overload of the motor I²t
does the control loop oscillate?
P-amplification too high mechanics stiff?
requirements too high? is warning /8/ evaluated?
over temperature of the output stage (> 95°C)
adequate cooling of the regulator?
ambient temperature too high?
over voltage on DC bus
ballast module ok? adequate ballast module?
chassis shorting and short circuit due to hardware
motor cabling ok? digital-loops setup ok?
short circuit to chassis in the motor? braking resistor:
ohm- value too low? try to start fresh! send in for
repair
WARNING!
Overload of the regulator I²t or motor I²t or temp.-
output stage too high. If no reaction within approx.
3sec.it switches off with signals /3/, /4/ or /5/. Signal
/8/ clears when there is no more danger or it is
switched off
mechanics stiff? defective bearings; cold grease?
reduce requirements and creep to next possible STOP
over temperature motor(NTC/PTC)
check overload of the motor / cooling etc.
motor temperature too high
check overload of the motor / cooling etc.
ballast active
Brake energy is removed
warning I²t ballast too high
ballast resistance usage >90%
switch off ballast
ballast resistance overloaded

Only warning respect. status indicator
The error signals are shown as long as there is control voltage (Us), also when the power (DC-Bus)
is switched off for safety reasons.
