1: Coast to stop; after stop command is valid, the
VFD stops output immediately, and the load coasts
to stop as per mechanical inertia.
P01.09
Starting
frequency of DC
brake after stop
Starting frequency of DC brake after stop; during
decelerating to stop, when this frequency is
reached, DC brake will be performed after stop.
Demagnetization time (waiting time of DC brake
after stop): Before the DC brake, the VFD will block
output, and after the demagnetization time elapses,
DC brake will start. This function is used to prevent
overcurrent fault caused by DC brake during high
speed.
DC brake current after stop: it means the DC brake
force applied, the larger the current, the stronger
the DC brake effect.
