Name Description
Control data cannot be received nor-
mally.
· Transmission between the inverter and
digital operator cannot be established 5
seconds after supplying power.
· MPU peripheral element check fault
(on-line)
· Transmission between the inverter and
digital operator is established once
after supplying power, but later trans-
mission fault continues for more than 2
seconds.
· MPU peripheral element check fault
(on-line).
Inverter PCB control board fault.
Dynamic braking transistor has failed
Dynamic brake resistor duty cycle value
exceeded (>3% ED)
