DC brake:
If this command is activated, the DC brake is
active.
Switch-over of parameters:
If this command is activated, the inverter switches
over to the 2nd set of parameters. Motor data,
minimum and maximum limits and the accelerati-
on and deceleration times are switched over.
The concerned parameters are named A2xx.
Switch-over of ramps:
Two sets of acceleration and deceleration ramps
are avaliable. The signal “2nd ramp” is used to
switch between these two ramp sets. The values of
acceleration and deceleration time must be set in
parameter group A.
Contact closed: 2nd set of ramps active
Impulse lock:
If this command is activated, the inverter is locked
immediately, allowing the motor to come to stand-
still freely. The function can be inverted
(parameters C011 to C015). By setting parameter
b088 to position 00, the inverter starts from 0 Hz
once the FRS signal is cancelled.
However, if parameter b88 is set to position 01,
the inverter starts with the acutal frequency fo the
motor (“interception of the motor“).
In both cases, the inverter starts after the waiting
time set with parameter b003. If the speed of the
motor is declined during this time beneath the
matching (restart) frequency set with parameter
b007, a restart happens at 0 Hz.
