The control program compares the absolute value of
parameter 71.04 Deviation act value
defined by this parameter. If the absolute value is within the
deadband range for the time period defined by parameter
71.40 Deadband delay, PID's deadband mode is activated
and 71.06 PID status word
PID's output is frozen and
frozen is set.
If the absolute value is equal or greater than the deadband
range, PID's deadband mode is deactivated.
Range
Defines the deadband delay for the deadband function. See
parameter 71.39 Deadband

Displays the running/stopped status of the PFC motors.
PFC1, PFC2, PFC3 and PFC4 always correspond to the
1st...4th motor of the PFC system. If
auxiliary PFC auxiliary PFC is set to
represents the motor connected to the drive and PFC2 the
first auxiliary motor (the 2nd motor of the system). If
set to All motors, PFC1 is the first motor, PFC2 the 2nd. The
drive can be connected to any of these motors depending on
the Autochange functionality.
