PurPose of ac drives

AC drives are generally known by many different names: Adjustable Frequency Drives (AFD), Variable Frequency Drives (VFD), and Inverters. Drives are used primarily to vary the speed of three phase AC induction motors, and they also provide non-emergency start and stop control, acceleration and deceleration, and overload protection. By gradually accelerating the motor, drives can reduce the amount of motor startup inrush current.

AC drives function by converting incoming AC power to DC, which is then synthesized back into three phase output power. The voltage and frequency of this synthesized output power is directly varied by the drive, where the frequency determines the speed of the three phase AC induction motor.

Chapter 1: Getting Started

selecting the ProPer drive rating

a. deterMine Motor full-load aMPerage (fla)

Motor FLA is located on the nameplate of the motor.

NOTE: FLA of motors that have been rewound may be higher than stated.

b. deterMine Motor overload requireMents

Many applications experience temporary overload conditions due to starting requirements or impact loading. Most AC drives are designed to operate at 150% overload for 60 seconds. If the application requires an overload greater than 150% or longer than 60 seconds, the AC drive must be oversized.

NOTE: Applications that require replacement of existing motor starters with AC drives may require up to 600% overload.

c. installation altitude

AC drives rely upon the cooling properties of air for cooling. As the altitude increases, the air becomes less dense, and this decrease in air density decreases the cooling properties of the air. Therefore, the AC drive must be oversized to compensate for the decrease in cooling. Most AC drives are designed to operate at 100% capacity up to altitudes of 1000 meters. Above 1000m, the AC drive must be derated.

d. deterMine Max enclosure internal teMP

AC drives generate a significant amount of heat and will cause the internal temperature of an enclosure to exceed the rating of the AC drive, even when the ambient temperature is less than 104 °F (40 °C). Enclosure ventilation and/or cooling may be required to maintain a maximum internal temperature of 104 °F (40 °C) or less. Ambient temperature measurements/calculations should be made for the maximum expected temperature.

e. calculate required outPut aMPerage

Use the chart below to calculate the required FLA of the AC drive, as shown by the following examples. Select the rating that equals the motor’s voltage and equals or exceeds the calculated amperage.

•

Example 1 (GS1 or GS2 drive): Motor FLA = 6A; Overload = 200% @ 45s; Altitude = 800m; MEIT = 45°C

•

Example 2 (DURA Motor FLA = 8A; Overload = 135% @ 75s; Altitude = 1100m; MEIT = 35°C

If overload is < 150% and < 60 seconds 1

If overload is > 60 seconds (overload / 100)%

Overload Result Multiply FLA x overload entry 8.0 10.8

Altitude is < 1,000m 1

Altitude is > 1,000m and < 3,000m 1 + ((altitude - 1,000m) x 0�0001)

Altitude Result Multiply overload result x altitude entry 8.0 10.91

Maximum enclosure internal temperature (MEIT) is < 40°C

40°C < MEIT < 50° and GS1/2 AC drive up to 5hp

GS1 AC drives should be kept in their shipping carton or crate until they are installed. In order to retain their warranty coverage, they should be stored as described below if they are not to be installed and used within three months.

•

Store in a clean and dry location free from direct sunlight and corrosive fumes.

•

For storage of longer than 3 months, store within an ambient temperature range of -20°C to 30°C (-4°F to 86°F).

•

For storage of 3 months or less, store within an ambient temperature range of -20°C to 60°C (-4°F to 140°F).

•

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

•

Store within an air pressure range of 86 kPA to 106 kPA.

•

DO NOT store in an area with rapid changes in temperature. (It may cause condensation and frost.)

•

DO NOT place directly on the ground.

Ambient Conditions

NOTE: If the drive is stored or is otherwise unused for more than a year, the drive’s internal DC link capacitors should be recharged before use. Otherwise, the capacitors may be damaged when the drive starts to operate. We recommend recharging the capacitors of any unused drive at least once per year. (Refer to Chapter 6, “Maintenance and Troubleshooting” for information about recharging DC link capacitors.)

INsTAllATIoN

Fan

Motor

Install the AC drive in an enclosure that is specifically designed to house electrical and electronic control equipment. Provide proper spacing within the enclosure to allow the dissipation of heat produced by the drive and any other included electrical and electronic equipment. Ventilation or air conditioning may also be required, depending upon the application.

Improper installation of the AC drive will greatly reduce its life. Be sure to observe the following precautions when selecting a mounting location:

•

Do not mount the AC drive near heat-radiating elements or in direct sunlight.

•

Do not install the AC drive in a place subjected to high temperature, high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles.

