration of three-phase 220 V/380 V voltage class, 2.2 Kw and above 2.4.1 Description of Peripheral Electrical Devices Table 2-2 Description of peripheral electrical devices Part Mounting Location MCCB Power receiving side Contactor Between MCCB and AC drive input side AC input reactor AC drive input side Function Description Interrupt the power supply when overcurrent occurs on down stream devices Start and stop the AC drive. Do not start and stop the AC drive frequently by switching the contactor on and off (less than twice per minute) nor use it to directly start the AC drive. • Improve the power factor of the input side. • Eliminate the higher harmonics of the input side effectively and prevent other devices from being damaged due to distortion of the voltage waveform. • Eliminate the input current unbalance due to unbalance between the power phases. www.ssinverter.info SSI700 User Manual Part Product Information Mounting Location EMC Input filter AC drive input side AC output reactor Between AC drive output side and the motor, close to the AC drive Function Description • Reduce the external conduction and radiation interference of the AC drive. • Decrease the conduction interference flowing from the power end to the AC drive and improve the anti interference capacity of the AC drive. The output side of the AC drive generally has much higher harmonics. When the motor is far from the AC drive, there is much distributed capacitance in the circuit and certain harmonics may cause resonance in the circuit, bringing about the following two impacts: • Degrade the motor insulation performance and damage the motor in the long run. • Generate large leakage current and cause frequent AC drive protection trips. If the distance between the AC drive and the motor is greater than 50 m, install an AC output reactor. 1) Do not install the capacitor or surge suppressor on the output side of the AC drive. Otherwise, it may cause faults to the AC drive or damage to the capacitor and surge suppressor. 2) Inputs/Outputs (main circuit) of the AC drive contain harmonics, which may interfere with the communication device connected to the AC drive. Therefore, install an antiinterference filter to minimize the interference. 3) For more details on peripheral devices, refer to related selection manual. 2.4.2 Description of Optional Parts The optional parts include braking unit of different functions and external operation panel, etc. If any optional part is required, specify it in your order.

If one row of AC drives need to be installed above another row, install an insulation guide plate . 3) Use incombustible hanging bracket. 3.2 Electrical Installation 3.2.1 Description of Main Circuit Terminals ■ Description of Main Circuit Terminals of Three-phase AC drive www.ssinverter.info SSI700 User Manual Mechanical and Electrical Installation Table 3-1 Description of main circuit terminals of three-phase AC drive Terminal Name Three-phase power supply input terminals B1, B2 Connecting terminals of braking resistor U, V, W AC drive output terminals Description Connect to the single-phase 220 VAC power supply. Connect to the braking resistor for the AC drive of 2.2 kW and below (220 V) and 7.5 kW and below (other voltage classes). Connect to a three-phase motor. Grounding terminal Must be grounded. R, S , T 3.2.2 Wiring of AC Drive Main Circuit ■ Precautions on the Wiring 1) Power input terminals R, S, T – The cable connection on the input side of the AC drive has no phase sequence requirement. – The specification and installation method of external power cables must comply with the local safety regulations and related IEC standards. – Use copper conductors of a proper size as power cables according to the recommended values in section 8.3. 2) Braking resistor connecting terminals B1 , B2 – The connecting terminals of the braking resistor are effective only for the AC configured with the built-in braking unit. – The cable length of the braking resistor shall be less than 5 m. Otherwise, it may damage the AC drive. 3) AC drive output terminals U, V, W – The specification and installation method of external power cables must comply with the local safety regulations and related IEC standards. – Use copper conductors of a proper size as power cables according to the recommended values in section 8.3. – The capacitor or surge absorber cannot be connected to the output side of the AC drive. Otherwise, it may cause frequent AC drive fault or even damage the AC drive. – If the motor cable is too long, electrical resonance will be generated due to the impact of distributed capacitance. This will damage the motor insulation or generate higher leakage current, causing the AC drive to trip in overcurrent protection. If the motor cable is greater than 100 m long, an AC output reactor must be installed close to the AC drive. 4) Terminal PE – This terminal must be reliably connected to the main earthing conductor. Otherwise, it may cause electric shock, mal-function or even damage to the AC drive. – Do not connect the earthing terminal to the neutral conductor of the power supply. – The impedance of the PE conductor must be able to withstand the large shortcircuit current that may arise when a fault occurs. – Select the size of the PE conductor according to the following table: Cross-sectional Area of a Phase Conductor (S) S ≤ 16 mm2 16 mm2 < S ≤ 35 mm2 35 mm2 < S Min. Cross-sectional Area of Protective Conductor (Sp) S 16 mm2 S/2 www.ssinverter.info SSI700 User Manual Mechanical and Electrical Installation – You must use a yellow/green cable as the PE conductor. 5) Requirements on upstream protection device – Install upstream protection device on the input power circuit. The protection device must provide the protections on overcurrent, short-circuit and electrical solation. – When selecting the protective device, you should consider the current capacity of the power cable, system overload capacity and short-circuit capacity of the upstream power distribution of the equipment. Generally, make selection according to the recommended values in section 8.4. 3.2.3 Description of Control Circuit Terminals [ ■ Terminal Arrangement of Control Circuit ■ Description of Control Circuit Terminals Table 3-3 Description of control circuit terminals Analog output Digital input Analog input Power supply Type Terminal Name Function Description Provide +10 V power supply to external unit.

Figure 4-1 Diagram of the operation panel 4.1.1 Description of Indicators • RUN ON indicates that the AC drive is in the running state, and OFF indicates that the AC drive is in the stop state. • LOCAL/REMOT It indicates whether the AC drive is operated by means of operation panel, terminals or communication. LOCAL/REMOT: OFF LOCAL/REMOT: ON LOCAL/REMOT: blinking • Operation panel control Terminal control Communication control FWD/REV ON indicates reverse rotation, and OFF indicates forward rotation. • TUNE/TC When the indicator is ON, it indicates torque control mode. When the indicator is blinking slowly, it indicates the auto-tuning state. When the indicator is blinking quickly, it indicates the fault state. • Unit Indicators www.ssinverter.info SSI700 User Manual Operation, Display and Application Example • Digital Display The 5-digit LED display is able to display the set frequency, output frequency, monitoring data and fault codes. 4.1.2 Description of Keys on the Operation Panel Table 4-1 Description of keys on the operation panel Key Name Function Programming Enter or exit Level I menu. Confirm Enter the menu interfaces level by level, and confirm the parameter setting. Increment Increase data or function code. Decrement Decrease data or function code. Shift Select the displayed parameters in turn in the stop or running state, and select the digit to be modified when modifying parameters. RUN Start the AC drive in the operation panel control mode. Stop/Reset Stop the AC drive when it is in the running state and perform the reset operation when it is in the fault state. The functions of this key are restricted in P7-02. Multifunction Perform function switchover (such as quick switchover of command source or direction) according to the setting of P7-01. AI0 Potentiometer on the key pad 4.2 Viewing and Modifying Function Codes The operation panel of the SSI700 adopts three-level menu. The three-level menu consists of function code group (Level I), function code (Level II), and function code setting value (level III), as shown in the following figure. Figure 4-2 Operation procedure on the operation panel www.ssinverter.info SSI700 User Manual • After you press Operation, Display and Application Example , the system saves the parameter setting first, and then goes back to Level II menu and shifts to the next function code. • After you press , the system does not save the parameter setting, but directly returns to Level II menu and remains at the current function code. Here is an example of changing the value of P3-02 to 15.00 Hz. Figure 4-3 Example of changing the parameter value In Level III menu, if the parameter has no blinking digit, it means that the parameter cannot be modified. This may be because: • Such a function code is only readable, such as, AC drive model, actually detected parameter and running record parameter. • Such a function code cannot be modified in the running state and can only be changed at stop. 4.3 Definition and Operation of the Multifunction Key (APP) You can define the function (command source switchover or rotation direction switchover) of the multifunction key in P7-01. For details, see the description of P7-01. 4.4 Viewing Status Parameters In the stop or running state, you can press on the operation panel to display status parameters.

