GS20 AC Drives Installation Instructions
Sensorless Vector Control Variable Frequency Micro-drive
• Please read this instruction sheet thoroughly before installation and retain for later
reference.
• To ensure the safety of operators and equipment, only qualified personnel familiar
with AC drives should install, wire, program, and operate the GS20 drive. Always read this instruction sheet
thoroughly before using the GS20 drive, especially the WARNING, DANGER and CAUTION notes. If you have any
questions, please contact AutomationDirect.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY
DANGER
• The ground terminal of the GS20 drive must be grounded correctly. The grounding method
must comply with the laws of the country where the GS20 drive is to be installed.
• After power has been turned off, the capacitors in the GS20 drive may retain a charge for
several minutes. To prevent personal injury, visually verify that the “CHARGE” LED has
turned off. Then measure to confirm that the DC bus voltage level between terminals (+1)
and (-) is less than 25VDC before touching any terminals. (Capacitor discharge will take at
least 5 minutes for most GS20 models)
• The CMOS ICs on the internal circuit boards of the GS20 drive are sensitive to static
electricity. Please DO NOT touch the circuit boards with your bare hands before taking
anti-static measures. Never disassemble the internal components or circuits.
• If wiring changes must be made, turn off power to the GS20 drive before making those
changes. Allow the internal DC bus capacitors in the GS20 drive sufficient time to discharge
prior to making changes in power or control wiring. Failure to do so may result in short
circuit and fire. To ensure personal safety, allow DC bus voltage to discharge to a safe level
before making wiring changes to the GS20 drive.
• DO NOT install the GS20 drive in locations subject to high temperature, direct sunlight, or
flammable materials.
WARNING
• Never apply power to the output terminals U/T1, V/T2, W/T3 of the GS20 drive. If a fault
occurs during operation of the GS20 drive, refer to the fault code descriptions and corrective
actions to reset the fault before attempting to operate the GS20 drive.
• DO NOT use Hi-pot test for internal components. The semi-conductors in the GS20 drive are
easily damaged by high voltage.
CAUTION
• Long motor lead lengths may result in reflective wave due to impedance mismatch between
the motor cable and the motor. Reflective wave may damage the insulation of the motor.
To avoid the possibility of reflective wave damage, use an inverter-rated motor with an
insulation rating of 1600 volts. A load reactor installed between the GS20 drive and motor
will help to mitigate reflective wave.
• Nominal supply voltage to the GS20 drive should be less than or equal to 120/240/480 volts
AC depending on GS20 model.
• Nominal supply current capacity should be less than or equal to 100kA for all GS20 models.
• The GS20 drive must be installed in a clean, well-ventilated and dry location, free from
corrosive gases or liquids.
• The GS20 drive must be stored within an ambient temperature range from –40°C to +85°C,
and relative humidity range of 0% to 90% without condensation.
• Do not apply AC power to the GS20 drive with the front cover removed. Following a fault of
the GS20 drive, wait 5 seconds before pressing the RESET key.
• To improve power factor, install a line reactor ahead of the GS20 drive. Do not install power
correction capacitors in the main AC supply circuit to the GS20 drive to prevent drive faults
due to over-current.
Minimum Wiring
• AC input power to R/L1, S/L2, T/L3 (for single-phase input, use two of the terminals) (For applicability of 1-phase
input power, please refer to Chapter 1 of the DURApulse GS20 AC Drives User Manual at AutomationDirect.com.)
• Ground from the power supply
• Drive power to the motor (U, V, W on T1, T2, T3) (For use with 3-phase motors only!)
• Ground to the motor
• STO1 and STO2 (both must be wired through appropriate N.C. safety-rated contacts to DCM or the
factory-installed jumpers must be left in place)
With this minimal wiring, the drive can be operated via the keypad to test the motor and drive installation.
See the “Parameter Set Up” (page 4) section to configure the drive for keypad operation.
Recommended Safety Wiring
We strongly recommend that customers use the STO safety feature.
The Safe Torque Off (STO) function turns off the power supplied to the motor through the hardware, so
that the motor cannot produce torque. This method of removing power from the motor is considered an
emergency stop, also known as “coast to stop.”
To use this feature, disconnect the appropriate factory-installed jumpers and wire a safety relay or safety PLC
as shown. The E-Stop pushbutton should be wired through a Safety Relay or PLC to meet Category 3 safety
requirements. See User Manual Appendix E for wiring the GS20 with STO.
Wiring Diagrams
RFI Jumper Removal
If the power distribution system supplying the GS20 AC drive is a floating (IT) or an
asymmetric ground system (including most 120V inputs), the RFI jumper must be
removed.
Removing the RFI jumper uncouples the internal RFI capacitor (filter capacitor)
between the GS20 drive frame and circuitry to avoid damaging those circuits and
(according to IEC 61800-3) to reduce ground leakage current.

