6. When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor terminals

U/T1, V/T2, and W/T3, respectively. To permanently reverse the direction of motor rotation, switch over any of the two motor leads.

7. With long motor cables, high capacitive switching current peaks can cause over-current, high leakage current or lower current readout accuracy. To prevent this, the motor cable should be less than 20m for 3.7kW models and below. And the cable should be less than 50m for 5.5kW models and above. For longer motor cables use an AC output reactor.

8. The AC motor drive, electric welding machine and the greater horsepower motor should be grounded separately.

9. Use ground leads that comply with local regulations and keep them as short as possible.

10. No brake resistor is built in the VFD-M series, it can install brake resistor for those occasions that use higher load inertia or frequent start/stop. Refer to Appendix B for details.

11. Multiple VFD-M units can be installed in one location. All the units should be grounded directly to a common ground terminal, as shown in the figure below.

CAUTION!

Mains power terminals (R/L1, S/L2, T/L3)

 Connect these terminals (R/L1, S/L2, T/L3) via a non-fuse breaker or earth leakage breaker to

3-phase AC power (some models to 1-phase AC power) for circuit protection. It is unnecessary to consider phase-sequence.

 It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off power quickly and reduce malfunction when activating the protection function of AC motor drives. Both ends of the MC should have an R-C surge absorber.

 Please make sure to fasten the screw of the main circuit terminals to prevent sparks which is made by the loose screws due to vibration.





 Please use voltage and current within the regulation shown in Appendix A.

 When using a GFCI (Ground Fault Circuit Interrupter), select a current sensor with sensitivity of

200mA, and not less than 0.1-second detection time to avoid nuisance tripping.

 Do NOT run/stop AC motor drives by turning the power ON/OFF. Run/stop AC motor drives by

RUN/STOP command via control terminals or keypad. If you still need to run/stop AC drives by turning power ON/OFF, it is recommended to do so only ONCE per hour.

 Do NOT connect 3-phase models to a 1-phase power source.

Output terminals for main circuit (U, V, W)

 When it needs to install the filter at the output side of terminals U/T1, V/T2, W/T3 on the AC motor drive. Please use inductance filter. Do not use phase-compensation capacitors or L-C

(Inductance-Capacitance) or R-C (Resistance-Capacitance), unless approved by Delta.

 DO NOT connect phase-compensation capacitors or surge absorbers at the output terminals of

AC motor drives.

 Use well-insulated motor, suitable for inverter operation.

Terminals [B1, B2] for connecting external brake unit

Brake Resistor(optional)

Refer to Appendix B for the use of special brake resistor

BR

B2



Connect a brake resistor or brake unit in applications with frequent deceleration ramps, short deceleration time, too low braking torque or requiring increased braking torque.



The AC motor drive has a built-in brake chopper, you can connect the external brake resistor to the terminals [B1, B2] when needed.



When not used, please leave the terminals [B1, B2] open.

Note:

Use twisted-shielded, twisted-pair or shielded-lead wires for the control signal wiring. It is recommended to run all signal wiring in a separate steel conduit. The shield wire should only be connected at the drive. Do not connect shield wire on both ends.

Analog inputs (AVI, ACI)

 Analog input signals are easily affected by external noise. Use shielded wiring and keep it as short as possible (<20m) with proper grounding. If the noise is inductive, connecting the shield to terminal GND can bring improvement.

 If the analog input signals are affected by noise from the AC motor drive, please connect a capacitor (0.1



F and above) and ferrite core as indicated in the following diagrams:

AVI/ACI

C

GND ferrite core

wind each wires 3 times or more around the core

Digital inputs (M0~M5)

 When using contacts or switches to control the digital inputs, please use high quality components to avoid contact bounce.

Digital outputs (MO1)

 Make sure to connect the digital outputs to the right polarity, see wiring diagrams.

 When connecting a relay to the digital outputs, connect a surge absorber or fly-back diode across the coil and check the polarity.





General

 Keep control wiring as far away as possible from the power wiring and in separate conduits to avoid interference. If necessary let them cross only at 90º angle.

