Description
Specifies the maximum wear imbalance, or difference in
running times between any motor, used by the
setting of parameter 76.70 PFC
Time.
Upper speed limit for the Autochange to occur. The
Autochange occurs when:
• the condition defined in
and,
• the speed of the drive motor
the speed limit defined in this parameter.
Note: When the value is selected as 0%, this speed limit
check is disabled.
Speed/frequency in percentage of the nominal speed or
frequency of the drive motor.
Selects whether only auxiliary motors or all motors are
included in the Autochange function.
All motors, including the one connected to the drive
participates in the autochange. The Autochange logic will
connect the drive to each of the motors according to setting of
parameter 76.70 PFC autochangee.
Note: The first motor (PFC1) also requires the appropriate
hardware contactor connections and PFC1 must be defined
in one of the relay output source parameters.
Only auxiliary (direct-on-line) motors are affected by the
autochange function.
Note: PFC1 refers to the motor that is fixed to the drive and
must not be selected in any of the relay output source
parameters. Only the starting order of the auxiliary motors will
be rotated.
Defines if the PFC motor 1 can be started. An interlocked
PFC motor cannot be started.
0 = Interlocked (not available), 1 = Available.
PFC motor is interlocked and not available.
PFC motor is available.
