WARNING
When changing from remote control to local
control, the softstarter stays in present state. That
means, if the the softstarter is running the motor
when switching between the remote control and
local control, the softstarter will continue to run
the motor.
WARNING
Since the keypad has highest priority, when in
local control, neither the digital inputs nor the
fieldbus communication can stop the motor if it
is running. When in local control the only stop
command that can stop the motor is the stop key
on the keypad.
