Description
Sets a custom motor current fault limit.
The drive automatically sets an internal motor current
limit according to the drive hardware. The internal limit
is appropriate in most cases, but this parameter can
be used to set a lower current limit, for example, to
protect a permanent magnet motor from
demagnetization.
Note: The limit defines the maximum peak current of
one phase.
With this parameter at 0.0 A, only the internal limit is
in force.
Custom motor current fault limit. For scaling, see
parameter 46.5.
Selects the stop mode when a non-critical fault occurs.
The drive coasts to a stop.
The drive follows the ramp specified for an emergency
stop in parameter 23.23 Emergency stop
Selects how the drive reacts when the communication
to an I/O extension module fails.
No action taken.
The drive generates a warning,
The drive trips on a fault,
Shows the status bits for sync loss supervision activity.
1 = Sync loss condition is detected.
1 = Sync loss condition is detected and
sync warning is triggered.
1 = Sync loss condition is detected and
fault is triggered.
1 = Supervision function is enabled and condition of
cos phi signal is monitored.
1 = Drive output value is above the value defined in
parameter 31.202 Sync loss minimum detection
1 = Actual cos phi value is below the value defined in
parameter 31.206 Sync loss cos phi minimum
1 = Cos phi value has dropped more than or is equal to
the limit defined by parameter 31.205.
