6 Operating status messages
The majority of functions and operating data of the frequency inverter are continuously monitored and
simultaneously compared with limit values. If a deviation is detected, the frequency inverter responds
with a warning or an error message.
For basic information about this, please refer to the frequency inverter operating instructions.
All errors or reasons which result in a switch-on block of the frequency inverter and which are
associated with STO functionality are listed below.

Overcurrent module
Module error (short-term)
• Short circuit or earth fault at the FI output
(motor cable or motor)
• Optional braking resistor, defect/check
• Optional motor choke, defect/check
Further notes
• More causes of error:
– Wrong size of breaking resistor
– Motor cable too long
– Cable resistance too high or voltage at Safe Pulse
Block too low
• Do not disconnect P537!
• The error may significantly reduce the service life of
the device or even destroy it.

Parameter loss
(maximum EEPROM value
exceeded)
Error in EEPROM data
• Software version of the stored data set not compatible
with the software version of the FI.
NOTE: Faulty parameters are automatically reloaded
(factory setting).
• EMC interferences (see also E020)
8.1
Inverter type incorrect
• EEPROM faulty
8.2
External copy error
(ControlBox)
• Check ControlBox for correct position
• ControlBox EEPROM defective (P550 = 1)
8.4
Internal EEPROM error
(Database version incorrect)
The configuration of the frequency inverter was not correctly
identified.
• Switch mains voltage off and on again.
