List of errors and system errors
When an error occurs, the inverter switches off; for the corresponding error num-
bers, refer to the flash code table or the PC tool.
Error messages can only be acknowledged when the error is no longer pre-
sent.
! Error messages can be acknowledged as follows:
1. Digital input (programmable)
2. via the hand-held unit MMI
3. Automatic acknowledgement (parameter 1,181)
4. Switching the device on and off
5. via fieldbus (CANOpen, Profibus DP, EtherCAD)
Below is a list of possible error messages. For errors not listed here, please con-
tact the manufacturer.
Error detection
No. Error name Error description Possible cause / remedy
1 Low voltage 24 V application Supply voltage of the applica-
tion is less than 15 V Overload of the 24 V supply
2 Over-voltage 24 V application Supply voltage of the applica-
tion is greater than 31 V Internal 24 V supply is not OK or
external power supply is not OK
3 Version error of client PLC The version of the client PLC
does not match the device
firmware Check the version numbers of
the customer PLC and device
firmware
4 Communication applica-
tion<>performance
The internal communication
between the application and
power printed circuit board is
out of order EMC interference
5 Parameters distributor The internal distribution of the
parameters during the initialisa-
tion has failed Parameter set is incomplete
6 Timeout performance The power unit does not re-
spond
Operation with 24 V without
power supply
7 Cable breakage analogue input
1 (4 - 20 mA / 2 - 10 V) Current or voltage is less than
the lower limit of the analogue
input 1 (this error monitoring is
activated by setting the parame-
ter 4,021 to 20%) Cable breakage, defective ex-
ternal sensor
8 Cable breakage analogue input
2 (4 - 20 mA / 2 - 10 V) Current or voltage is less than
the lower limit of the analogue
input 2 (this error monitoring is
activated by setting the parame-
ter 4,021 to 20%) Cable breakage, defective ex-
ternal sensor
9 Blocking detection The drive shaft of the motor is
blocked. 5.080 Remove blockage
10 Overtemperature of drive con-
troller application Internal temperature too high Insufficient cooling, low speed
and high torque, clock fre-
quency too high
11 Bus timeout No response from the bus de-
vice or HAND-HELD UNIT MMI /
PC Check bus wiring
12 Confirmation error The number of max. automatic
acknowledgements (1,182) has
been exceeded Check the error history and