Convert the binary data to hexadecimal data: P7-03: 007DH, P7-04: 2001H The values displayed on the operation panel are respectively H.1043 and H.2001 respectively for P7-03 and P7-04. 4.5 Starting or Stopping the AC Drive 4.5.1 Selecting the Start/Stop Command Source There are three start/stop command sources, namely, operation panel control, terminal control, and communication control. You can select the command source in P0-01. Function Code Parameter Name Setting Range Default Property 0 ☆ Group P0: Standard Function Parameters 0:Operation panel control (LED off) P0-01 Command source selection Run/Stop 1: Terminal control (LED on) 2: Communication control (LED blinking) It is used to determine the input channel of the AC drive control commands, such as run, stop, forward rotation, reverse rotation and jog operation. You can input the commands in the following three channels: • 0: Operation panel control ("LOCAL/REMOT" indicator off) Commands are given by pressing keys and on the operation panel. • 1: Terminal control ("LOCAL/REMOT" indicator on) Commands are given by means of multifunctional input terminals with functions such as FWD, REV, JOGF, and JOGR. This control mode is applicable to scenarios where the DIP switch or electromagnetic button is used to start or stop the application system or scenarios where the dry contact signal is used to start or stop the AC drive. The switch signal mode is set in P4-11. The input terminal of the start/stop signal is set in P4-00 to P4-09. For details, see the description of P4-11 and P4-00 to P4-09. Example 1: To use the DIP switch as the start/stop source, and allocate the forward rotation switch signal to DI2 and the reverse rotation switch signal to DI3, perform the setting as shown in the following figure. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example Figure 4-6 Setting of using the DIP switch for start/stop In the preceding figure, when SW1 is ON, the AC drive instructs forward rotation; when SW1 is OFF, the AC drive stops. When SW2 is ON, the AC drive instructs reverse running; when SW2 is OFF, the AC drive stops. If SW1 and SW2 are ON or OFF simultaneously, the AC drive stops. Example 2: To use the electromagnetic button as the start/stop source, and allocate the startup signal to DI2, stop signal to DI3 and reverse rotation signal to DI4, perform the setting as shown in the following figure. Figure 4-7 Setting of using the electromagnetic button for start/stop In the preceding figure, SB1 must stay ON during normal start and running. The AC drive stops immediately after SB1 becomes OFF. The signals from SB2 and SB3 become valid once they become ON. The running state of the AC drive is determined by the final actions on the three buttons. 2: Communication control The most common configuration is when the host computer is used to control running of the AC drive by means of communication, such as the RS485. The SSI700 interacts with the user programmable also by means of communication. Figure 4-8 Setting for start/stop using the communication control mode When 13-04 is set to a non-zero number, the function of automatic AC drive stop upon communication timeout is enabled. This prevents uncontrollable AC drive running due to faults of the communication cable or the host computer. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example The communication port of the AC drive supports the Modbus-RTU protocol, and the communication is implemented only when the host computer supports the Modbus- RTU master station protocol. 4.5.2 Start Mode The SSI700 supports three start modes, namely, direct start, rotational speed tracking restart, and pre-excited start (asynchronous motor), set in P6-00. • P6-00 = 0 (direct start) It is applicable to small-inertia load. The frequency curve in this mode is shown in the following figure. DC braking before the start is applicable to drive of load such as elevator and crane. Startup frequency is applicable to drive with burst start under start torque, such as cement mixer. Figure 4-9 Frequency curve of direct start P6-00 = 1 (Rotational speed tracking restart) It is applicable to large-inertia load. The frequency curve in this mode is shown in the following figure. If the load motor is still rotating due to the inertia when the AC drive starts, this mode is used to prevent start overcurrent. Figure 4-10 Frequency curve of rotational speed tracking restart • P6-00 = 2 (Pre-excited start) It is applicable only to inductive asynchronous motor. The AC drive performs preexcitation before start, improving quick response of the motor and meeting the requirements of short acceleration time. The frequency curve in this mode is shown in the following figure. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example Figure 4-11 Frequency curve of pre-excited start 4.5.3 Stop Mode The AC drive supports two stop modes, decelerate to stop and coast to stop, set in P6-10. Figure 4-12 Diagram of two stop modes (decelerate to stop and coast to stop) 4.5.4 Timing Stop The SSI700 supports timing stop. This function is enabled by P8-42 and the timing duration is determined by P8-43 and P8-44. Figure 4-13 Setting of the timing stop function You can set the timing duration by means of analog input (such as potentiometer signal). For details, see the description of P8-43. 4.5.5 JOG Running In certain applications, the AC drive needs to run in low speed temporarily to facilitate equipment test or other commissioning operations. In this case, you can set the AC drive to perform JOG running. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example Figure 4-14 JOG running ■ Parameter Setting and Operation of JOG Running in Operation Panel Control Figure 4-15 JOG running in operation panel control Set the parameters according to the preceding figure. In stop state of the AC drive, hold down , and the AC drive starts JOG running. After you release , the AC drive decelerates to stop. To perform reverse JOG, set P7-01 to 4 and P8-13 to 1. Hold down and the AC drive starts reverse JOG running. ■ Parameter Setting and Operation of JOG Running in DI Terminal Control For equipment that requires frequent JOG operations, such as textile machine, it is more convenient to control JOG running by using keys or buttons. To achieve convenient control, perform the setting according to the following figure. Figure 4-16 JOG running in DI terminal control www.ssinverter.info SSI700 User Manual Operation, Display and Application Example After performing the setting according to the preceding figure, press the FJOG button in stop state of the AC drive. Then, the AC drive starts forward JOG. After you press the FJOG button again, the AC drive decelerates to stop. 4.6 Setting the Running Frequency The AC drive provides two frequency sources, namely, main frequency source A and auxiliary frequency source B. You can select one frequency source and switch over between the two sources. You can also perform superposition on the two sources by setting the calculation formula to meet different control requirements of different scenarios. 4.6.1 Frequency Setting by the Main Frequency Source There are nine setting modes of main frequency sources, digital setting (UP/DOWN modification, non-retentive at power failure), digital setting (UP/DOWN modification, retentive at power failure), AI1, AI2, pulse setting, multi-reference, simple PLC, and communication setting. You can select one in P0-03. Figure 4-17 Frequency set by the main frequency source According to the preceding figure, the running frequency of the AC drive can be set by means of function codes, manual adjustment, analog input, multi-speed terminal, external feedback signal, internal PID regulator, or the host computer. Set the corresponding function codes of each frequency setting mode, as shown in the preceding figure. 4.6.2 Frequency Setting by the Auxiliary Frequency Source The frequency setting by the auxiliary frequency source is the same as the frequency setting by the main frequency source. You can set the auxiliary frequency source in P0-04. Figure 4-18 Frequency set by the auxiliary frequency source www.ssinverter.info SSI700 User Manual Operation, Display and Application Example The relationship between the target running frequency and the main frequency source and auxiliary frequency source is set in P0-07, as follows: 1) Main frequency source A: The main frequency source is directly used to set the target running frequency. 2) Auxiliary frequency source B: The auxiliary frequency source is directly used to set the target running frequency. 3) A and B operation: There are four operation methods, namely, A+B, A-B, maximum of A and B, and minimum of A and B. 4) Frequency switchover: A DI terminal is used to switch over between the preceding three frequency setting channels. The following figure shows how to set the relationship in P0-07, in which the bold line indicates the default setting. Figure 4-19 Relationship between the target running frequency and main and auxiliary frequency sources The operation between the main frequency source and the auxiliary frequency source can be used for closed-loop speed control. For example, using the main frequency source for setting the required frequency and the auxiliary frequency source for automatic adjustment, in conjunction with switchover performed by the external DI terminal signal, the required control can be implemented. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example 4.6.3 Binding Command Source to Frequency Source The three command sources can be separately bound to frequency sources, as shown in Figure 4-19. When the specified command source (P0-01) is bound to a frequency source (corresponding digit in the value of P0-27), the frequency is determined by the frequency setting channel set in P0-27. In this case, both main and auxiliary frequency sources are ineffective. 4.6.4 AI as the Frequency Source The AI terminal can be used as the frequency source. The SSI700 provides two AI terminals (AI1 and AI2) on the control board . The following figures show how to use the AI as the frequency source. Figure 4-20 Voltage input of AI1 connected to the potentiometer as the frequency source (2–10 V corresponding to 10–40 Hz) Figure 4-21 Current input of AI2 connected to 4DA module of the PLC as the frequency source (4–20 mA corresponding to 0–50 Hz) Notes 1. AI1 provides 0–10 V voltage input. AI2 provides 0–10 V voltage input or 4–20 mA current input, determined by jumper J8 on the control board. 2. When AI is used as the frequency source, 100% of the voltage or current input corresponding setting corresponds to the maximum frequency in P0-10. 3. SSI700 provides five corresponding relationship curves, which can be selected in P4-33. The input values and corresponding settings of each curve are set in P4-13 to P4-27 . 4.6.5 Pulse Setting as the Frequency Source In many scenarios, pulse input is used as the frequency source. The specifications of pulse signals are: voltage 9–30 V, frequency 0–100 kHz. Only DI5 can be used for pulse input. The relationship between pulse input from DI5 and the corresponding setting is set in P4-28 to P4-31. The relationship is a two-point line, and www.ssinverter.info SSI700 User Manual Operation, Display and Application Example 100% of pulse input corresponding setting corresponds to the maximum frequency of P0-10, as shown in Figure 4-22. Figure 4-22 Pulse setting as the frequency source 4.6.6 Frequency Closed-Loop Control The SS700 has a built-in PID regulator. Together with the frequency sources, the PID regulator can implement automatic adjustment of progress control, such as constant temperature, constant pressure, and tension control. Figure 4-23 Automatic adjustment by PID regulator When PID frequency closed-loop control is implemented, P0-03 (Main frequency source A selection) must be set to 8 (PID). The PID-related parameters are set in group 10, as shown in Figure 4-23. The SSI900 has two built-in equivalent PID calculating units. You can set the features, such as adjustment speed and accuracy, for the two units separately based on the actual conditions. Switchover between the two units can be implemented automatically or by means of an external DI terminal. 4.6.7 Multi-Speed Mode In scenarios where the running frequency of the AC drive need not be adjusted continuously and only several frequencies are required, the multi-speed control can be used. The SSI700 supports a maximum of 16 running frequencies, which are implemented by state combinations of four DI terminals. Set the function codes corresponding to DI terminals to a value among 12 to 15, and then the DI terminals are specified as the multi-frequency input terminals. The multiple frequencies are set based on the multi-frequency table in group 12. In addition, you need to set P0-03 (Main frequency source A selection) to 6 (Multireference). The following figure shows how to set the multi-speed function. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example Figure 4-24 Setting the multi-speed function In the preceding figure, DI7, DI4, DI8, and DI2 are used as the multi-frequency input terminals, each of which has a bit value. The state combinations of these terminals correspond to multiple frequencies, When (DI7, DI4, DI8, DI2) = (0, 0, 1, 0), the state combination value is 2, corresponding to the value set in 12-02. The target running frequency is automatically calculated by 12-02 x P0-10. The SSI700 supports a maximum of four DI terminals to be used as the multi-frequency input terminals. You can also use less than four DI terminals, and the empty bit is considered to be 0. 4.6.8 Setting the Motor Rotating Direction After the AC drive restores the default settings, press to drive the motor to rotate. In this case, the rotating direction is regarded as the forward rotation. If the rotating direction is reverse to the direction required by the equipment, power off the AC drive and exchange any two of the output UVW cables (wait until the main capacitor of the AC drive is completely discharged). In some applications where both forward rotation and reverse rotation are required, enable the reverse control (P8-13 = 0, default value) and meanwhile reverse the rotating direction by setting P0-09 to 1. Then press to make the motor rotate in the reverse direction, as shown in the following figure. Figure 4-25 Reversing the motor rotating direction If the command source is terminal control and reverse rotation is required, use the default value 0 of P8-13 to enable reverse control. