The functionality for both with or without reverse current
brake functionality is as follows:
These examples are only valid with Edge control (default
setting).
If DigIn 1 “RunFWD” is closed and DigIn 3 “RunREV” is
open, the mains contactor (K1) for running in forward
direction will be activated by relay R1, and the motor will
start in forward direction. DigIn 1 “RunFWD” can be
opened during forward running without any effect. If DigIn
2 “Stop” is opened, the stop according to settings in menu
group [340] will be performed. When the stop is finished,
the mains contactor for running forward (K1) will be
deactivated by relay R1.
Exception is if Reverse current braking is selected in menu
“[344] Brake Method”. In this case contactor K1 will be
deactivated when stop command is activated and contactor
K2 is activated instead until stop is finished.
If DigIn 3 “RunREV” is closed while DigIn 1 “RunFWD” is
open, the mains contactor for running in reverse direction
(K2) will be activated by relay R2 and the motor will start in
reverse direction. DigIn 3 “RunREV” can be opened during
reverse running without any effect. If DigIn 2 “Stop” is
opened, a stop according to the stop settings in menu group
[340] will be performed. When the stop is finished, the
mains contactor for reverse running (K2) will be deactivated
by relay R2.
Exception is if Reverse current braking is selected in menu
“[344] Brake Method”. In this case contactor K2 will be
deactivated when stop command is activated and contactor
K1 is activated instead until stop is finished.
If both DigIn 1 “RunFWD” and DigIn 3 “RunREV” are
closed at the same time, a stop is performed according to the
stop settings in menu group [340]. In this case no start will
be allowed.
