PC_t1
Power-on buffer
half-voltage timeout
Unit disabled
Buffer resistor damage
Buffer contactor fault
Ensure the rectifier enabling bit is
set correctly
Ensure the buffer resistor without
damage is used
Ensure the buffer contactor without
fault is used.
OH1
IGBT overheat fault
Instantaneous overcurrent of the
rectifier
Three-phase output have interphase
or the grounding is short circuited
Air duct is blocked or fan is damaged
Ambient temperature is too high
Control board cables or plugs are
loose
Auxiliary power supply is damaged,
and undervoltage occurred for drive
voltage
The short through of bridge arm of
power modules occurred
Control board is abnormal
See solutions for overcurrent
Re-wiring
Dredge the vent duct or replace the
fan
Lower the ambient temperature
Check and reconnect the control
board

5.4 Function parameter list
The function parameters are divided into groups by function, and each group includes several function codes (each
function code identifies a function parameter). A three-level menu style is applied to function codes. For example,
"P00.08" indicates the 8th function code in the P0 group. The P29 group consists of factory function parameters, which
are user inaccessible.
