E51 Error
of
frequency inverter / motor regulation
Signal error between MCU5 and
frequency inverter.
Only applicable at digital control (RS485)
of MCU5/frequency inverter

shows the hexadecimal number of the original error
code of the frequency inverter (for example “b1” of error message
“E.PUE” =
PU disconnection
).
N
Check RS485 plug at the MCU5 control board
N
Check RS485 plug at the frequency inverter
N
Check RS485 plug at the optocoupler board
N
Maybe defective frequency inverter
N
Maybe power supply too weak because of an extension cable
etc.
N
Check power supply and power cord
