6.3.3 Motor Potentiometer
Description
The digital motor potentiometer enables you to set speeds remotely using
switching signals (+/- keys). This is activated via terminals X520:2 and X520:3.
Provided that a logical 1 is present at terminal -X520:2 (increase setpoint), the
internal counter adopts this setpoint. You can set the integration time (time taken
for the setpoint to increase) via the operator panel using parameter p1047. The
setpoint can be decreased in the same way via terminal -X520:3 (decrease
setpoint). You can set the deceleration ramp via the operator panel using
parameter p1048.
Prerequisite
p1070 = r1050
Main setpoint is specified by motor potentiometer
