4. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and

W/T3 directly to the AC mains circuit power supply.

5. Ground the VFD-EL using the ground terminal. The grounding method must comply with the laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring

Diagram.

6. VFD-EL series is used only to control variable speed of 3-phase induction motors, NOT for 1phase motors or other purpose.

7. VFD-EL series shall NOT be used for life support equipment or any life safety situation.



WARNING!

1. DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-voltage.

2. There are highly sensitive MOS components on the printed circuit boards. These components are especially sensitive to static electricity. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

3. Only qualified persons are allowed to install, wire and maintain AC motor drives.

CAUTION!

1. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight, high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles.

RFI Jumper

RFI Jumper: The AC motor drive may emit the electrical noise. The RFI jumper is used to suppress the interference (Radio Frequency Interference) on the power line.

Main power isolated from earth:

If the AC motor drive is supplied from an isolated power (IT power), the RFI jumper must be cut off.

Then the RFI capacities (filter capacitors) will be disconnected from ground to prevent circuit damage

(according to IEC 61800-3) and reduce earth leakage current.

CAUTION!

1. After applying power to the AC motor drive, do not cut off the RFI jumper. Therefore, please make sure that main power has been switched off before cutting the RFI jumper.

2. The gap discharge may occur when the transient voltage is higher than 1,000V. Besides, electro-magnetic compatibility of the AC motor drives will be lower after cutting the RFI jumper.

3. Do NOT cut the RFI jumper when main power is connected to earth.

4. The RFI jumper cannot be cut when Hi-pot tests are performed. The mains power and motor must be separated if high voltage test is performed and the leakage currents are too high.

5. To prevent drive damage, the RFI jumper connected to ground shall be cut off if the AC motor drive is installed on an ungrounded power system or a high resistance-grounded

(over 30 ohms) power system or a corner grounded TN system.

CAUTION!

1. The wiring of main circuit and control circuit should be separated to prevent erroneous actions.

2. Please use shield wire for the control wiring and not to expose the peeled-off net in front of the terminal.

3. Please use the shield wire or tube for the power wiring and ground the two ends of the shield wire or tube.

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

5. The AC motor drive, motor and wiring may cause interference. To prevent the equipment damage, please take care of the erroneous actions of the surrounding sensors and the equipment.

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-EL 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-EL 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. Ensure there are no ground

loops.

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. For specific GFCI of the AC motor drive, please select a current sensor with sensitivity of 30mA or above.

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)

The factory setting of the operation direction is forward running. The method to control the operation direction is to set by the communication parameters. Please refer to the group 9 for details.

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 [+, -] for connecting brake resistor

All VFD-EL series don’t have a built-in brake chopper. Please connect an external

optional brake unit (BUE-series) and brake resistor. Refer to BUE series user manual for details.

Analog inputs (AVI, ACM)

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 ACM can bring improvement.

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

μ

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

AVI

C

ACM ferrite core

wind each wires 3 times or more around the core

Digital inputs (MI1~MI6, DCM)

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

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.

With Auto acceleration / deceleration it is possible to reduce vibration and shocks during starting/stopping the load.

During Auto acceleration the torque is automatically measured and the drive will accelerate to the set frequency with the fastest acceleration time and the smoothest starting current.

During Auto deceleration, regenerative energy is measured and the motor is smoothly stopped with the fastest deceleration time.

But when this parameter is set to 4, the actual accel/decel time will be equal to or more than parameter Pr.01.09 ~Pr.01.12.

Auto acceleration/deceleration makes the complicated processes of tuning unnecessary. It makes operation efficient and saves energy by acceleration without stall and deceleration without brake resistor.

In applications with brake resistor or brake unit, Auto deceleration shall not be used.

The parameter determines how the motor is stopped when the AC motor drive receives a valid stop command or detects External Fault.

Ramp:

Coast: the AC motor drive decelerates to Minimum Output Frequency (Pr.01.05) according to the deceleration time and then stops. the AC motor drive stops the output instantly upon command, and the motor free runs until it comes to a complete standstill.

The motor stop method is usually determined by the characteristics of the motor load and how frequently it is stopped.

(1)

(2)

It is recommended to use “ramp to stop” for safety of personnel or to prevent material from being wasted in applications where the motor has to stop after the drive is stopped. The deceleration time has to be set accordingly.

If motor free running is allowed or the load inertia is large, it is recommended to select “coast to stop”. For example: blowers, punching machines, centrifuges and pumps.

From the table, we see that the PWM carrier frequency has a significant influence on the electromagnetic noise, AC motor drive heat dissipation, and motor acoustic noise.

The PWM carrier frequency will be decreased automatically by the ambient temperature and output current of the AC motor drives. It is used to prevent AC motor drive overheat and extend IGBT’s life. Therefore, it is necessary to have this kind of protection method. Take an example of 460V models, assume that the carrier frequency is 12kHz, ambient temperature is

50 degrees C with single AC motor drive. If the output current exceeds 80% * rated current, the AC motor drive will decrease the carrier frequency automatically by the following chart. If output current is around 100% * rated current, the carrier frequency will decrease from 12k Hz to 8k Hz.