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example According to the preceding figure, when the running frequency of the AC drive is set by means of communication (P0-03 = 9) and reverse control is enabled (P8-13 = 0), the AC drive instructs the reverse direction if the set frequency Fs is a negative value. If the give running command is reverse rotation or the set frequency is a negative value, but reverse control is disabled (P8-13 =1), the AC drive will run at 0 Hz and has no output. In some applications where reverse rotation is prohibited, do not change the rotating direction by modifying the function codes because the function codes will be restored once the AC drive restores the default settings. 4.6.9 Setting the Fixed Length Control Mode The SSI700 has the fixed length control function. The length pulses are sampled by the DI allocated with function 27 (Length count input). The "Actual length" (11-06) is obtained by dividing the number of pulses sampled by the value of 11-07 (Number of pulses per meter). If the actual length is larger than the "Set length" (11-05), the multifunctional DO terminal becomes ON. In the process of fixed length control, the length can be reset by means of the DI terminal allocated with function 28 (Length reset). The related setting is shown in the following figure. Figure 4-26 Function code setting for fixed length control Notes • In the fixed length control mode, the direction cannot be identified and only the length shall be calculated based on the number of pulses. • Only DI5 can be allocated with the function "Length count input". • An automatic stop system can be implemented if the length reached signal output by the DO is fed back to the AC drive input terminal with the stop function. Figure 4-27 Common application example of the fixed length control function www.ssinverter.info SSI700 User Manual Operation, Display and Application Example 4.6.10 Use of the Counting Function The count value needs to be collected by the DI terminal that is allocated with function 25. When the count value reaches 11-08 (Set count value), the DO terminal allocated with function 8 (Set count value reached) becomes ON. Then the counter stops counting. When the count value reaches 11-09 (Designated count value), the DO terminal allocated with function 9 (Designated count value reached) becomes ON. The counter continues to count until "Set count value" is reached. Figure 4-28 Parameter setting in the counting mode Notes • 11-09 (Designated count value) must not be greater than 11-08 (Set count value). • DI5 must be used when the pulse frequency is high. • The DO terminal that is allocated with function 9 (Designated count value reached) and the DO terminal that is allocated with function 8 (Set count value reached) must not be the same. • In the RUN/STOP state of the AC drive, the counter will not stop until "Set count value" is reached. • The count value is retentive at power failure. • An automatic stop system can be implemented if the signal output by the DO terminal with the function (Count value reached) is fed back to the DI terminal of the AC drive with stop function. 4.7 Setting and Auto-tuning of Motor Parameters 4.7.1 Motor Parameters to Be Set When the AC drive runs in the vector control mode (P0-00 = 0 or 1), accurate motor parameters are required to ensure desired driver performance and running efficiency. This is extremely different from the V/F control (P0-00 = 1). Motor parameters (motor 1 by default) that need to be set are listed in the following table. Table 4-2 Motor parameters to be set www.ssinverter.info SSI700 User Manual Operation, Display and Application Example Parameter P1-00 P1-01 to P1-05 P1-06 to P1-10 Description Remark Asynchronous motor, variablefrequency asynchronous motor, Motor type Rated motor power, Rated motor voltage, Rated motor current, Rated motor frequency, Rated motor rotational speed Motor internal equivalent stator resistance, inductive reactance and rotor inductance Model parameters, manual input Auto-tuning parameters 4.7.2 Motor Auto-tuning To obtain the motor parameters, the AC drive can perform dynamic auto-tuning or static auto-tuning. For the asynchronous motor that cannot be disconnected from the load, you can input the motor parameters of the same model that was successfully auto-tuned before. Auto-tuning No-load dynamic auto-tuning With-load dynamic auto-tuning Static auto-tuning Manual input Application Result It is applied to applications where the motor (synchronous motor or asynchronous motor) can be disconnected from the load. It is applied to applications where the motor asynchronous cannot be disconnected from the load. It is applied to applications where the motor (asynchronous motor only) cannot be disconnected from the load and dynamic auto-tuning is not allowed. It is applied to applications where the motor (asynchronous motor only) cannot be disconnected from the load. Input the motor parameters of the same model that was successfully autotuned before into function codes P1-00 to P1-10. Best OK Poor OK The following motor auto-tuning description takes motor 1 as an example. The process of motor auto-tuning is as follows: 1) If the motor can be disconnected from the load, disconnect the motor from the load mechanically after power-off so that the motor can run without load. 2) After power-on, set P0-01 (Command source selection) to 0 (Operation panel control). 3) Input the motor nameplate parameters (such as P1-00 to P1-05) correctly and input the following parameters based on the actually selected motor. P1-00: Motor type selection P1-01: Rated motor power P1-02: Rated motor voltage P1-03: Rated motor current P1-04: Rated motor frequency P1-05: Rated motor rotational speed For asynchronous motor, set P1-11 (Auto-tuning selection) to 2 (Asynchronous motor complete auto-tuning). Press Then press on the operation panel. The operation panel displays: on the operation panel. The AC drive will drive the motor to accelerate/ decelerate and run in the forward/reverse direction, and the RUN indicator is ON. The autotuning lasts approximately 2 minutes. When the preceding display information www.ssinverter.info SSI700 User Manual Operation, Display and Application Example disappears and the operation panel returns to the normal parameter display status, it indicates that the auto-tuning is complete. The AC drive will automatically calculate the following motor parameters: P1-06: Stator resistance (asynchronous motor) P1-07: Rotor resistance (asynchronous motor) P1-08: Leakage inductive reactance (asynchronous motor) P1-09: Mutual inductive reactance (asynchronous motor) P1-10: No-load current (asynchronous motor) If the motor cannot be disconnected from the load, set P1-11 (Auto-tuning selection) to 1 (Asynchronous motor static tuning) and then press motor auto-tuning starts. on the operation panel. The 4.7.3 Setting and Switchover of Multiple Groups of Motor Parameters You can select the current effective motor parameter group by means of function code P0-26 or DI terminals with functions 41 and 42. When the DI terminals with functions 41 and 42 become ON, they are privileged and the setting of P0-26 becomes invalid. 4.8 Use of DI Terminals The control board provides five DI terminals DI1 to DI5. The internal hardware of DI terminals are configured with 24 VDC power supply for detection. You can input a signal to a DI terminal of the AC drive only by shorting the DI terminal and COM. By default, P4-38 = 0000 and P4-39 = 0000. When a DI terminal is shorted to COM, it isactive (logic 1). When a DI terminal is not shorted to COM, it is inactive (logic 0). You can change the DI terminal active mode. That is, a DI terminal is inactive (logic 0) when being shorted with COM, and active (logic 1) when being not shorted to COM. In this case, it is necessary to change the corresponding bit in P4-38 and P4-39 (these two parameters respectively specifying the active mode setting of DI1 to DI5 and DI16 to DI10) to 1. The AC drive also provides P4-10 (DI filter time) for the DI signal to improve the antiinterference level. For DI1 to DI3, the AC drive provides the DI signal delay function, convenient for some applications requiring delay. Figure 4-29 DI delay setting The preceding 5 DI terminals can be defined in function codes P4-00 to P4-04. Each DI can be allocated with their respective function from the 50 functions. For details, see descriptions of P4-00 to P4-04. The hardware design allows only DI5 to receive high-speed pulse signal. If high-speed pulse count is required, use DI5. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example 4.9 Use of DO Terminals The control board provides three DO terminals, namely FM, DO1 and TA/TB/TC. FM and DO1 are transistor outputs and can drive 24 VDC low-voltage circuit; TA/TB/TC is relay output, and can drive 250 VAC control circuit. You can define the function of the DO terminals by setting P5-01 and P5-04 to indicate the running state and alarm information of the AC drive. There are a total of 40 functions. For details, see the descriptions of group P5. Terminal FM-CME TA-TB-TC DO1-CME Corresponding Function Code P5-06 when P5-00 = 0 P5-01 when P5-00 = 1 P5-02 P5-04 Output Feature Description Transistor, able to output high-speed pulses 10 Hz to 100 kHz; drive capacity: 24 VDC, 50 Ma Transistor; drive capacity: 24 VDC, 50 Ma Relay; drive capacity: 250 VAC, 3 A Transistor; drive capacity: 24 VDC, 50 mA When P5-00 = 0, the FM terminal is high-speed pulse output. The frequency of output pulses indicates the value of the internal running parameters. The greater the value is, the higher the output pulse frequency is. The 100% value corresponds to 100 kHz. The property of the indicated internal parameter is defined by P5-06. 4.10 Use of AI Terminals The AC drive supports a total of three AI terminals, among which AI1 and AI2 are provided on the control board. Terminal AI1-GND AI2-GND Input Signal Characteristic It receives the signal of 0–10 VDC. If J8 is connected to the position with "V" mark, it receives the signal of 0–10 VDC. If J8 is connected to the position with "I" mark, it receives the signal of 4–20 mA. As external voltage/current signal, AI is used for frequency source setting, torque setting, voltage setting at V/F separation, and PID setting or feedback. The corresponding relationship of the voltage or current and actual setting or feedback is defined by P4-13 to P4-27. Figure 4-30 Defining corresponding relationship of the voltage or current and actual setting or feedback The sampling of AI terminals can be queried in D0-09 to D0-11. The calculation value is for internal subsequent calculation and cannot be directly read by the user. 4.11 Use of AO Terminals The AC drive supports a total of two AO terminals, among which AO1 is provided by the control board. www.ssinverter.info SSI700 User Manual Terminal AI1-GND AI2-GND Operation, Display and Application Example Input Signal Characteristic It receives the signal of 0–10 VDC. If J8 is connected to the position with "V" mark, it receives the signal of 0–10 VDC. If J8 is connected to the position with "I" mark, it receives the signal of 4–20 mA. AO1 can be used to indicate the internal running parameters in the analog mode. The property of indicated parameters can be defined by P5-07 and P5-08. The designated running parameters can be rectified before output. The rectification feature is Y = kX + b, among which "X" indicates the running parameters to be output, and "k" and "b" of AO1 can be set by P5-10 and P5-11. Figure 4-31 Setting of "k" and "b" of AO1 4.12 Use of Serial Communication When communication mode RS485 on the SSI700 series AC drive, and set P0-28 correctly according to the used communication protocol type. For the configuration of hardware communication parameters for the communication port, see group 13. Set the communication rate and data format to consistent with those of the host computer, which is the precondition of normal communication. The SSI700 serial port itself supports the Modbus RTU slave communication protocol. You can query or modify the AC drive's function codes, query various running state parameters, and send running command and running frequency to the AC drive from the host computer through the serial port. Figure 4-32 Communication control mode of the AC drive The SSI700 arranges the function codes, running state parameters and running commands in the "register parameter address" mode. The host computer can define the protocol of communication data interaction. 4.13 Password Setting The AC drive provides the user password protection function. When 16-00 is set to a nonzero value, the value is the user password. The password takes effect after you after exit the function code editing state. When you press again, "------" will be displayed, and you must enter the correct user password to enter the menu. To cancel the password protection function, enter with password and set 16-00 to 0. www.ssinverter.info SSI700 User Manual Operation, Display and Application Example 4.14 Parameter Saving and Default Setting Restoring After a function code is modified on the operation panel, the modification will be saved in the register of the AC drive and remain effective at next power-on. The AC drive supports backup and restoration of parameter setting, which is convenient for commissioning. The AC drive also provides the retentive function on alarm information and accumulative running time. You can restore the backup values or default settings of the function codes of the AC drive or clear the running data through 16-01. For details, see the description of 16-01. Figure 4-35 Parameter saving and default parameter restoring www.ssinverter.info Function Code Table SSI700 User Manual Function Code Chapter 5 Function Code Table If 16-00 is set to a non-zero number, parameter protection is enabled. You must enter the correct user password to enter the menu. To cancel the password protection function, enter with password and set 16-00 to 0. Group P are standard function parameters. The symbols in the function code table are described as follows: "☆": The parameter can be modified when the AC drive is in either stop or running state. "★": The parameter cannot be modified when the AC drive is in the running state. "●": The parameter is the actually measured value and cannot be modified. "*": The parameter is factory parameter and can be set only by the manufacturer. 5 Standard Function Parameters Function Code P0-00 Parameter Name Setting Range Group P0: Standard Function Parameters 0:Sensorless flux vector control (SFVC) Motor control mode 1: Voltage/Frequency (V/F) control Default Property 0 ★ 0 ☆ 1 * 10 ★ 1 ★ 0 ☆ 100% ☆ 0:Operation panel control (LED off) P0-01 Command source selection Run/Stop P0-02 G/P(Motor) type display P0-03 Main frequency source A selection P0-04 P0-05 P0-06 Auxiliary frequency source B selection Range of auxiliary frequency B for A and B operation Range of auxiliary frequency B for A and B operation 1: Terminal control (LED on) 2: Communication control (LED blinking) 1:G type(constant torque load) 0: Digital setting Preset P0-08, UP/DOWN Can be modified.

