● 0: Deceleration to stop
The frequency converter decelerates to stop according to the defined deceleration
time.
– If a fault happens due to too fast deceleration, extend the deceleration
time or calculate if additional brake choppers / resistors are required.
– If the frequency is lower than the "Stopping DC braking initial frequen‐
cy" [b1.41] and "DC braking time" [b1.42]≠0, DC braking is activated.
The DC braking current is decided by [b1.43].
– DC braking is suitable for circumstances where regular deceleration to
stop or quick stopping is required. The larger DC braking current, the
larger braking force. However, the withstanding capability of the motor
has to be taken into account.
● 1: Freewheeling to stop
Once the stopping command is activated, the frequency converter stops output and
the motor mechanically freewheels to stop.
● 2: Freewheeling in STOP-command, decelerating when direction changes
This function also allows the frequency converter freewheeling to stop if STOP-com‐
mand is active and decelerating to stop according to stopping mode (deceleration
time and stopping DC braking if necessary) when direction change command is ac‐
tive during running.
The digital input "freewheeling to stop" is an additional source for the
STOP command. When the digital input is active, the frequency converter
will be disabled immediately and freewheel to stop, no matter its previous
state. The frequency converter will only return to the running state when a
run command is active and then the digital input goes inactive. Please re‐
fer to [E0.01] ~ [E0.05] for more details.
