Meaning of the error code related to the frequency inverter
(motor drive control) function/ status
Unknown or incompatible power board
Invalid industrialization zone
Current measurement circuit
Internal thermal sensor detected fault
Download invalid configuration
PI Feedback detected fault
Error of
RS485 cable motor control
Cable defect or bad contact at the
connection MCU/frequency inverter
Only applicable for digital control
(RS485) of MCU5/frequency inverter
= E 52 ! FU flashing
§ $ % HELP flashing
The MCU5 control boards always send a reset message every time
the device is switched on. After 10 consecutive time-out failures, the
MCU generates the E52 error-message. This is equivalent to a
missing connection (e.g. cable defect) from MCU5 to frequency-
inverter.
N Check RS485 plug at the MCU5 control board.
N Check RS485 plug at the frequency inverter.
N Check RS485 plug at the opto coupler board.
N Contact authorized service engineer.