You can set the main frequency in the following 10 channels: • 0: Digital setting (non-retentive at power failure) The initial value of the set frequency is the value of P0-08 (Preset frequency). You can change the set frequency by pressing and on the operation panel (or using the UP/DOWN function of input terminals). When the AC drive is powered on again after power failure, the set frequency reverts to the value of P0-08. • 1: Digital setting (retentive at power failure) The initial value of the set frequency is the value of P0-08 (Preset frequency). You can change the set frequency by pressing keys and on the operation panel (or using the UP/DOWN function of input terminals). When the AC drive is powered on again after power failure, the set frequency is the value memorized at the moment of the last power failure. Notes that P0-23 (Retentive of digital setting frequency upon power failure) determines whether the set frequency is memorized or cleared when the AC drive stops. It is related to stop rather than power failure. • 2: AI1 (0–10 V voltage input) • 3: AI2 (0–10 V voltage or 4–20 mA current input, determined by jumper J8) The frequency is set by analog input. The SSI700 control board provides two analog input (AI) terminals (AI1, AI2). The SSI700 provides five curves indicating the mapping relationship between the input voltage of AI1, AI2 and the target frequency, three of which are linear (pointpoint) correspondence and two of which are four-point correspondence curves. You can set the curves by using function codes P4-13 to P4-27 and function codes in select curves for AI1, AI2. When AI is used as the frequency setting source, the corresponding value 100% of the voltage/current input corresponds to the value of P0-10 (Maximum frequency). • 5: Pulse setting (DI5) The frequency is set by DI5 (high-speed pulse). The signal specification of pulse setting is 9–30 V (voltage range) and 0–100 kHz (frequency range). The corresponding value 100% of pulse setting corresponds to the value of P0-10 (Maximum frequency). www.ssinverter.info SSI700 User Manual • Description of Function Codes 6: Multi-reference In multi-reference mode, combinations of different DI terminal states correspond to different set frequencies. The SSI700 supports a maximum of 16 speeds implemented by 16 state combinations of four DI terminals (allocated with functions 12 to 15) in Group 12. The multiple references indicate percentages of the value of P0-10 (Maximum frequency). If a DI terminal is used for the multi-reference function, you need to perform related setting in group P4. • 7: Simple PLC When the simple programmable logic controller (PLC) mode is used as the frequency source, the running frequency of the AC drive can be switched over among the 16 frequency references. You can set the holding time and acceleration/deceleration time of the 16 frequency references. For details, refer to the descriptions of Group 12. • 8: PID The output of PID control is used as the running frequency. PID control is generally used in on-site control, such as constant pressure control and constant tension control. When applying PID as the frequency source, you need to set parameters of PID function in group 10. • 9: Communication setting The frequency is set by means of communication. If the AC drive is a slave in point-point communication and receives data as the frequency source, data transmitted by the master is used as the set frequency. The data format is -100.00% to 100.00%. 100% corresponds to the value of P0-10 (Maximum frequency). In other conditions, data is given by the host computer through the communication address 0x1000. The data format is -100.00% to 100.00%. 100.00% corresponds to the value of P0-10 (Maximum frequency). The SSI700 supports four host computer communication protocols: Modbus. They cannot be used simultaneously. If the communication mode is used. • Function Code P0-04 10: Potentiometer key pad When AI is used as the frequency setting source, the corresponding value 100% of the voltage input corresponds to the value of P0-10 (Maximum frequency).