 The AC motor drive control wiring should be properly installed and not touch any live power wiring or terminals.

NOTE

 If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.

DANGER!

Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it comes in contact with high voltage.

In the below diagram, suppose the Maximum Output Frequency is 60 Hz (Master Freq),

Minimum Output Frequency (start-up) is 1.0 Hz, and accel/decel time 1 is 10 seconds. The actual time for the AC drive to accelerate from start-up to 60 Hz is 9.83 seconds (deceleration time is also 9.83 seconds), can be determined by the formula.

The absence of a decimal point indicates a four-digit integer.

A signal decimal point between the middle and the right-most numbers is a true decimal point. For example, the number 123.4 would be displayed as “123.4”.

9999.

A single decimal point after the right-most number is not a true decimal point; instead it indicates that a zero follows the right-most number. For example, the number 12340 would be displayed as “1234.”

999.9.

Two decimal points (one between the middle and the right-most numbers, and one after the right-most number) are not true decimal points; instead they indicate that two zeros follow the right-most number. For example, the number 345600 would be displayed as “345.6.”.

CRC (Cyclical Redundancy Check) is calculated by the following steps:

Step 1: Load a 16-bit register (called CRC register) with FFFFH.

Step 2: Exclusive OR the first 8-bit byte of the command message with the low order byte of the 16bit CRC register, putting the result in the CRC register.

Step 3: Shift the CRC register one bit to the right with MSB zero filling. Extract and examine the LSB.

Step 4: If the LSB of CRC register is 0, repeat step 3, else Exclusive or the CRC register with the polynomial value A001H.

Step 5: Repeat step 3 and 4 until eight shifts have been performed. When this is done, a complete

8-bit byte will have been processed.

Step 6: Repeat steps 2 to 5 for the next 8-bit byte of the command message.

Continue doing this until all bytes have been processed. The final contents of the CRC register is the

CRC value.

When transmitting the CRC value in the message, the upper and lower bytes of the

CRC value must be swapped, i.e. the lower order byte will be transmitted first.

The following is an example of CRC generation using C language. The function takes two arguments:

Unsigned char* data  a pointer to the message buffer

Unsigned char length  the quantity of bytes in the message buffer

The function returns the CRC value as a type of unsigned integer.

Unsigned int crc_chk(unsigned char* data, unsigned char length){

int j;

unsigned int reg_crc=0xFFFF;





while(length--){

reg_crc ^= *data++;

for(j=0;j<8;j++){

if(reg_crc & 0x01){ /* LSB(b0)=1 */

reg_crc=(reg_crc>>1) ^ 0xA001;

}else{

reg_crc=reg_crc >>1;

}

}

}

return reg_crc;

}

(Please refer to Accel/Decel time setting at parameter Pr.10-Pr.13)

 When this parameter is set to 03, the AC drive will accel/decel in the fastest and smoothest possible way by automatically adjusting the accel /decel time.

 This parameter provides five modes to choose:

00 Linear acceleration and deceleration (operation by Pr.10, Pr.11, or Pr.12, Pr.13 acceleration/deceleration time)

 AVR function automatically regulates the AC drive output voltage to the Maximum Output

Voltage (Pr.03). For instance, if Pr.03 is set at 200 VAC and the input voltage varies from

200V to 264VAC, then the Maximum Output Voltage will automatically be regulated to 200VAC.

 When the AVR function is disabled, the Maximum Output Voltage follows the variations of the input voltage (180V to 264VAC).

 Selecting program value 2 enables the AVR function and also disables the AVR function during deceleration. This offers a quicker deceleration.

One-Time Delay


Unit: 0.1sec


 PI Control: When controlled by P action only, deviations cannot be eliminated entirely. To eliminate residual deviations, the P + I control is generally utilized. If PI is used, it could eliminate the deviation caused by set-point changes and external interferences. However, if the I-action is excessively powerful, it will delay the response to the variation. The P-action could solely be used on a loading system that possesses integral components.

