IronHorse GSD4A Series DC Drives General Information IronHorse GSD4A DC drives are designed to control DC Permanent Magnet, Shunt Wound, and some Universal (AC/DC) motors. Incoming AC voltage is converted to adjustable full-wave rectified DC voltage to operate the DC motor. Also, a full-wave field voltage is provided for shunt wound motors.
INHIBIT TERMINAL PINS – Allows the user to (hard) quickly stop and start the control output via a SPST switch. Using the inhibit inputs will bypass Accel and Decel ramps. ACCEL & DECEL – Has adjustable accel and decel with a setting range of 0.5-8 seconds for accel and 0.5-6 seconds for decel.

GSD4 Control Features MINIMUM SPEED – Allows adjustment of the motor speed when the speed pot is set at minimum (CCW). This permits the user to eliminate “Deadband” on the main speed control, permitting zero calibration. Clockwise rotation of “MIN” trim pot increases speed. MAX SPEED (Maximum Speed) –...

Operational Description: 0 to 10 VDC Analog Reference Signal to GSD4 IronHorse GSD4 drives, though advertised to work with a 0 to 10 volt reference, exhibit an offset in output response when used in this manner. With 0 to 10 VDC connected to the GSD4 drive, output voltage is zero volts until the analog reference value reaches two volts, where the GSD4 drive output voltage will begin to rise.
Start-Up Start-Up for GSD4A-240-xC 1) Recheck all wiring. Accidental grounds, loose or pinched wires on armature or speed pot wires may damage the DC drive when power is applied. 2) Check to see that the incoming power is of the correct voltage. 3) Check to make sure the input line voltage jumper selection (JP2) is set to the correct incoming service.
Page 23
Start-Up for GSD4-240-10N4X 1) Safety Precautions: a) Observe the normal safety precautions for the voltages involved. We strongly suggest that only qualified electricians or service people should install, troubleshoot, maintain, or service the drive, motor, and interconnect wiring. b) Be sure power is disconnected or shut OFF at fuse box or circuit breaker when installing the drive and making adjustments (except running adjustments).
Trim Pot Adjustments NOTE: A DC motor must be connected to the drive in order to make accurate trim pot adjustments. If the system is unstable after the previous Start-Up procedure, then adjust the trim pots as described in this section. GSD4A-240-xC Trim Pot Adjustment GSD4A-240-xC Trim Pot Adjustment Trim Pot...

GSD4-24A-5C Trim Pot Adjustment GSD4-24A-5C Trim Pot Adjustment * Trim Pot Function Adjustment Sets minimum motor speed 1) Set Speed pot to zero (fully CCW). when speed pot is set at zero. 2) Rotate MIN trim pot CW until motor starts to rotate. CW rotation will increase 3) Slowly rotate MIN trim pot CCW until motor stops.

GSD4-240-10N4X Trim Pot Adjustment Use the applicable sections of the following procedures if the “Start-Up” procedures did not provide satisfactory motor/control performance. Follow the Safety Precautions given in the “Start-Up” section. MAX Setting If a different maximum speed or voltage is desired, adjust the MAX trim pot (on circuit board) as follows: 1) Turn ON AC power to the control.
