Cause / Remedy
x The selected starting time is shorter than the run-up time of the motor.
Remedy: extend starting time or increase current limit.
x x Set current limit has been exceeded or undershot, e.g. by a clogged fan filter or by the
motor stalling.
Remedy: check motor for cause of current limit violation.
x x One phase is connected to earth (only possible in bypass operation).
Remedy: check connections and wiring.
x Connection to the PC broken (if PC-controlled) or no key has been pressed for a long
period of time (> activity monitoring time) (if motor is key-controlled).
The control will be handed over to the inputs if they requested the control priority.
Remedy: reconnect PC or increase activity monitoring time and press a key at regular
intervals.