•

Mount the AC drive vertically and do not restrict the air flow to the heat sink fins.

Warning: failure to observe these preCautions may damage the drive and void the Warranty!

Warning: aC drives generate a large amount of heat WhiCh may damage the aC drive. auxiliary Cooling

methods are typiCally required in order not to exCeed maximum ambient temperatures.

1) During installation, follow all local electrical, construction, and safety codes for the country in which the AC drive is to be installed.

2) Make sure the appropriate protective devices (circuit breaker or fuses) are connected between the power supply and AC drive.

3) Make sure that the leads are connected correctly and the AC drive is properly grounded.

4) Use ground leads that comply with AWG/MCM standards, and keep them as short as possible.

5) The use of contactors or disconnect switches for run/stop control of the AC drive and motor will

reduce the operating life cycle of the AC drive. Cycling a power circuit switching device while the AC drive is in run mode should be done only in emergency situations.

The installation of contactors or disconnects to isolate the motor during maintenance, though permissible, is not recommended. Opening contactors or disconnects while the drive is running will reduce the life cycle of the drive and may immediately damage the inverter section of the drive!

6) Multiple GS1 units can be installed in one location. All the units should be grounded directly to a common ground terminal. The GS1 ground terminals may also be connected in parallel, as shown in the figure below. Make sure there are no ground loops.

Chapter 2: Installation and Wiring

Correct Incorrect

Forward

7) When the AC drive output terminals T1, T2, and T3 are connected to the motor terminals T1, T2, and T3, respectively, the motor will rotate counterclockwise (as viewed from the shaft end of the motor) when a forward operation command is received. To reverse the direction of motor rotation, switch the connections of any of the two motor leads.

8) Make sure that the power source is capable of supplying the correct voltage and required current to the AC drive.

9) Do not attach or remove wiring when power is applied to the AC drive.

10) Do not monitor the signals on the circuit board while the AC drive is in operation.

11) For single-phase, 115V class AC drives, AC power must be connected to terminals L1 and L2. For the single-phase, 230V class AC drives, the AC power can be connected to any two of the three input terminals L1, L2, or L3.

NOTE: This AC drive is not intended for use with single-phase motors.

12) Route the power and control wires separately, or at 90 degree angle to each other.

13) When using a GFCI (Ground Fault Circuit Interrupt), select current sensor with sensitivity of 200mA, and not less than 0.1-second detection to avoid nuisance tripping.

Chapter 2: Installation and Wiring

Motor oPeration Precautions

1) When using the AC drive to operate a standard 3-phase induction motor, the energy loss is greater than for an inverter duty motor.

2) Avoid running a standard induction motor at low speed, which may cause the motor temperature to exceed the motor rating due to limited airflow produced by the motor’s fan.

3) When the standard motor operates at low speed, the output load must be decreased.

4) If 100% output torque is desired at low speed, it may be necessary to use a special “inverter-duty” rated motor.

Input fuses protect the AC drive from excessive input current due to line surges, short circuits, and ground faults. They are recommended for all installations and may be required for UL-listed installations.

3 Contactor (Optional)

Do NOT use a contactor or disconnect switch for run/stop control of the AC drive and motor. This will reduce the operating life

cycle of the AC drive. Cycling a power circuit switching device while the AC drive is in run mode should be done only in emergency situations.

4 AC Line Reactor – Input Side (Optional)

Input line reactors protect the AC drive from transient overvoltage conditions typically caused by utility capacitor switching. Input line reactors also reduce harmonics associated with AC drives, and are recommended for all installations.

5 RF Filter (Optional)

RF filters reduce the radio frequency interference or noise on the input or output side of the inverter.

6 AC Line Reactor – Output Side (Optional)

Output line (load) reactors protect the motor insulation against AC drive short circuits and IGBT reflective wave damage, and also “smooth” the motor current waveform, allowing the motor to run cooler. They are recommended for operating “non-inverter-

duty” motors, and when the length of wiring between the AC drive and motor exceeds 75ft.

Motor ParaMeters

P0.00 Motor Nameplate Voltage

Range: 115/230V series: 200/208/220/230/240 Default Setting: 240

This parameter determines the Maximum Output Voltage of the AC drive. The Maximum Output Voltage setting must be less than or equal to the rated voltage of the motor as indicated on the motor nameplate. The setting value must be equal to or greater than the Mid-Point Voltage (P2.05).

P0.01 Motor Nameplate Amps

Range: Drive Rated Amps x 0�3 to Drive Rated Amps x 1�0 Default Setting: Drive Rating (A)

This parameter sets the output current to the motor. The value is determined by the value found on the motor nameplate.