When the auxiliary frequency source is used for operation (frequency source is "A and B operation"), pay attention to the following aspects: www.ssinverter.info SSI700 User Manual Description of Function Codes 1) If the auxiliary frequency source A is digital setting, the preset frequency (P0-08) does not take effect. You can directly adjust the set main frequency by pressing keys and on the operation panel (or using the UP/DOWN function of input terminals). 2) If the auxiliary frequency source is analog input (AI1, AI2) or pulse setting, 100% of the input corresponds to the range of the auxiliary frequency B (set in P0-05 and P0-06). 3) If the auxiliary frequency source is pulse setting, it is similar to analog input. Notes The main frequency source A and auxiliary frequency source B must not use the same channel. That is, P0-03 and P0-04 cannot be set to the same value.

Modifying this parameter is equivalent to exchanging any two ofthe motor's U, V, W wires. Notes The motor will resume running in the original direction after parameter initialization. Do not use this function in applications where changing the rotating direction of the motor is prohibited after system commissioning is complete. Function Code P0-10 Parameter Name Setting Range Group P0: Standard Function Parameters Vector : 50.00–320.00 Hz Maximum frequency V/F : 50.00–3200.00 Hz Default Property 50.00 Hz ★ When the frequency source is AI, pulse setting (DI5), or multi-reference, 100% of the input corresponds to the value of this parameter. The output frequency of the SSI700 can reach up to 3200 Hz. To take both frequency reference resolution and frequency input range into consideration, you can set the number of decimal places for frequency reference in P0-22. www.ssinverter.info SSI700 User Manual Description of Function Codes • If P0-22 is set to 1, the frequency reference resolution is 0.1 Hz. In this case, thesetting range of P0-10 is 50.0 to 3200.0 Hz. • If 0-22 is set to 2, the frequency reference resolution is 0.01 Hz. In this case, the setting range of P0-10 is 50.00 to 320.00 Hz. Notes After the value of P0-22 is modified, the frequency resolution of all frequency related function codes change accordingly.

Function Code P0-15 Parameter Name Setting Range Group P0: Standard Function Parameters Carrier frequency 0.5–16.0 kHz Default Property Model dependent ☆ It is used to adjust the carrier frequency of the AC drive, helping to reduce the motor noise, avoiding the resonance of the mechanical system, and reducing the leakage current to the earth and interference generated by the AC drive. www.ssinverter.info SSI700 User Manual Description of Function Codes If the carrier frequency is low, output current has high harmonics, and the power loss and temperature rise of the motor increase. If the carrier frequency is high, power loss and temperature rise of the motor declines. However, the AC drive has an increase in power loss, temperature rise and interference. Adjusting the carrier frequency will exert influences on the aspects listed in the following table. Table 6-1 Influences of carrier frequency adjustment Carrier frequency Motor noise Output current waveform Motor temperature rise AC drive temperature rise Leakage current External radiation interference Low Large Bad High Low Small Small High Small Good Low High Large Large The factory setting of carrier frequency varies with the AC drive power. If you need to modify the carrier frequency, note that if the set carrier frequency is higher than factory setting, it will lead to an increase in temperature rise of the AC drive's heatsink. In this case, you need to de-rate the AC drive. Otherwise, the AC drive may overheat and alarm. Function Code P0-16 Parameter Name Setting Range Group P0: Standard Function Parameters Carrier frequency adjustment 0: No with temperature 1: Yes Default Property 1 ☆ It is used to set whether the carrier frequency is adjusted based on the temperature. The AC drive automatically reduces the carrier frequency when detecting that the heatsink temperature is high. The AC drive resumes the carrier frequency to the set value when the heatsink temperature becomes normal. This function reduces the overheat alarms.

Before performing static auto-tuning, properly set the motor type and motor nameplate parameters of P1-00 to P1-05 first. The AC drive will obtain parameters of P1-06 to P1-08 by static auto-tuning. Set this parameter to 1, and press • Then, the AC drive starts static auto-tuning. 2: Asynchronous motor complete auto-tuning To perform this type of auto-tuning, ensure that the motor is disconnected from the load. During the process of complete auto-tuning, the AC drive performs static auto-tuning first and then accelerates to 80% of the rated motor frequency within the acceleration time set in P0-17. The AC drive keeps running for a certain period and then decelerates to stop within deceleration time set in P0-18. Before performing complete auto-tuning, properly set the motor type, motor nameplate parameters of P1-00 to P1-05. Set this parameter to 2, and press Then, the AC drive starts complete autotuning.

Figure 6-3 Relationship between running frequencies and PI parameters The speed dynamic response characteristics in vector control can be adjusted by setting the proportional gain and integral time of the speed regulator. To achieve a faster system response, increase the proportional gain and reduce the integral time. Be aware that this may lead to system oscillation. The recommended adjustment method is as follows: If the factory setting cannot meet the requirements, make proper adjustment. Increase the proportional gain first to ensure that the system does not oscillate, and then reduce the integral time to ensure that the system has quick response and small overshoot. Notes Improper PI parameter setting may cause too large speed overshoot, and overvoltage fault may even occur when the overshoot drops. Function Code P2-06 Parameter Name Setting Range Group P2: Vector Control Parameters Time constant of speed 0.000–0.100s loop filter Default Property 0.000s ☆ For SFVC, it is used to adjust speed stability accuracy of the motor. When the motor with load runs at a very low speed, increase the value of this parameter; when the motor with load runs at a very large speed, decrease the value of this parameter. www.ssinverter.info SSI700 User Manual Function Code P2-07 Parameter Name Description of Function Codes Setting Range Group P2: Vector Control Parameters Vector control slip gain 50%–200% Default Property 100% ☆ In the vector control mode, the output of the speed loop regulator is torque current reference. This parameter is used to filter the torque references. It need not be adjusted generally and can be increased in the case of large speed fluctuation. In the case of motor oscillation, decrease the value of this parameter properly. If the value of this parameter is small, the output torque of the AC drive may fluctuate greatly, but the response is quick. Function Code P2-08 Parameter Name Setting Range Group P2: Vector Control Parameters Vector control 0–200 overexcitation gain Default Property 64 ☆ During deceleration of the AC drive, over-excitation control can restrain rise of the bus voltage to avoid the overvoltage fault. The larger the over-excitation gain is, the better the restraining effect is. Increase the over-excitation gain if the AC drive is liable to overvoltage error during deceleration. Too large over-excitation gain, however, may lead to an increase in output current. Therefore, set this parameter to a proper value in actual applications. Set the over-excitation gain to 0 in applications of small inertia (the bus voltage will not rise during deceleration) or where there is a braking resistor. Function Code P2-09 P2-10 Parameter Name Setting Range Group P2: Vector Control Parameters Digital setting of torque upper limit in speed 0.0%–200.0% control mode 0: P2-10 1: AI1 Torque upper limit 2: AI2 source in speed control 3: Reserved mode 4: Pulse setting (DI5) 5: Communication setting Default Property 150% ☆ 0 ☆ In the speed control mode, the maximum output torque of the AC drive is restricted by P2-10. If the torque upper limit is analog, pulse or communication setting, 100% of the setting corresponds to the value of P2-09, and 100% of the value of P2-09 corresponds to the AC drive rated torque. For details on the AI1, AI2 setting,see the description of the AI curves in group P4. For details on the pulse setting, see the description of P4-28 to P4-32. When the AC drive is in communication with the master, if P2-10 is set to 5 “communication setting”, P2-09 “Digital setting of torque upper limit in speed control mode” can be set via communication from the master. In other conditions, the host computer writes data -100.00% to 100.00% by the communication address 0x1000, where 100.0% corresponds to the value of P2-09. The communication protocol can be Modbus.

These parameters are automatically obtained through "Asynchronous motor complete auto-tuning".and need not be modified. The dimension of the current loop integral regulator is integral gain rather than integral time. Notes that too large current loop PI gain may lead to oscillation of the entire control loop. Therefore, when current oscillation or torque fluctuation is great, manually decrease the proportional gain or integral gain here. Function Code P2-17 Parameter Name Setting Range Group P2: Vector Control Parameters Unit's digit: integral separation 0: Disabled 1: Enabled Speed loop integral property Default Property 0 ☆ Group P3: V/F Control Parameters Group P3 is valid only for V/F control. The V/F control mode is applicable to low load applications (fan or pump) or applications where one AC drive operates multiple motors or there is a large difference between the AC drive power and the motor power. Function Code P3-00 P3-01 Parameter Name Setting Range Group P3: V/F Control Parameters Cut-off frequency of 0.00 Hz to maximum output torque boost frequency 0.0% (fixed torque boost) 0.1%– Torque boost 30.0% Default Property 50.0HZ ★ Model dependent ☆ To compensate the low frequency torque characteristics of V/F control, you can boost the output voltage of the AC drive at low frequency by modifying P3-01. If the torque boost is set to too large, the motor may overheat, and the AC drive may suffer overcurrent. If the load is large and the motor startup torque is insufficient, increase the value of P3-01. If the load is small, decrease the value of P3-01. If it is set to 0.0, the AC drive performs automatic torque boost. In this case, the AC drive automatically calculates the torque boost value based on motor parameters including the stator resistance. P3-00 specifies the frequency under which torque boost is valid. Torque boost becomes invalid when this frequency is exceeded, as shown in the following figure.