Wiring Precautions
1) The factory default condition is +24 V/ S1/ S2 shorted by jumper, as shown in the block 1 of the figure above.
Refer to the wiring chapter of the User Manual for more details.
2) The +24 V power supply for safety function is only for STO use and cannot be used for other purposes.
3) The RELAY terminal uses the PCB terminal block:
• Tighten the wiring with a 3.5 mm width and 0.6 mm thickness slotted screwdriver.
• The ideal length of stripped wire at the connection side is 6–7 mm.
• When wiring bare wires, make sure they are perfectly arranged to go through the wiring holes.
4) The control circuit terminal uses a spring clamp terminal block:
• Tighten the wiring with a 2.5 mm width and 0.4 mm thickness slotted screwdriver.
• The ideal length of stripped wire at the connection side is 9 mm.

DURApulse GS20 AC Drive Quick-Start Guide
GS20_QSP 1st Edition, Rev C 03/03/2022
Introduction – How To Get Started
Automationdirect.com would like to thank you for your purchase of the Durapulse GS20 AC drive. The GS20
drive is a state-of-the-art, full-featured AC drive. The Quick-Start Guide below will introduce you to many of
the GS20 drive features and help you configure the GS20 drive in a minimum amount of time.
STO (Safe Torque Off) / Emergency Stop
The GS20 drive offers Safe Torque Off (STO) functionality, instead of a standard Emergency Stop circuit. STO
provides the ability to immediately turn off the output of the GS20 drive in the event of an emergency, without
the need for an emergency stop contactor between the drive and motor.
Please see the Control-Circuit Wiring diagrams (page 1) for how to wire the STO circuit. From the factory,
the GS20 STO terminals are jumpered and the STO circuitry of the drive is bypassed. STO is recommended for
personnel safety.
After wiring the drive (but before applying power), the first thing you should do is press the E-stop button (or
otherwise break the safety circuit) and verify that the circuit between the STO1/STO2 terminals and the STO
+24V terminal is not connected. If these circuits are open, the STO feature will stop all power from going to the
motor and there will be no danger of unexpected movement when you power up the drive.
Powering Up the GS20 Drive
Apply AC line power to the GS20 drive, but don’t engage the safety circuit yet (keep the E-stop PB pushed in).
Starting, Stopping, and Controlling the Speed of the GS20 Drive
Out of the box GS20 drives are set to use the keypad buttons to RUN and STOP the drive and vary the drive
speed. The drive can also be configured to run from potentiometers, external pushbuttons, Ethernet
communication, etc.
Do not attempt to run the motor yet. Certain parameters (especially the motor protection parameters) must
be set first.
Configure the Drive
The tables below list those parameters typically used in most applications. You can navigate to any of these
parameters through the keypad. (Refer to page 3for information and instructions for using the Digital
Keypad.)
All applications need to configure the parameters in the “Quick Configuration” table. At minimum, you MUST
configure these motor parameters before operating the drive:
• 01.02 Motor1 Max Output Voltage (this will typically be either 230V or 460V)
• 05.01 Motor1 Rated Amps (depends on the motor)
• 01.01 Motor1 Max Output Frequency (this will typically be 50Hz or 60Hz)
The main configuration parameters required to get your drive up and running are included in this guide.
For more advanced configuration options, please see the User Manual. Your application will dictate which
parameters need to be configured. It is NOT necessary to configure every parameter listed in the tables in the
User Manual, use only those you need.

