10.1.3 Programming of Speed Control

The required motor speed is set via a potentiometer
connected to terminal 53. The speed range is 0 to 1500
RPM corresponding to 0 to 10 V over the potentiometer.
Starting and stopping is controlled by a switch connected
to terminal 18. The Speed PID monitors the actual RPM of
the motor by using a 24 V (HTL) incremental encoder as
feedback. The feedback sensor is an encoder (1024 pulses
per revolution) connected to terminals 32 and 33.