The multi-point V/F curve is set based on the motor's load characteristic. The relationship between voltages and frequencies is: V1 < V2 < V3, F1 < F2 < F3 At low frequency, higher voltage may cause overheat or even burnt out of the motor and overcurrent stall or overcurrent protection of the AC drive.

It can compensate the rotational speed slip of the asynchronous motor when the load of the motor increases, stabilizing the motor speed in case of load change. If this parameter is set to 100%, it indicates that the compensation when the motor bears rated load is the rated motor slip. The rated motor slip is automatically obtained by the AC drive through calculation based on the rated motor frequency and rated motor rotational speed in group P1. Generally, if the motor rotational speed is different from the target speed, slightly adjust this parameter. Function Code P3-10 Parameter Name Setting Range Group P3: V/F Control Parameters V/F over-excitation gain 0–200 Default Property 64 ☆ During deceleration of the AC drive, over-excitation can restrain rise of the bus voltage, preventing the overvoltage fault. The larger the over-excitation is, the better the restraining result is. Increase the over-excitation gain if the AC drive is liable to overvoltage error during deceleration. However, too large over-excitation gain may lead to an increase in the output current. Set P3-09 to a proper value in actual applications. Set the over-excitation gain to 0 in the applications where the inertia is small and the bus voltage will not rise during motor deceleration or where there is a braking resistor. Function Code Parameter Name Setting Range Default Property Model dependent ☆ Group P3: V/F Control Parameters P3-11 V/F oscillation suppression gain 0–100 Set this parameter to a value as small as possible in the prerequisite of efficient oscillation suppression to avoid influence on V/F control. Set this parameter to 0 if the motor has no oscillation. Increase the value properly only when the motor has obvious oscillation. The larger the value is, the better the oscillation suppression result will be. When the oscillation suppression function is enabled, the rated motor current and noload current must be correct. Otherwise, the V/F oscillation suppression effect will not be satisfactory. Group P4: Input Terminals The SSI700 provides five DI terminals (DI5 can be used for high-speed pulse input) and 3analog input (AI) terminals.

The terminal is used to control forward or reverse RUN of the AC drive. The terminal determines three-line control of the AC drive. For details, see the description of P4-11. FJOG indicates forward JOG running, while RJOG indicates reverse JOG running. The JOG frequency, acceleration time and deceleration time are described respectively in P8-00, P8-01 and P8-02. If the frequency is determined by external terminals, the terminals with the two functions are used as increment and decrement commands for frequency modification. When the frequency source is digital setting, they are used to adjust the frequency. The AC drive blocks its output, the motor coasts to rest and is not controlled by the AC drive. It is the same as coast to stop described in P6-10. The terminal is used for fault reset function, the same as the function of RESET key on the operation panel. Remote fault reset is implemented by this function. The AC drive decelerates to stop, but the running parameters are all memorized, such as PLC, swing frequency and PID parameters. After this function is disabled, the AC drive resumes its status before stop. If this terminal becomes ON, the AC drive reports Err and performs the fault protection action. For more details, see the description of P9-47. The setting of 16 speeds or 16 other references can be implemented through combinations of 16 states of these four terminals. Totally four groups of acceleration/deceleration time can be selected through combinations of two states of these two terminals. The terminal is used to perform switchover between two frequency sources according to the setting inP0-07 If the frequency source is digital setting, the terminal is used to clear the modification by using the UP/ DOWN function or the increment/decrement key on the operation panel, returning the set frequency to the value of P0-08. If the command source is set to terminal control (P0-01= 1), this terminal is used to perform switchover between terminal control and operation panel control. If the command source is set to communication control (P0-01= 2), this terminal is used to perform switchover between communication control and operation panel control. It enables the AC drive to maintain the current frequency output without being affected by external signals (except the STOP command). PID is invalid temporarily. The AC drive maintains the current frequency output without supporting PID adjustment of frequency source. The terminal is used to restore the original status of PLC control for the AC drive when PLC control is started again after a pause. www.ssinverter.info SSI700 User Manual Value Function 24 Swing pause 25 26 27 28 Counter input Counter reset Length count input Length reset 29 30 31 32 33 34 35 Torque control prohibited Pulse input (enabled only for DI5) Reserved Immediate DC braking Normally closed (NC) input of external fault Frequency modification forbidden Reverse PID action direction 36 External STOP terminal 1 37 Command source switchover terminal 2 38 PID integral pause 41,42 Switchover between main frequency source A and preset frequency Switchover between auxiliary frequency source B and preset frequency Reserved 43 PID parameter switchover 39 40 44,45 Reserved 46 Speed control/Torque control switchover 47 Emergency stop 48 External STOP terminal 2 49 Deceleration DC braking 50 Clear the current running time Description of Function Codes Description The AC drive outputs the central frequency, and the swing frequency function pauses. This terminal is used to count pulses. This terminal is used to clear the counter status. This terminal is used to count the length. This terminal is used to clear the length. The AC drive is prohibited from torque control and enters the speed control mode. DI5 is used for pulse input. Reserved. After this terminal becomes ON, the AC drive directly switches over to the DC braking state. After this terminal becomes ON, the AC drive reports Err and stops. After this terminal becomes ON, the AC drive does not respond to any frequency modification. After this terminal becomes ON, the PID action direction is reversed to the direction set in 10-03. In operation panel mode, this terminal can be used to stop the AC drive, equivalent to the function of the STOP key on the operation panel. It is used to perform switchover between terminal control and communication control. If the command source is terminal control, the system will switch over to communication control after this terminal becomes ON. After this terminal becomes ON, the integral adjustment function pauses. However, the proportional and differentiation adjustment functions are still valid. After this terminal becomes ON, the frequency source A is replaced by the preset frequency set in P0-08. After this terminal is enabled, the frequency source B is replaced by the preset frequency set in P0-08. Reserved. If the PID parameters switchover performed by means of DI terminal (10-18 =1), the PID parameters are 10-05 to 10-07 when the terminal becomes OFF; the PID parameters are 10-15 to 10-17 when this terminal becomes ON. Reserved. This terminal enables the AC drive to switch over between speed control and torque control. When this terminal becomes OFF, the AC drive runs in the mode set in 17-00. When this terminal becomes ON, the AC drive switches over to the other control mode. When this terminal becomes ON, the AC drive stops within the shortest time. During the stop process, the current remains at the set current upper limit. In any control mode (operation panel, terminal or communication), it can be used to make the AC drive decelerate to stop. In this case, the deceleration time is deceleration time 4. When this terminal becomes ON, the AC drive decelerates to the initial frequency of stop DC braking and then switches over to DC braking state. When this terminal becomes ON, the AC drive's current running time is cleared. This function must be supported by P8-42 and P8-53. www.ssinverter.info SSI700 User Manual Description of Function Codes The four multi-reference terminals have 16 state combinations, corresponding to 16 reference values, as listed in the following table.

Such smooth start has no impact on the rotating motor. It is applicable to the restart upon instantaneous power failure of large-inertia load. To ensure the performance of rotational speed tracking restart, set the motor parameters in group P1 correctly. • 2: Pre-excited start (asynchronous motor) It is valid only for asynchronous motor and used for building the magnetic field before the motor runs. For pre-excited current and pre-excited time, see parameters of P6-05 and P6-06. –– If the pre-excited time is 0, the AC drive cancels pre-excitation and starts to run at startup frequency. –– If the pre-excited time is not 0, the AC drive pre-excites first before startup, improving the dynamic response of the motor.

Pre-excitation is used to make the AC drive build magnetic field for the asynchronous motor before startup to improve the responsiveness. Startup DC braking is valid only for direct start (P6-00 = 0). In this case, the AC drive performs DC braking at the set startup DC braking current. After the startup DC braking time, the AC drive starts to run. If the startup DC braking time is 0, the AC drive starts directly without DC braking. The larger the startup DC braking current is, the larger the braking force is. www.ssinverter.info SSI700 User Manual Description of Function Codes If the startup mode is pre-excited start (P6-00 = 3), the AC drive builds magnetic field based on the set pre-excited current. After the pre-excited time, the AC drive starts to run. If the pre-excited time is 0, the AC drive starts directly without pre-excitation. The startup DC braking current or pre-excited current is a percentage relative to the base value. • If the rated motor current is less than or equal to 80% of the rated AC drive current, the base value is the rated motor current. • If the rated motor current is greater than 80% of the rated AC drive current, the base value is 80% of the rated AC drive current.

They must satisfy the requirement: P6-08 + P6-09 ≤ 100.0%. In Figure 6-12, t1 is the time defined in P6-08, within which the slope of the output frequency change increases gradually. t2 is the time defined in P6-09, within which the slope of the output frequency change gradually decreases to 0.

The motor is exposed to potential damage due to overheating. A thermal relay is suggested to be installed between the AC drive and the motor. • P9-00 = 1 The AC drive judges whether the motor is overloaded according to the inverse time-lag curve of the motor overload protection. The inverse time-lag curve of the motor overload protection is: 220% x P9-01 x rated motor current (if the load remains at this value for one minute, the AC drive reports motor overload fault), or 150% x P9-01 x rated motor current (if the load remains at this value for 60 minutes, the AC drive reports motor overload fault) Set P9-01 properly based on the actual overload capacity.