P0.02 Motor Base Frequency

Range: 50/60/400 Default Setting: 60

This value should be set according to the base frequency of the motor as indicated on the motor nameplate. It sets the Maximum Voltage Frequency and determines the volts per hertz ratio.

P0.03 Motor Base RPM

Range: 375 to 9999 rpm Default Setting: 1750

This value should be set according to rated Base RPM of the motor as indicated on the motor nameplate.

P0.04 Motor Maximum RPM

Range: P0�03 to 9999 rpm Default Setting: P0�03

•

This value should be set according to the desired maximum speed of the motor�

•

This value cannot be set lower than Motor Base RPM (P0�03)�

Warning: the motor maximum rpm parameter (p0.04) should never exCeed the maximum safe rpm rating for the motor you are using. if this information is not readily available, Consult

your motor manufaCturer.

This parameter, along with P 0.02 and P 0.03, determines the desired Maximum Output Frequency of the AC Drive. The Maximum Output Frequency can be calculated as follows:

•

Max� Out� Freq� = ( P0�04 Motor Max� RPM ÷ P0�03 Motor Base RPM ) x ( P0�02 Motor Base Freq� )

If an output limit based on Maximum Output Frequency is desired, use the following equation to determine the corresponding value for Motor Maximum RPM:

•

P0�04 Motor Max� RPM = ( Max� Out� Freq� ÷ P0�02 Motor Base Freq� ) x ( P0�03 Motor Base RPM )

P1.00 Stop Methods

Settings: 0 Ramp to Stop

1 Coast to stop

This parameter determines how the motor is stopped when the AC drive receives a valid stop command.

•

Ramp: The AC drive decelerates the motor to Minimum Output Frequency (P2�06) according to

the deceleration time set in P1�02 or P1�06�

•

Coast: The AC drive stops output instantly upon command, and the motor free runs until it comes

to a complete stop�

The drive application or system requirements will determine which stop method is needed.

P1.01 ♦ Acceleration Time 1

Range: 0�1 to 600�0 sec Default Setting: 10 sec

This parameter is used to determine the rate of acceleration for the AC drive to reach Maximum Motor RPM (P0.04). The rate is linear unless Accel S-Curve (P1.03) is “Enabled.”

P1.02 ♦ Deceleration Time 1

Range: 0�1 to 600�0 sec Default Setting: 30�0 sec

This parameter is used to determine the time required for the AC drive to decelerate from the Maximum Motor RPM (P0.04) down to 0Hz. The rate is linear unless Decel S-Curve (P1.04) is “Enabled.”

Bus over-voltage trips may be caused by motor regeneration during rapid deceleration. If this tripping occurs, increase the deceleration time.

analog inPut exaMPles

Use the equations below when calculating the values for the maximum output frequency, Analog Input Offset, Analog Input Gain, and the Mid-point frequency.

A) Max output frequency =

( P0.04 Motor Max RPM ÷ P0.03 Motor Base RPM ) x ( P0.02 Motor Base Frequency )

This maximum output frequency calculation is NOT a parameter setting, but is needed in order to calculate the Analog Gain. The default maximum output frequency for the GS1 drive is 60Hz. If parameters P0.02, P0.03, or P0.04 are changed, then the maximum output frequency will change accordingly.

B) P4.02 Analog Offset % = ( min frequency reference ÷ max frequency reference ) x 100 C) P4.03 Analog Gain % =

( ( max frequency reference - min frequency ref ) ÷ max output frequency ) x 100

D) Mid-point frequency =

( ( max frequency reference - min frequency ref ) ÷ 2 ) + min frequency reference

This mid-point frequency calculation is NOT a parameter setting, but it shows the frequency reference of the drive when the potentiometer or other analog device is at its mid-point.

exaMPle 6: reduced analog gain

This example shows how to limit the Maximum Frequency Reference by reducing the Analog Input Gain. When the Analog Input is at its maximum value (10V or 20mA), the set-point frequency will be 50Hz. However, this reduced maximum frequency applies only to an Analog Input Source of Frequency Command. The Maximum Output Frequency can still can still go to 60Hz if controlled from the Keypad, RS-485 interface, Jog Command, or Multi-Speed settings.

Protection ParaMeters

P6.00 Electronic Thermal Overload Relay

Settings: 00 – Constant Torque

01 – Variable Torque 02 – inactive

This parameter determines the drive’s motor overload protection characteristic. The Variable Torque setting (01) allows less motor current at lower speeds than does the Constant Torque setting (00).

