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 (
) 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
for 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
DURA
pulse
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.