After the bus voltage declines, the AC drive continues to decelerate. P9-03 (Overvoltage stall gain) is used to adjust the overvoltage suppression capacity of the AC drive. The larger the value is, the greater the overvoltage suppression capacity will be. In the prerequisite of no overvoltage occurrence, set P9-03 to a small value. For small-inertia load, the value should be small. Otherwise, the system dynamic response will be slow. For large-inertia load, the value should be large. Otherwise, the suppression result will be poor and an overvoltage fault may occur. If the overvoltage stall www.ssinverter.info SSI700 User Manual Description of Function Codes gain is set to 0, the overvoltage stall function is disabled.

After the output current declines, the AC drive continues to accelerate/decelerate. P9-05 (Overcurrent stall gain) is used to adjust the overcurrent suppression capacity of the AC drive. The larger the value is, the greater the overcurrent suppression capacity will be. In the prerequisite of no overcurrent occurrence, set P9-05 to a small value. For small-inertia load, the value should be small. Otherwise, the system dynamic response will be slow. For large-inertia load, the value should be large. Otherwise, the suppression result will be poor and overcurrent fault may occur. If the overcurrent stall gain is set to 0, the overcurrent stall function is disabled.

AI1 is 0–10 V voltage input, AI2 is 0–10 V voltage input or 4–20 mA current input decided by jumper J8 on the control board is -10 V to +10 V voltage input. The SSI700 provides five curves indicating the mapping relationship between the input voltage of AI1, AI2 and the target frequency, three of which are linear (pointpoint) correspondence and two of which are four-point correspondence curves. You can set the curves by using function codes P4-13 to P4-27 and select curves for AI1, AI2 . When AI is used as frequency setting source, the corresponding value 100% of voltage/ current input corresponds to the value of 17-03. • 4: Pulse setting (DI5) The target torque is set by DI5 (high-speed pulse). The pulse setting signal specification is 9–30 V (voltage range) and 0–100 kHz (frequency range). The pulse can only be input via DI5. The relationship (which is a two-point line) between DI5 input pulse frequency and the corresponding value is set in P4-28 to P4-31. The corresponding value 100.0% of pulse input corresponds to the value of 17-03. • 5: Communication setting The target torque is set by means of communication. If the AC drive is a slave in point-point communication and receives data as torque source, data transmitted by the master is used as the setting value. For details, see the description of group 13. In other conditions, data is given by host computer through the communication address 0x1000. The data format is -100.00% to 100.00%. 100% corresponds to the value of 17-03. www.ssinverter.info SSI700 User Manual Description of Function Codes The SSI700 provides four communication and you can select one based on actual requirements. Function Code 17-05 17-06 Parameter Name Setting Range Group 17: Torque Control and Restricting Parameters Forward maximum 0.00 Hz to maximum frequency frequency in torque (P0-10) control Reverse maximum 0.00 Hz to maximum frequency frequency in torque (P0-10) control Default Property 50.00 Hz ☆ 50.00 Hz ☆ two parameters are used to set the maximum frequency in forward or reverse rotation in torque control mode. In torque control, if the load torque is smaller than the motor output torque, the motor's rotational speed will rise continuously. To avoid runaway of the mechanical system, the motor maximum rotating speed must be limited in torque control. You can implement continuous change of the maximum frequency in torque control dynamically by controlling the frequency upper limit. Function Code 17-07 17-08 Parameter Name Setting Range Group 17: Torque Control and Restricting Parameters Acceleration time in 0.00–65000s torque control Deceleration time in 0.00–65000s torque control Default Property 0.00s ☆ 0.00s ☆ In torque control, the difference between the motor output torque and the load torque determines the speed change rate of the motor and load. The motor rotational speed may change quickly and this will result in noise or too large mechanical stress. The setting of acceleration/deceleration time in torque control makes the motor rotational speed change softly. However, in applications requiring rapid torque response, set the acceleration/ deceleration time in torque control to 0.00s. For example, two AC drives are connected to drive the same load. To balance the load allocation, set one AC drive as master in speed control and the other as slave in torque control. The slave receives the master's output torque as the torque command and must follow the master rapidly. In this case, the acceleration/deceleration time of the slave in torque control is set to 0.0s. www.ssinverter.info EMC SSI700 User Manual EMC Chapter 7 EMC 7.1 Definition of Terms 1) EMC Electromagnetic compatibility (EMC) describes the ability of electronic and electrical devices or systems to work properly in the electromagnetic environment and not to generate electromagnetic interference that influences other local devices or systems. In other words, EMC includes two aspects: The electromagnetic interference generated by a device or system must be restricted within a certain limit; the device or system must have sufficient immunity to the electromagnetic interference in the environment. 2) First environment Environment that includes domestic premises, it also includes establishments directly connected without intermediate transformers to a low-voltage power supply network which supplies buildings used for domestic purposes 3) Second environment Environment that includes all establishments other than those directly connected to a lowvoltage power supply network which supplies buildings used for domestic purposes 4) Category C1 AC drive Power Drive System (PDS) of rated voltage less than 1000 V, intended for use in the first environment 5) Category C2 AC drive PDS of rated voltage less than 1000 V, which is neither a plug in device nor a movable device and, when used in the first environment, is intended to be installed and commissioned only by a professional 6) Category C3 AC drive PDS of rated voltage less than 1000 V, intended for use in the second environment and not intended for use in the first environment 7) Category C4 AC drive PDS of rated voltage equal to or above 1000 V, or rated current equal to or above 400 A, or intended for use in complex systems in the second environment 7.2 Introduction to EMC Standard 7.2.1 EMC Standard The SSI700 series AC drive satisfies the requirements of standard EN 61800-3: 2004 Category C2. The AC drives are applied to both the first environment and the second environment. 7.2.2 Installation Environment The system manufacturer using the AC drive is responsible for compliance of the system with the European EMC directive. Based on the application of the system, the integrator must ensure that the system complies with standard EN 61800-3: 2004 Category C2, C3 or C4. Warning If applied in the first environment, the AC drive may generate radio interference. Besides the CE compliance described in this chapter, users must take measures to avoid such interference, if necessary. www.ssinverter.info SSI700 User Manual EMC 7.3 Selection of Peripheral EMC Devices 7.3.1 Installation of EMC Input Filter on Power Input Side An EMC filter installed between the AC drive and the power supply can not only restrict the interference of electromagnetic noise in the surrounding environment on the AC drive, but also prevents the interference from the AC drive on the surrounding equipment. The SSI700 series AC drive satisfies the requirements of category C2 only with an EMC filter installed on the power input side. The installation precautions are as follows: • Strictly comply with the ratings when using the EMC filter. The EMC filter is category I electric apparatus, and therefore, the metal housing ground of the filter should be in good contact with the metal ground of the installation cabinet on a large area, and requires good conductive continuity. Otherwise, it will result in electric shock or poor EMC effect. • The ground of the EMC filter and the PE conductor of the AC drive must be tied to the same common ground. Otherwise, the EMC effect will be affected seriously. • The EMC filter should be installed as closely as possible to the power input side of the AC drive. The following table lists the recommended manufacturers and models of EMC filters for the SSI700 series AC drive. Select a proper one based on actual requirements. 7.3.2 Installation of AC Input Reactor on Power Input Side An AC input reactor is installed to eliminate the harmonics of the input current. As an optional device, the reactor can be installed externally to meet strict requirements of an application environment for harmonics. The following table lists the recommended manufacturers and models of input reactors. 7.3.3 Installation of AC Output Reactor on Power Output Side Whether to install an AC output reactor on the power output side is dependent on the actual situation. The cable connecting the AC drive and the motor should not be too long; capacitance enlarges when an over-long cable is used and thus high-harmonics current may be easily generated. If the length of the output cable is equal to or greater than the value in the following table, install an AC output reactor on the power output side of the AC drive. Table 7-1 Cable length threshold when an AC output reactor is installed AC Drive Power (kW) ≥4KW Rated Voltage (V) 200~500V Cable Length Threshold (m) 50M Table 7-2 Recommended manufacturers and models of EMC filters & AC Input Reactor & AC Output Reactor AC Drive Model Rated Input Current SSI707G43A SSI715G43A SSI722G43A 3.4A 5A 5.8A AC Input Filter Model AC Input Reactor Model Three-phase 380~440V 50/60HZ NFI-005 ACL-0005 NFI-005 ACL-0007 NFI-010 ACL-0007 Rated Output Current AC Output Reactor Model 2.1A 3.8A 5.1A OCL-0005 OCL-0005 OCL-0007 www.ssinverter.info SSI700 User Manual EMC 7.4 Shielded Cable 7.4.1 Requirements for Shielded Cable The shielded cable must be used to satisfy the EMC requirements of CE marking. Shielded cables are classified into three-conductor cable and four-conductor cable. If conductivity of the cable shield is not sufficient, add an independent PE cable, or use a four-conductor cable, of which one phase conductor is PE cable. The three-conductor cable and four-conductor cable are shown in the following figure. To suppress emission and conduction of the radio frequency interference effectively, the shield of the shielded cable is cooper braid. The braided density of the cooper braid should be greater than 90% to enhance the shielding efficiency and conductivity, as shown in the following figure. The following figure shows the grounding method of the shielded cable. Figure 7-1 Grounding of the shielded cable The installation precautions are as follows: • Symmetrical shielded cable is recommended. The four-conductor shielded cable can also be used as an input cable. • The motor cable and PE shielded conducting wire (twisted shielded) should be as short as possible to reduce electromagnetic radiation and external stray current and capacitive current of the cable. If the motor cable is over 100 meters long, an output filter or reactor is required. • It is recommended that all control cables be shielded. • It is recommended that a shielded cable be used as the output power cable of the AC drive; the cable shield must be well grounded. For devices suffering from interference, shielded twisted pair (STP) cable is recommended as the lead wire and the cable shield must be well grounded www.ssinverter.info SSI700 User Manual EMC 7.4.2 Cabling Requirements 1) The motor cables must be laid far away from other cables. The motor cables of several AC drives can be laid side by side. 2) It is recommended that the motor cables, power input cables and control cables be laid in different ducts. To avoid electromagnetic interference caused by rapid change of the output voltage of the AC drive, the motor cables and other cables must not be laid side by side for a long distance. 3) If the control cable must run across the power cable, make sure they are arranged at an angle of close to 90°. Other cables must not run across the AC drive. 4) The power input and output cables of the AC drive and weak-current signal cables (such as control cable) should be laid vertically (if possible) rather than in parallel. 5) The cable ducts must be in good connection and well grounded. Aluminium ducts can be used to improve electric potential. 6) The filter, AC drive and motor should be connected to the system (machinery or appliance) properly, with spraying protection at the installation part and conductive metal in full contact. Figure 7-2 Cabling diagram www.ssinverter.info SSI700 User Manual EMC 7.5 Solutions to Common EMC Interference Problems The AC drive generates very strong interference. Although EMC measures are taken, the interference may still exist due to improper cabling or grounding during use. When the AC drive interferes with other devices, adopt the following solutions. Interference Type Leakage protection switch tripping AC drive interference during running Communication interference I/O interference Solution • Connect the motor housing to the PE of the AC drive. • Connect the PE of the AC drive to the PE of the mains power supply. • Add a safety capacitor to the power input cable. • Add magnetic rings to the input drive cable. • Connect the motor housing to the PE of the AC drive. • Connect the PE of the AC drive to the PE of the mains voltage. • Add a safety capacitor to the power input cable and wind the cable with magnetic rings. • Add a safety capacitor to the interfered signal port or wind the signal cable with magnetic rings. • Connect the equipment to the common ground. • Connect the motor housing to the PE of the AC drive. • Connect the PE of the AC drive to the PE of the mains voltage. • Add a safety capacitor to the power input cable and wind the cable with magnetic rings. • Add a matching resistor between the communication cable source and the load side. • Add a common grounding cable besides the communication cable. • Use a shielded cable as the communication cable and connect the cable shield to the common grounding point. • Enlarge the capacitance at the low-speed DI. A maximum of 0.11uF capacitance is suggested. • Enlarge the capacitance at the AI. A maximum of 0.22 uF is Suggested. www.ssinverter.info Selection and Dimensions SSI700 User Manual Selection and Dimensions Chapter 8 Selection and Dimensions 8.1 Electrical Specifications of the SSI700 Table 8-1 Models and technical data of the SSI700 AC Drive Model Power Capacity (kVA) SSI704G23A SSI707G23A SSI715G23A 0.7 1.5 3 SSI707G43A SSI715G43A SSI722G43A 1.5 3 4 Rated Rated Adaptable Input Output Motor Current Current (KW, HP) Three-phase 220V 50/60HZ 3.4A 2.1A 0.4KW 0.5HP 5A 3.8A 0.75 KW 1 HP 5.8A 5.1A 1.5 KW 2 HP Three-phase 380V 50/60HZ 3.4A 2.1A 0.75 KW 1 HP 5A 3.8A 1.5 KW 2 HP 5.8A 5.1A 2.2 KW 3 HP Thermal Power Consumption (kW) 0.027 0.050 0.066 0.027 0.050 0.066 8.2 Physical Appearance and Overall Dimensions of the SSI700 Figure 8-1 Physical appearance and overall dimensions of the SSI700 (plastic housing) www.ssinverter.info SSI700 User Manual Selection and Dimensions 8.3 Physical Dimensions of External Operation Panel Figure 8-3 Physical dimensions of external operation panel www.ssinverter.info SSI700 User Manual Selection and Dimensions 8.4 Selection of Braking Unit and Braking Resistor 8.4.1 Physical Dimensions of External Braking Resistor The motor and load's regenerative energy is almost completely consumed on the braking resistor when braking. According to the formula U x U/R = Pb: • U refers to the braking voltage at system stable braking. Different systems select different braking voltages. The 380 VAC system usually selects 700 V braking voltage. • Pb refers to the braking power. 8.3.2 Selection of Power of Braking Resistor In theory, the power of the braking resistor is consistent with the braking power. But in consideration that the de-rating is 70%, you can calculate the power of the braking resistor according to the formula 0.7 x Pr = Pb x D. • Pr refers to the power of resistor. • D refers to the braking frequency (percentage of the regenerative process to the whole working process) Application Elevator Winding and unwinding Centrifuge Occasional braking load General application Braking Frequency 20%–30% 20%–30% 50%–60% 5% 10% Table 8-4 below provides data for reference. You can select different resistance and power based on actual needs. However, the resistance must not be lower than the recommended value. The power may be higher than the recommended value. The braking resistor model is dependent on the generation power of the motor in the actual system and is also related to the system inertia, deceleration time and potential energy load. For systems with high inertia, and/or rapid deceleration times, or frequent braking sequences, the braking resistor with higher power and lower resistance value should be selected.