 PD Control: when a deviation occurs, the system immediately generates some operational load that is greater than the single load generated by the D-action in order to restrain the increment of the deviation. If the deviation is small, the effectiveness of the P-action decreases as well. In some cases, control systems include integral component loads, which are controlled by the P action only, and sometimes, if the integral component is functioning, the whole system will be vibrating. In such cases, a PD control could be used to lower the Paction’s vibration and to stabilize the system. In other words, this control is good for use if the loads have no braking functions over the process.

 PID Control: Uses the I-action to eliminate the deviation and the D-action to restrain the vibration, and combine with the P action to construct the PID control. The PID control method normally determines a control process with no deviations, high accuracy and very stable.

5.13 Electromagnetic/Induction Noise




Many sources of noise surround AC motor drives and penetrate it by radiation or conduction. It may cause malfunctioning of the control circuits and even damage the AC motor drive. Of course, there are solutions to increase the noise tolerance of an AC motor drive. But this has its limits. Therefore, solving it from the outside as follows will be the best.

1. Add surge suppressor on the relays and contacts to suppress switching surges.

2. Shorten the wiring length of the control circuit or serial communication and keep them separated from the power circuit wiring.

3. Comply with the wiring regulations by using shielded wires and isolation amplifiers for long length.

4. The grounding terminal should comply with the local regulations and be grounded independently, i.e. not to have common ground with electric welding machines and other power equipment.

5. Connect a noise filter at the mains input terminal of the AC motor drive to filter noise from the power circuit. VFD-M can have a filter as option.

In short, solutions for electromagnetic noise exist of “no product”(disconnect disturbing equipment),

“no spread”(limit emission for disturbing equipment) and “no receive”(enhance immunity).

5.14 Environmental Condition

Since the AC motor drive is an electronic device, you should comply with the environmental conditions. Here are some remedial measures if necessary.

1. To prevent vibration, the use of anti-vibration dampers is the last choice. Vibrations must be within the specification. Vibration causes mechanical stress and it should not occur frequently, continuously or repeatedly to prevent damage to the AC motor drive.

2. Store the AC motor drive in a clean and dry location, free from corrosive fumes/dust to prevent corrosion and poor contacts. Poor insulation in a humid location can cause shortcircuits. If necessary, install the AC motor drive in a dust-proof and painted enclosure and in particular situations, use a completely sealed enclosure.

3. The ambient temperature should be within the specification. Too high or too low temperature will affect the lifetime and reliability. For semiconductor components, damage will occur once any specification is out of range. Therefore, it is necessary to periodically check air quality and the cooling fan and provide extra cooling of necessary. In addition, the microcomputer may not work in extremely low temperatures, making cabinet heating necessary.





4. Store within a relative humidity range of 0% to 90% and non-condensing environment.

Use an air conditioner and/or exsiccator.

5.15 Affecting Other Machines

An AC motor drive may affect the operation of other machines due to many reasons. Some solutions are:

 High Harmonics at Power Side

High harmonics at power side during running can be improved by:

1. Separate the power system: use a transformer for AC motor drive.

2. Use a reactor at the power input terminal of the AC motor drive.

3. If phase lead capacitors are used (never on the AC motor drive output!!), use serial reactors to prevent damage to the capacitors damage from high harmonics. serial reactor phase lead capacitor

 Motor Temperature Rises

When the motor is a standard induction motor with fan, the cooling will be bad at low speeds, causing the motor to overheat. Besides, high harmonics at the output increases copper and core losses. The following measures should be used depending on load and operation range.

1. Use a motor with independent ventilation (forced external cooling) or increase the motor rated power.

2. Use a special inverter duty motor.

3. Do NOT run at low speeds for long time.


Chapter 6 Fault Code Information and Maintenance

6.1 Fault Code Information

The AC motor drive has a comprehensive fault diagnostic system that includes several different alarms and fault messages. Once a fault is detected, the corresponding protective functions will be activated. The following faults are displayed as shown on the AC motor drive digital keypad display.

