Check the auxiliary code (format XXXX
YYYY). "YYYY" indicates the problem
(see actions for each code below).
Repeat autotune until successful.
Make sure the prerequisites of the
autotune run are fulfilled. See section
Before activating the autotune routine
(page 46).
Decrease torque step (parameter 25.38)
or increase speed step (25.39).
Increase torque step (parameter 25.38)
or decrease speed step (25.39).
Decrease torque step (parameter 25.38)
or speed step (25.39).
parameter group 31 Fault
Check that it is safe to continue
operation. Reset the source of the
emergency stop signal (such as an
emergency stop push button). Restart
drive.
If the emergency stop was unintentional,
check the source of the stop signal (for
example, 21.05 Emergency stop
or control word received from an external
control system).
Informative warning. After stopping on a
ramp stop (Off1 or Off3) command, the
master sends a short, 10-millisecond
coast stop (Off2) command to the
follower(s). The Off2 stop is stored in the
event log of the follower.
Check that it is safe to continue
operation. Reset the source of the
emergency stop signal (such as an