Analog Output Gain

Settings 1 to 200%

Unit: 1

Factory Setting: 100

This parameter sets the voltage range of the analog output signal AFM.

When Pr.03.03 is set to 0, the analog output voltage is directly proportional to the output frequency of the AC motor drive. With Pr.03.04 set to 100%, the Maximum Output Frequency

(Pr.01.00) of the AC motor drive corresponds to +10VDC on the AFM output.

Similarly, if Pr.03.03 is set to 1, the analog output voltage is directly proportional to the output current of the AC drive. With Pr.03.04 set to 100%, then 2.5 times the rated current corresponds to +10VDC on the AFM output.

NOTE

Any type of voltmeter can be used. If the meter reads full scale at a voltage less than 10V, Pr.

03.04 should be set using the following formula:

Pr. 03.04 = ((meter full scale voltage)/10) x 100%


CALL NOW 800-985-6929

When momentary power loss is detected, the AC motor drive will block its output and then wait for a specified period of time (determined by Pr.08.07, called Base-Block Time) before resuming operation. This parameter should be set at a value to ensure that any residual regeneration voltage from the motor on the output has disappeared before the drive is activated again.

This parameter also determines the waiting time before resuming operation after External

Baseblock and Auto Restart after Fault (Pr.08.15).

Current Limit for Speed Search Unit: 1

Settings 30 to 200% Factory Setting: 150

Following a momentary power loss, the AC motor drive will start its speed search operation only if the output current is greater than the value set by Pr.08.08. When the output current is less than the value of Pr.08.08, the AC motor drive output frequency is at “speed synchronization point”. The drive will start to accelerate or decelerate back to the operating frequency at which it was running prior to the power loss.

Factory Setting: 0

Only after an over-current OC or over-voltage OV fault occurs, the AC motor drive can be reset/restarted automatically up to 10 times.

Setting this parameter to 0 will disable automatic reset/restart operation after any fault has occurred.

When enabled, the AC motor drive will restart with speed search, which starts at the frequency before the fault. To set the waiting time before restart after a fault, please set Pr. 08.07 Base

Block Time for Speed Search.

This parameter should be used in conjunction with Pr.08.15.

For example: If Pr.08.15 is set to 10 and Pr.08.16 is set to 600s (10 min), and if there is no fault for over 600 seconds from the restart for the previous fault, the auto reset times for restart after fault will be reset to 10.

The rated voltage of the motor is usually 230V/200VAC 50Hz/60Hz and the input voltage of the AC motor drive may vary between 180V to 264 VAC 50Hz/60Hz. Therefore, when the AC motor drive is used without AVR function, the output voltage will be the same as the input voltage. When the motor runs at voltages exceeding the rated voltage with 12% - 20%, its lifetime will be shorter and it can be damaged due to higher temperature, failing insulation and unstable torque output.

AVR function automatically regulates the AC motor drive output voltage to the Maximum

Output Voltage (Pr.01.02). For instance, if Pr.01.02 is set at 200 VAC and the input voltage is at 200V to 264VAC, then the Maximum Output Voltage will automatically be reduced to a maximum of 200VAC.

When the motor ramps to stop, the deceleration time is longer. When setting this parameter to

2 with auto acceleration/deceleration, the deceleration will be quicker.

CRC CHK High

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 16-bit CRC register, putting the result in the CRC register.

Step 3: Examine the LSB of CRC register.

Step 4: If the LSB of CRC register is 0, shift the CRC register one bit to the right with MSB zero filling, then repeat step 3. If the LSB of CRC register is 1, shift the CRC register one bit to the right with MSB zero filling, Exclusive OR the CRC register with the polynomial value

A001H, then repeat step 3.

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 step 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 are 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.

4-92

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

Unsigned char* data Å a pointer to the message buffer

Unsigned char length Å 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++;

3.6 Exception response:

The AC motor drive is expected to return a normal response after receiving command messages from the master device. The following depicts the conditions when no normal response is replied to the master device.

The AC motor drive does not receive the messages due to a communication error; thus, the

AC motor drive has no response. The master device will eventually process a timeout condition.

The AC motor drive receives the messages without a communication error, but cannot handle them. An exception response will be returned to the master device and an error message

“CExx” will be displayed on the keypad of AC motor drive. The xx of “CExx” is a decimal code equal to the exception code that is described below.

In the exception response, the most significant bit of the original command code is set to 1, and an exception code which explains the condition that caused the exception is returned.

Factory Setting: 0

Factory Setting: 0

Note that the measured variable (feedback) controls the output frequency (Hz). Select input terminal accordingly. Make sure this parameter setting does not conflict with the setting for

Pr.10.00 (Master Frequency).

When Pr.10.00 is set to 2 or 3, the set point (Master Frequency) for PID control is obtained from the AVI or ACI external terminal (0 to +10V or 4-20mA) or from multi-step speed. When

Pr.10.00 is set to 1, the set point is obtained from the keypad.