2. Set external terminal to “RESET” (set one of Pr.39~Pr.42 to 05) and then set to be ON.

NOTE

Make sure that RUN command or signal is OFF before executing RESET to prevent damage or personal injury due to immediate operation.

6.2 Maintenance and Inspections

Modern AC motor drives are based on solid-state electronics technology. Preventive maintenance is required to keep the AC motor drive in its optimal condition, and to ensure a long life. It is recommended to have a qualified technician perform a check-up of the AC motor drive regularly.

Daily Inspection:

Basic check-up items to detect if there were any abnormalities during operation are:

1. Whether the motors are operating as expected.

2. Whether the installation environment is abnormal.

3. Whether the cooling system is operating as expected.

4. Whether any irregular vibration or sound occurred during operation.

5. Whether the motors are overheating during operation.

6. Always check the input voltage of the AC drive with a Voltmeter.

Periodic Inspection:

Before the check-up, always turn off the AC input power and remove the cover. Wait at least 10 minutes after all display lamps have gone out, and then confirm that the capacitors have fully discharged. It should be less than 25VDC.





DANGER!

2. Only qualified personnel can install, wire and maintain AC motor drives. Please take off any metal objects, such as watches and rings, before operation. And only insulated tools are allowed.

3. Never reassemble internal components or wiring.

4. Prevent static electricity.



NOTE

1. Please select the brake unit and/or brake resistor according to the table. “-“ means no

Delta product. Please use the brake unit according to the Equivalent Resistor Value.

2. If damage to the drive or other equipment is due to the fact that the brake resistors and the brake modules in use are not provided by Delta, the warranty will be void.

3. Take into consideration the safety of the environment when installing the brake resistors.

4. If the minimum resistance value is to be utilized, consult local dealers for the calculation of the power in Watt.

5. Please select thermal relay trip contact to prevent resistor over load. Use the contact to switch power off to the AC motor drive!

6. When using more than 2 brake units, equivalent resistor value of parallel brake unit can’t be less than the value in the column “Minimum Equivalent Resistor Value for Each AC

Drive” (the right-most column in the table).

7. Please read the wiring information in the user manual of the brake unit thoroughly prior to installation and operation.

8. In applications with brake resistor or brake unit, Pr.25 (Over-voltage stall prevention) must be disabled. And Pr.102 (AVR function) shall not be used.

9. Definition for Braking Usage ED%

Explanation: The definition of the barking usage ED(%) is for assurance of enough time for the brake unit and brake resistor to dissipate away heat generated by braking. When the brake resistor heats up, the resistance would increase with temperature, and braking torque would decrease accordingly. Suggest cycle time is one minute

100%

Braking Time

T1

Cycle Time

T0

ED% = T1/T0x100(%)

10. For safety reasons, install a thermal overload relay between brake unit and brake resistor.

Together with the magnetic contactor (MC) in the mains supply circuit to the drive it offers protection in case of any malfunctioning. The purpose of installing the thermal overload relay is to protect the brake resistor against damage due to frequent braking or in case the brake unit is continuously on due to unusual high input voltage. Under these circumstances the thermal overload relay switches off the power to the drive. Never let the thermal overload relay switch off only the brake resistor as this will cause serious damage to the AC Motor Drive.

Note 1:

The table above gives approximate wire size for the zero phase reactors but the selection is ultimately governed by the type and diameter of cable fitted i.e. the cable must fit through the center hole of zero phase reactors.

Note 2:

Only the phase conductors should pass through, not the earth core or screen.

Note 3:

When long motor output cables are used, an output zero phase reactor may be required to reduce radiated emissions from the cable.

If users are to operate the AC motor drive in coordination with the EMI filters manufactured by

DELTA, consult the above chart for the appropriate I/O terminals’ of the applicable filters.

!

The filter will cause high leakage current. We recommend the grounding is required.

Installation

All electrical equipment, including AC motor drives, will generate high-frequency/low-frequency noise and will interfere with peripheral equipment by radiation or conduction when in operation. By using an

EMI filter with correct installation, much interference can be eliminated. It is recommended to use

DELTA EMI filter to have the best interference elimination performance.

