Macro 5 PID (set-point control)
2005
The PID control macro enables the drive's own internal PID controller to control the speed of the motor. Analog input 1 is configured for the main
speed reference, analog input 2 is the PID reference and analog input 3 is the PID feedback. A digital input selects between an analog speed
reference and the PID control.
Macro 6 Axis-limit control
2006
The Axis limit control macro configures the drive for use with limit switches so that the drive is stopped when a position limit has been reached. The
speed reference can be either unipolar or bipolar.

during deceleration. This distance will
be increased if the deceleration time
is extended