P6.00 = 00: Constant Torque (Recommended for inverter/vector duty motors)

Use this setting when using the drives with motors designed specifically for AC drive outputs and for running at low speeds with high currents. Motor currents will be 100% throughout the speed range, and can be up to 150% for one minute.

P6.00 = 01: Variable Torque (Recommended for fan-cooled standard motors)

Use this setting when using the drives with motors which are NOT designed specifically for AC drive outputs. Motors with shaft mounted fans offer poor cooling at low speeds; therefore the output can be derated at lower output frequencies. This derated current is for protecting the motor at lower speeds.

The output current is derated as follows:

•

(%) = [ ƒ

output

Example: If the rated motor current is 5A, and the output frequency is 25Hz, the derating will be 70%, and the overload will be 5.25A (150%) for one minute.

•

(%) = [ (25Hz) (1�2 %/Hz) ] + 40% = 70%

P6.01 Auto Restart after Fault

Range: 0 to 10 Default Setting: 0

After fault occurs (allowable faults: over-current OC, over-voltage OV), the AC drive can be reset/restarted automatically up to 10 times. Setting this parameter to 0 will disable the reset/restart operation after any fault has occurred. When enabled, the AC drive will restart with speed search, which starts at the previous Frequency. To set the fault recovery time after a fault, please see (P6.13) base-block time for speed search.

P6.02 Momentary Power Loss

Settings: Default Setting: 0 0 – Stop operation after momentary power loss� 1 – Continue operation after momentary power loss, speed search from Speed Reference� 2 – Continue operation after momentary power loss, speed search from Minimum Speed�

This parameter will only work if the Source of Operation (P3.00) is set to something other than 0 (Operation determined by digital keypad).

P6.04 Auto Voltage Regulation

Settings: 0 – AVR enabled

1 – AVR disabled 2 – AVR disabled during Decel 3 – AVR disabled during Stop

AVR function automatically regulates the AC drive output voltage to the Maximum Output Voltage (P0.00). For instance, if P0.00 is set at 200VAC and the input voltage is at 200V to 264 VAC, then the Maximum Output Voltage will automatically be regulated to 200VAC.

Without AVR function, the Maximum Output Voltage may vary between 180V to 264 VAC, due to the input voltage varying between 180V to 264 VAC.

Selecting program value 2 enables the AVR function, but also disables the AVR function during deceleration. AVR improves regulation of the DC bus voltage. With lower DC bus voltage, regeneration and overvoltage faults are reduced, therefore allowing quicker deceleration.

P6.05 Over-Voltage Trip Prevention

Settings: 0 Enable Over-voltage Trip Prevention

1 Disable Over-voltage Trip Prevention

During deceleration, the AC drive DC bus voltage may exceed its Maximum Allowable Value due to motor regeneration. When this function is enabled, the AC drive will stop decelerating, and maintain a constant output frequency. The drive will resume deceleration when the voltage drops below the factory-preset value.

P6.10: Under certain conditions, the AC drive output current may increase abruptly, and exceed the value specified by P6.10. This is commonly caused by rapid acceleration or excessive load on the motor. When this function is enabled, the AC drive will stop accelerating and maintain a constant output frequency. The AC drive will only resume acceleration when the current drops below the maximum value.

P6.11: During steady-state operation with motor load rapidly increasing, the AC drive output current may exceed the limit specified in P6.11. When this occurs, the output frequency will decrease to maintain a constant motor speed. The drive will accelerate to the steady-state output frequency only when the output current drops below the level specified by P6.11.

When a momentary power loss is detected, the AC drive turns off for a specified time interval determined by P6.13 before resuming operation. This time interval is called Base-Block. This parameter should be set to a value where the residual output voltage due to regeneration is nearly zero, before the drive resumes operation.

Following a power failure, the AC drive will start its speed search operation only if the output current is greater than the value determined by P6.14. When the output current is less than that of P6.14, the AC drive output frequency is at a “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 failure.

The block transfer parameters (P9.11~P9.20) are used to read and write to and from non-consecutive drive addresses via Modbus.

For writing to any of the parameters from P0.00 to P8.01, a group of 10 block transfer parameters (P9.11 to P9.20) is available in the GS1 AC drive. This sequential block of parameters can be used to “group” various miscellaneous non-sequential parameters, so that you can update the parameters in one programming write block instead of having to use multiple write commands.

For example, it would typically take three different write commands to change the three non-sequential parameters Accel Time 1 (P1.01), Accel S-curve (P1.03), and Multi-speed 1 (P5.01).

However, you could make the same three changes using one write command by setting P9.11 to P1.01, P9.12 to P1.03, and P9.13 to P5.01, so that the parameters become sequential.

