– Error message caused through wrong motor datas (Nominal speed – Motor datas)!
– Error message caused through wrong motor datas (Nominal current – Motor datas)!
– Old machines: Please switch off the possition regulator! Or change the settings!
– Gearless: Is the motorwire correctly installed (U – V – W)?
– Overcurrent because there is a shortcut in the motorwire?
– Is the encoder wire connected correctly? Perhaps you must change the channels A and B?
- Is the car easily running? Have the fixing shoes enough oil? Is the half-load OK?
Overcurrent U - Overcurrent because there are wrong motor datas or oscillations of the car

Dissipator Temperature: Temperature Dissipator too high –
- The inverter is overloaded or the controller casing is too hot. Is the power class of the inverter
according to the motor?
- Has the controller cabinet an air ventilation? Is above the inverter casing enough air room?
- Are the fans of the inverter OK?
- Is there any dirt on the pcb-board or in the heat sink?
– There is no brake resistor connected or the type is incorrect -> Please measure the Ohm-
value!
– Main supply voltage too high -> Please check it – you must have a voltage of 400V AC!
– There are voltage peaks on the main supply?
- Is the frequency inverter connected to the ground?
DC-Undervoltage:–The supply voltage is too low or the main contactor is switched off during the
travel:
- The DC voltage is too low –> Please control the supply voltage!
- The maincontactors are switched off during the travel -> A phase of the supply voltage is miss-
ing!
- The power class of the inverter is too low for the motor!
- At the start, the main contactors do not switch ON -> The power supply is too low?
- At the start, the main contactors do not switch ON -> The safety circuit is interrupted (Doorcon-
tacts)
- At the start, the main contactors do not switch ON -> The Fuse is switched OFF?
- During the travel, the main contactors switch OFF -> The power supply is too low?
- During the travel, the main contactors switch OFF -> The safety circuit is interrupted (Doorcon-
tacts)
During the travel, the main contactors switch OFF -> The fuse is switched OFF?
