9.4.25 Control mode [825]
Mode 4 "control" allows pure speed control of the drive without position
control. In "control" mode, the drive can be moved in jog mode with the
fixed velocity levels 10 % and 100 % via a ramp-function generator (in a
later software version the velocity levels will be adjustable with U511).
The jog velocity is multiplied by the velocity override.
Control mode is suitable for commissioning (e.g. for optimizing the
speed controller) and maintenance purposes, etc.
You will find detailed information on "Control mode" in the
chapter of the same name in the Function Description of manual
/1/.
The following graphic shows the sequence in control mode.