GS1 Serial Comm Port

For example, it would typically take three different write commands to change the three non-sequential parameters Accel Time 1 (P1.01), Accel S-curve (P1.03), and Multi-speed 1 (P5.01).

However, you could make the same three changes using one write command by setting P9.11 to P1.01, P9.12 to P1.03, and P9.13 to P5.01, so that the parameters become sequential.

commuNIcATING WITh AuTomATIoNdIRecT plcs

The following steps explain how to connect and communicate with GS1 AC drives using AutomationDirect PLCs.

GS1 drives have a provision for shutting down control or power to the inverter in the event of a communications time out. This feature can be set up through parameters P9.03, P9.04, and P9.05.

steP 1: choose the aPProPriate cPu

The GS1 AC drives will communicate with the following AutomationDirect PLCs using Modbus communications.

•

Modbus control is easier to accomplish from a DirectLOGIC PLC with an RS-485 port and MRX/ MWX, or from a CLICK PLC using Send/Receive instructions.

120 Termination Resistor

For Single Cable Runs of 2m (6.6 ft) or less to only one AC Drive: Use pre-terminated cable GS-485HD15-CBL-2 for easy wiring.

rs-485 connections for MultiPle drives

ZIPLink™ RS-485 communication boards (ZL-CDM-RJ12X4 or ZL-CDM-RJ12X10) provide an easy means to break out the RS-485 signal to several drives at one location, which creates a star configuration. However, the transmission errors are negligible, so this configuration is acceptable for proper operation of the VFDs.

rs-485 direct connections

Termination Resistors are required on both ends of RS-485 networks; especially on long runs. Select resistors that match the impedance rating of the cable (between 100 and 500W).

Recommended RS-485 cable: Belden 9842 or equivalent.

rs-232c to rs-485 conversion

An RS-485 network cable can span up to 1000 meters (4000 feet). However, most DirectLOGIC PLCs have only RS-232C communication ports, and require an FA-ISOCON (RS-232C to RS-422/485 network adapter) in order to make an RS-485 connection.

If an FA-ISOCON module is used, set the module DIP switches as required. Refer to the FA-ISOCON manual for more detailed information.

FA-ISOCON Switch Settings:

S21~S23 OFF, ON, ON (19200 baud) S24~S27 OFF (Automatic Network Transmit Enable) Terminate ON (end of run term resistors) Bias (2) ON (end of run bias resistors) 1/2 DPX (2) ON (RS-485 TXD/RXD jumpers)

ethernet connection using gs-edrv(100)

The GS-EDRV(100) provides an Ethernet link between a control system and a GS1 AC drive. It mounts on DIN rail and connects a drive to an Ethernet hub/switch or PC. The GS-EDRV(100) processes signals to and from the drive. It formats the signals to conform with the Ethernet standard to the H2-ERM(100) or H4-ERM(100), KEPdirect EBC I/O server, or independent controller with a MODBUS TCP/IP driver. This Ethernet interface allows for great connectivity to many control system architectures. An additional feature is the built-in web browser which allows users to configure and control the drive from any web browser via the IP address of the GS-EDRV(100) card.

clIck modbus lAddeR pRoGRAmmING

The set up for all of the CLICK CPUs is very similar. However, there may be some subtle differences between CPUs, or for the requirements of your particular program. Refer to the CLICK programming software internal help file for more information regarding CLICK programming.

The following ladder program shows some examples of how to control the GS1 AC drive through Modbus RTU. The drive should be set up and tested for communications before it is connected to a load.

Warning: a drive should never be ConneCted to a load until any appliCable CommuniCation programs

have been proven.

Warning: Write programs in suCh a Way that the program does not erroneously overWrite a remote stop

Command With a run Command, suCh as When p3.00 is set to 03. this example program prevents suCh an aCCidental overWrite.

These programs are for illustrational purposes only, and are not intended for a true application.

seParate run coMMand write instruction

Why do we write the Run Command with a separate write instruction? If we write the Run Command to the drive along with the Speed Reference, Direction, External Fault, and Fault Reset Commands, we can keep the parameter addresses in sequence, and we can update all five of the commands with one write instruction. This method is valid only if we disable the drive’s keypad STOP button (P3.00 = 04).

Typically, the keypad STOP button will be enabled (P3.00 = 03), and we need to prevent a change in one of the other commands from overriding a keypad Stop Command by causing a previous Run Command to be rewritten to the drive. By using a separate Run Command write instruction, only a deliberate Run Command change by the program will run the drive again after a stop.