Therefore, it is necessary to carry out routine and periodic maintenance. Routine maintenance involves checking: • Whether the motor sounds abnormally during running • Whether the motor vibrates excessively during running • Whether the installation environment of the AC drive changes. • Whether the AC drive's cooling fan works normally • Whether the AC drive overheats Routine cleaning involves: • Keep the AC drive clean all the time. • Remove the dust, especially metal powder on the surface of the AC drive, to prevent the dust from entering the AC drive. • Clear the oil stain on the cooling fan of the AC drive. 9.1.2 Periodic Inspection Perform periodic inspection in places where inspection is difficult. Periodic inspection involves: Check and clean the air duct periodically. Check whether the screws become loose. Check whether the AC drive is corroded. Check whether the wiring terminals show signs of arcing; Main circuit insulation test Prompt Before measuring the insulating resistance with megameter (500 VDC megameter recommended), disconnect the main circuit from the AC drive. Do not use the insulating resistance meter to test the insulation of the control circuit. The high voltage test need not be performed again because it has been completed before delivery. 9.1.3 Replacement of Vulnerable Components The vulnerable components of the AC drive are cooling fan and filter electrolytic capacitor. Their service life is related to the operating environment and maintenance status. Generally, the service life is shown as follows: Component Fan Service Life Possible Damage Reason 2 to 3 years • Bearing worn • Blade aging Judging Criteria • Whether there is crack on the blade • Whether there is abnormal vibration noise upon startup www.ssinverter.info SSI700 User Manual Component Service Life Electrolytic capacitor 4 to 5 years Maintenance and Troubleshooting Possible Damage Reason • Input power supply in poor quality • High ambient temperature • Frequent load jumping • Electrolytic aging Judging Criteria • Whether there is liquid leakage. • Whether the safe valve has projected. • Measure the static capacitance. • Measure the insulating resistance. 9.1.4 Storage of the AC Drive For storage of the AC drive, pay attention to the following two aspects: 1) Pack the AC drive with the original packing box provided by SSINVERTER. 2) Long-term storage degrades the electrolytic capacitor. Thus, the AC drive must be energized once every 2 years, each time lasting at least 5 hours. The input voltage must be increased slowly to the rated value with the regulator. 9.2 Warranty Agreement 1) Free warranty only applies to the AC drive itself. 2) SSINVERTER will provide 18-month warranty (starting from the leave-factory date as indicated on the barcode) for the failure or damage under normal use conditions. If the equipment has been used for over 18 months, reasonable repair expenses will be charged. 3) Reasonable repair expenses will be charged for the damages due to the following causes: • Improper operation without following the instructions • Fire, flood or abnormal voltage. • Using the AC drive for non-recommended function 4) The maintenance fee is charged according to SSINVERTER'S uniform standard. If there is an agreement, the agreement prevails. 9.3 Faults and Solutions The SSI700 provides a total of 24 pieces of fault information and protective functions. After a fault occurs, the AC drive implements the protection function, and displays the fault code on the operation panel (if the operation panel is available). Before contacting SSINVERTER for technical support, you can first determine the fault type, analyze the causes, and perform troubleshooting according to the following tables. If the fault cannot be rectified, contact the agent or SSINVERTER. EH is the AC drive hardware overcurrent or overvoltage signal. In most situations, hardware overvoltage fault causes EH.