Negative means:

Positive feedback means: -target value + feedback.

10.11

Source of PID Set point


Unit: 0.01


This parameter is used in conjunction with Pr.10.00 set 4 to input a set point in Hz.

10.02

Proportional Gain (P) Unit: 0. 1

Settings 0.0 to 10.0 Factory Setting: 1.0

This parameter specifies proportional control and associated gain (P). If the other two gains (I and D) are set to zero, proportional control is the only one effective. With 10% deviation (error) and P=1, the output will be P x10% x Master Frequency.

4-100

CALL NOW 800-985-6929





When P is greater than 1, it will decrease the deviation and get the faster response speed. But if setting too large value in Pr.10.02, it may cause the increased deviation during the stable area.

NOTE

The parameter can be set during operation for easy tuning.

10.03

Integral Time ( I )


Unit: 0.01


This parameter specifies integral control (continual sum of the deviation) and associated gain

(I). When the integral gain is set to 1 and the deviation is fixed, the output is equal to the input

(deviation) once the integral time setting is attained.

It can use integral time to eliminate the deviation during the stable area. If setting too large value in Pr.10.03, it may cause lower system response.

NOTE


10.04

Derivative Control (D)


Unit: 0.01


This parameter specifies derivative control (rate of change of the input) and associated gain

(D). With this parameter set to 1, the PID output is equal to differential time x (present deviation

− previous deviation). It increases the response speed but it may cause overcompensation.

NOTE


10.05

Upper Bound for Integral Control Unit: 1



CALL NOW 800-985-6929




This parameter defines an upper bound or limit for the integral gain (I) and therefore limits the

When the deviation is less than Pr.10.22 (in the range of PID set point to Pr.10.22 X PID set point) for a time exceeding the setting of Pr.10.23, the AC motor drive will decelerate to stop to be constant pressure status (This deceleration time is the setting of Pr.01.12). The system will be ready when the deviation is within the range of PID set point to Pr.10.22 X PID set point during deceleration.

CALL NOW 800-985-6929





Example: suppose that the set point of constant pressure control of a pump is 4kg, Pr.10.22 is set to 5%, Pr.10.23 is set to 15 seconds. It means that deviation is 0.2kg (4kgX5%=0.2kg), i.e. when feedback value is higher than 3.8kg for a time exceeding 15 seconds, the AC motor drive will decelerate to stop (this deceleration time will act according to Pr.01.12). When the feedback value is less than 3.8kg, the AC motor drive will start to run.

Pr.10.26 is set to 0.5 seconds. It means that offset is 0.2kg (4kgX5%=0.2kg), i.e. when feedback value is higher than 3.8kg for a time exceeding 15 seconds, the AC motor drive will decelerate to stop (this deceleration time will act according to Pr.01.12). When the feedback value is less than 3.8kg, the AC motor drive will start to run.

Status 1: Suppose that the AC motor drive is in the constant pressure status and the feedback change value is less than 0.12kg within 0.5 seconds. The AC motor drive won’t run until the feedback value is decreased by this proportion to the value less than 3kg.

Status 2: When the AC motor drive is in constant pressure, it won’t run until the feedback change value is less than 3.88kg (4-4kgX3%=3.88kg) for a time exceeding 0.5 seconds.

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-EL can have a built-in 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.


CALL NOW 800-985-6929



Chapter 5


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.

3. Check the wiring connections between the AC motor drive and motor for possible short circuits, also to ground.

4. Check for loose contacts between AC motor drive and motor. the

6. Check for possible excessive loading conditions at the motor.

7. If there are still any abnormal conditions when operating the AC motor drive after a shortcircuit is removed and the other points above are checked, it should be sent back to manufacturer.

Over voltage

The DC bus voltage has exceeded its maximum allowable value.

1. Check if the input voltage falls within the rated AC motor drive input voltage range.

2. Check for possible voltage transients.

3. DC-bus over-voltage may also be caused by motor regeneration. Either increase the

Decel. Time or add an optional brake resistor

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 by measuring the voltage between ~ . It should be less than 25VDC.

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. Definition for Brake Usage ED%

Explanation: The definition of the barke 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 brake torque would decrease accordingly. Suggested cycle time is one minute

9. 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 brake 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.

Application 1

Question

When more than one AC motor drive is connected to the same mains power, and one of them is ON during operation.

When applying power to one of the AC motor drive, the charge current of the capacitors may cause voltage dip. The AC motor drive may be damaged when over current occurs during operation.

Application 3 Question

Used to improve the input power factor, to reduce harmonics and provide protection from

AC line disturbances. (surges, switching spikes, short interruptions, etc.). The AC line reactor should be installed when the power supply capacity is 500kVA or more and exceeds 6 times the inverter capacity, or the mains wiring distance

≤

10m.

When the mains power capacity is too large, line impedance will be small and the charge current will be too high. This may damage AC motor drive due to higher rectifier temperature.

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 brake 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

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:

40%

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).

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.

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

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.
