GSDA-AI-V5

Optional analog voltage or current input card for open-frame GSD5-240-10C series DC drives only

This option card allows for the use of either a grounded or non-grounded remote DC signal such as

0–5 VDC through 0–250 VDC, 4–20mA, or a remote speed potentiometer. The DC input signal type can

be selected for voltage (V

(P4) selection that should be set to the (Lo) setting when using a 4–20mA signal or voltage ranges of

0–5 VDC through 0–25 VDC. When using voltage ranges of 0–25 VDC through 0–250 VDC, this jumper

must be set to (Hi). The GAIN trim pot is used to set full linear output in reference to the input signal

range. The output of this remote signal isolation board is a linear signal that is proportional to the

remote input signal being supplied.

GSDA-AI-V5 Setup Procedure

1) With motor connected and NO power at the drive, connect a DC voltmeter (meter must not be

grounded) to control outputs as follows: Meter COMMON to the -ARM terminal; Meter POSITIVE

to the +ARM terminal Select correct meter range (0-90V or 0-180V)

2) Preset GAIN trim pot (analog voltage follower board) fully CCW, place range jumper clip in proper

position

3) Preset control as follows: MIN and IR COMP fully CCW; MAX at 50%

4) Apply desired AC voltage to drive and analog voltage follower board

5) With 0 volts into analog voltage follower board, adjust MIN trim pot on drive to eliminate

deadband To do this, increase MIN fully CW, and then adjust CCW until meter reads 0V

6) Apply maximum input voltage to analog voltage follower board input

7) Adjust GAIN until no further change in voltage output occurs, then turn CCW until a 5V drop

occurs, and then set control MAX to 90VDC (for 120V input) or 180VDC (for 240V input)

8) For Closed Loop systems the IR COMP should remain fully CCW For Open Loop systems, set IR

per set-up procedure

9) Some interaction between trimpots may occur Recheck the MIN trim pot setting and repeat steps 5

through 7 as needed
