With Potentiometer n
command value from potentiometer:
with 1V comm. value
with10V comm. value
command value from CNC\PLC:
with 0.8V comm. value adjust to 10% of maximum speed
Changing direction of rotation
change motor- and tacho-connection
with armature voltage regulation change only motor-connection.