We assure that it can comply with following rules when AC motor drive and EMI filter are installed and wired according to user manual:

EN61000-6-4

EN61800-3: 1996 + A11: 2000

EN55011 (1991) Class A Group 1 (1 st

Environment, restricted distribution)

General precaution

1. EMI filter and AC motor drive should be installed on the same metal plate.

2. Please install AC motor drive on footprint EMI filter or install EMI filter as close as possible to the AC motor drive.

3. Please wire as short as possible.

4. Metal plate should be grounded.

5. The cover of EMI filter and AC motor drive or grounding should be fixed on the metal plate and the contact area should be as large as possible.





Choose suitable motor cable and precautions

Improper installation and choice of motor cable will affect the performance of EMI filter. Be sure to observe the following precautions when selecting motor cable.

1. Use the cable with shielding (double shielding is the best).

2. The shielding on both ends of the motor cable should be grounded with the minimum length and maximum contact area.

3. Remove any paint on metal saddle for good ground contact with the plate and shielding.



The length of motor cable

When motor is driven by an AC motor drive of PWM type, the motor terminals will experience surge voltages easily due to components conversion of AC motor drive and cable capacitance. When the motor cable is very long (especially for the 460V series), surge voltages may reduce insulation quality. To prevent this situation, please follow the rules below:

 Use a motor with enhanced insulation.

 Connect an output reactor (optional) to the output terminals of the AC motor drive

 The length of the cable between AC motor drive and motor should be as short as possible (10 to 20 m or less)

 For models 7.5hp/5.5kW and above:

Insulation level of motor

1000V

66 ft (20m)

1300V

328 ft (100m)

NOTE

 When a thermal O/L relay protected by motor is used between AC motor drive and motor, it may malfunction (especially for 460V series), even if the length of motor cable is only 165 ft

(50m) or less. To prevent it, please use AC reactor and/or lower the carrier frequency (Pr. 71

PWM carrier frequency).

 Never connect phase lead capacitors or surge absorbers to the output terminals of the AC motor drive.

 If the length is too long, the stray capacitance between cables will increase and may cause leakage current. It will activate the protection of over current, increase leakage current or not insure the correction of current display. The worst case is that AC motor drive may damage.

 If more than one motor is connected to the AC motor drive, the total wiring length is the sum of the wiring length from AC motor drive to each motor.

Appendix C How to Select the Right AC Motor Drive

The choice of the right AC motor drive for the application is very important and has great influence on its lifetime. If the capacity of AC motor drive is too large, it cannot offer complete protection to the motor and motor maybe damaged. If the capacity of AC motor drive is too small, it cannot offer the required performance and the AC motor drive maybe damaged due to overloading.

But by simply selecting the AC motor drive of the same capacity as the motor, user application requirements cannot be met completely. Therefore, a designer should consider all the conditions, including load type, load speed, load characteristic, operation method, rated output, rated speed, power and the change of load capacity. The following table lists the factors you need to consider, depending on your requirements.

C.2 General Precaution

Selection Note

1

、

When the AC Motor Drive is connected directly to a large-capacity power transformer

(600kVA or above) or when a phase lead capacitor is switched, excess peak currents may occur in the power input circuit and the converter section may be damaged. To avoid this, use an AC input reactor (optional) before AC Motor Drive mains input to reduce the current and improve the input power efficiency.

2

、

When a special motor is used or more than one motor is driven in parallel with a single

AC Motor Drive, select the AC Motor Drive current



1.25x(Sum of the motor rated currents).

3

、

The starting and accel./decel. characteristics of a motor are limited by the rated current and the overload protection of the AC Motor Drive. Compared to running the motor

D.O.L. (Direct On-Line), a lower starting torque output with AC Motor Drive can be expected. If higher starting torque is required (such as for elevators, mixers, tooling machines, etc.) use an AC Motor Drive of higher capacity or increase the capacities for both the motor and the AC Motor Drive.