After configuring the minimum settings, you can now engage the safety circuit. The RUN and STOP/RESET
buttons should Start and Stop the drive. To adjust the output frequency, press the MENU button repeatedly
until the “F xx” appears for “Frequency Setpoint”. Use the Up and Down arrow buttons to adjust the frequency,
then press ENTER to confirm. Press ENTER again to return to the main menu.
Parameter Set Up
DURApulse GS20 AC Drives offer parameter setup from the keypad for some of the most common drives
applications. Choose parameters from the table below, then set the applicable parameters for that
application as shown.
To Configure Parameters:
From the power up screen:
1) Press MENU until you see H 0.00 (this is the actual drive frequency) and press ENTER.
2) Use the UP/DWN arrows to select the parameter group you want and press ENTER.
3) Use the UP/DWN arrows to select the parameter number you want within that group and press ENTER.
4) Change the value of the parameter using the UP/DWN arrows and press ENTER.
5) Press MENU to exit back to the main menu.
6) Repeat as needed until all required parameters are configured.
Please refer to the user manual if you need more detailed information about the
parameters.

OPTIONAL CONFIGURATION SETTING:
GS2 mode is an optional setting for users who want the drive to operate in the legacy GS2 parameter
configuration. This mode changes the entire parameter structure of the drive. See the GS20 User Manual
Appendix G for more details.
Entering and Exiting “GS2” Mode
GS20 drives that have an equivalent GS2 model (same power and HP rating) have the option of being operated
in “GS2 Mode”. This allows you to use the new drive in exactly the same role as an older GS2 drive that needs
to be replaced, or in conjuction with existing GS2 drives.
Note that all drives will come factory standard with GS20 mode as the default setting.
Enter GS2 Mode
Note: To enter GS2 mode, parameters cannot be locked or set to read only, and the PLC must be disabled. If
any of these requirements are not met, you will be unable to set 00.02 to 20.
1) Set parameter 00.02=2, to reset to GS2 mode (step 1 of 2) and press ENTER.
2) Set parameter 00.02=20 to reset to GS2 mode (step 2 of 2) and press ENTER.
3) Reboot the drive by cycling power.
4) Configure GS2 parameters using the GS2 series User Manual.
Exit GS2 Mode
1) Set parameter 09.08=20 to reset to GS20 mode (parameters will reset). Press ENTER.
2) Reboot the drive by cycling power.
3) Configure GS20 parameters per the tables above and in the GS20 User Manual.

• External Flow Rate is across the heat sink.
• Internal Flow Rate is through the chassis.
• Published flow rates are the result of active
cooling using fans, factory installed in the
drive.
• Unpublished flow rates ( - ) are the result
of passive cooling in drives without factory
installed fans.
• The required airflow shown in the chart
is for installing a single GS20 drive in a
confined space.
• When installing multiple GS20 drives,
the required air volume would be the
required air volume for a single GS20 drive
multiplied by the number of GS20 drives.
• When calculating power dissipation (Watt
Loss), use the Total value. Heat dissipation
shown in the chart is for installing a single
GS20 drive in a confined space.
• When installing multiple drives, the volume
of heat/power dissipation should be the
heat/power dissipated by a single GS20 drive
multiplied by the number of GS20 drives.
• Heat dissipation for each model is calculated
by rated voltage, current and default carrier
frequency.

Minimum Mounting Clearances
When installing your GS20 drive, please keep the following in mind:
• Prevent fiber particles, scraps of paper, shredded wood, saw dust, metal particles, etc., from adhering to the
heat sink.
• Install the AC motor drive in a metal cabinet. When installing one drive below another one, use a metal
separation between the AC motor drives to prevent mutual heating and to prevent the risk of accidental fire.
• Install the AC motor drive in Pollution Degree 2 environments only: normally only nonconductive pollution
occurs and temporary conductivity caused by condensation is expected.
