Notes:
• Jogging is not operational when the drive start command is on, or when the drive
is in local control.
• Normal start is inhibited when jog enable is active.
• The ramp shape time is set to zero during jogging.

Speed controller tuning

The speed controller of the drive can be automatically adjusted using the autotune
function (parameter
inertia of the motor and the machine. It is, however, also possible to manually adjust
the controller gain, integration time and derivation time. Autotuning can also be
performed from an external control location.
Autotuning can be performed in four different ways depending on the setting of

fails, the SPEED CTRL TUNE FAIL alarm will occur for approximately 15 seconds. If
a stop command is given to the drive during the autotuning routine, the routine will
be aborted.
Description
1 Normal operation overrides the jogging. Drive accelerates to the speed reference along
the active acceleration ramp.
1 Start command overrides the jog enable signal.
0 Drive decelerates to the jogging speed along the deceleration ramp of the jogging function.
0 Drive runs at the jogging speed.
0 Drive decelerates to zero speed along the deceleration ramp of the jogging function.