4

、

When an error occurs on the drive, a protective circuit will be activated and the AC

Motor Drive output is turned off. Then the motor will coast to stop. For an emergency stop, an external mechanical brake is needed to quickly stop the motor.

Parameter Settings Note

1

、

The AC Motor Drive can be driven at an output frequency up to 400Hz (less for some models) with the digital keypad. Setting errors may create a dangerous situation. For safety, the use of the upper limit frequency function is strongly recommended.

2

、

High DC braking operating voltages and long operation time (at low frequencies) may cause overheating of the motor. In that case, forced external motor cooling is recommended.

3

、

Motor accel./decel. time is determined by motor rated torque, load torque, and load inertia.

4

、

If the stall prevention function is activated, the accel./decel. time is automatically extended to a length that the AC Motor Drive can handle. If the motor needs to



 decelerate within a certain time with high load inertia that can’t be handled by the AC

Motor Drive in the required time, either use an external brake resistor and/or brake unit, depending on the model, (to shorten deceleration time only) or increase the capacity for both the motor and the AC Motor Drive.

C.3 How to Choose a Suitable Motor

Standard motor

When using the AC Motor Drive to operate a standard 3-phase induction motor, take the following precautions:

1

、

The energy loss is greater than for an inverter duty motor.

2

、

Avoid running motor at low speed for a long time. Under this condition, the motor temperature may rise above the motor rating due to limited airflow produced by the motor’s fan. Consider external forced motor cooling.

3

、

When the standard motor operates at low speed for long time, the output load must be decreased.

4

、

The load tolerance of a standard motor is as follows:

Load duty-cycle

25%

40%

100

82

60%

70

60

50

continuous

0

3 6 20 60

Frequency (Hz)

5

、

If 100% continuous torque is required at low speed, it may be necessary to use a special inverter duty motor.

6

、

Motor dynamic balance and rotor endurance should be considered once the operating speed exceeds the rated speed (60Hz) of a standard motor.





7

、

Motor torque characteristics vary when an AC Motor Drive instead of commercial power supply drives the motor. Check the load torque characteristics of the machine to be connected.

8

、

Because of the high carrier frequency PWM control of the VFD series, pay attention to the following motor vibration problems:



Resonant mechanical vibration: anti-vibration (damping) rubbers should be



used to mount equipment that runs at varying speed.

Motor imbalance: special care is required for operation at 50 or 60 Hz and



higher frequency.

To avoid resonances, use the Skip frequencies.

9

、

The motor fan will be very noisy when the motor speed exceeds 50 or 60Hz.

Special motors:

1

、

Pole-changing (Dahlander) motor:

The rated current is differs from that of a standard motor. Please check before operation and select the capacity of the AC motor drive carefully. When changing the pole number the motor needs to be stopped first. If over current occurs during operation or regenerative voltage is too high, please let the motor free run to stop (coast).

2

、

Submersible

The rated current is higher than that of a standard motor. Please check before operation and choose the capacity of the AC motor drive carefully. With long motor cable between

AC motor drive and motor, available motor torque is reduced.

3

、

Explosion-proof (Ex) motor:

Needs to be installed in a safe place and the wiring should comply with the (Ex) requirements. Delta AC Motor Drives are not suitable for (Ex) areas with special precautions.

4

、

Gear reduction motor:

The lubricating method of reduction gearbox and speed range for continuous operation will be different and depending on brand. The lubricating function for operating long time at low speed and for high-speed operation needs to be considered carefully.

5

、

Synchronous

The rated current and starting current are higher than for standard motors. Please check before operation and choose the capacity of the AC motor drive carefully. When



 the AC motor drive operates more than one motor, please pay attention to starting and changing the motor.

Power Transmission Mechanism

Pay attention to reduced lubrication when operating gear reduction motors, gearboxes, belts and chains, etc. over longer periods at low speeds. At high speeds of 50/60Hz and above, lifetime reducing noises and vibrations may occur.

Motor torque

The torque characteristics of a motor operated by an AC motor drive and commercial mains power are different.
