F2h
I²t- overload of the drive
1)
1)
does the control loop oscillate?
P-amplification too high mechanics stiff?
requirements too high? is warning /8/ evaluated?
66H
I²t overload of the motor
1)
1)
does the control loop oscillate?
P-amplification too high mechanics stiff?
requirements too high? is warning /8/ evaluated?
B6h
over temperature of the output stage (> 90°C)
1)
1)
adequate cooling of the regulator?
ambient temperature too high?
B6h
„flashing“
Drive Simulation Mode active

3Eh
over voltage on DC bus
1)
1)
ballast module ok? adequate ballast module?
3Eh
starts the device display immediately after
switching on the 24V control supply with 6"( no
reset) the device doesn't boot!
Reason: Resets function defect, no Firmware on
drive

E0h
chassis shorting and short circuit due to hardware
off
off
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
FEH
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
on
1)
mechanics stiff? defective bearings; cold grease?
reduce requirements and creep to next possible
STOP
F6h
over temperature motor(NTC/PTC)
off
1)
check overload of the motor / cooling etc.
2Eh
motor temperature too high
on
1)
check overload of the motor / cooling etc.
80h
