10.4 Fault codes

A fault code is displayed in the format of ErXX-X, in which XX indicates the main code and X indicates
the sub code.
For example, in
Fault code
Er01-0 IGBT fault
Brake pipe fault (for models of 7.5kW or
Er01-1
above)
Er01-2 Phase-U IGBT fault
Er01-3 Phase-V IGBT fault
Er01-4 Phase-W IGBT fault
Er01-5 IPM fault
Er02-0 Encoder fault–Encoder offline
Encoder fault–Encoder feedback
Er02-1
deviation too large
Er02-2 Encoder fault– Parity error
Er02-3 Encoder fault–CRC error
Er02-4 Encoder fault–Frame error
Er02-5 Encoder fault–Short frame error
Er02-6 Encoder fault–Encoder timeout
Er02-7 Encoder fault–Second-encoder timeout
Encoder fault–Encoder battery
Er02-8
low-voltage alarm
Encoder fault–Encoder battery
Er02-9
undervoltage
Er02-a Encoder fault–Encoder overheating
Encoder fault–Encoder EEPROM
Er02-b
