Digital Potentiometer GSDA-DP * For accessories details, refer to the "GSD Series DC Drives Accessories" section at automationdirect.com. ** Input power supply must not exceed recommended voltage, or it may damage the GSD1 drive. Linear power supply can be sized per drive voltage and motor full load current.

10 vDC a GSD1 peraTional eSCripTion naloG eferenCe iGnal To IronHorse GSD1 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 GSD1 drive, output voltage is zero volts until the analog reference value reaches two volts, where the GSD1 drive output voltage will begin to rise.
DjUSTMenTS Before the power is applied, set the voltage selection jumper to the correct voltage. An incorrect jumper setting will not damage the drive, but will affect the trim pot adjustments. The speed potentiometer and trim pots should be preset as follows: reset 1) Preset Speed pot fully CCW�...
