- 195 -
set nonzero value, and the
actural output frequency
reaches the upper limit
frequency
Err.23
PID feedback
loss when
running
1. PID feedback less than
FA-26 set value
1. Check the PID feedback signal
or set the FA-26 to an appropriate
value
Err.24
Motor short
circuit to
ground
1. Motor short circuit to ground 1. Replace the cable or motor
Err.27
Running time
reached 1. Accumulative running time
reach to set value
1. Using parameter initialization
function to clear the record
information
Err.28
Power on
time reached 1. Accumulative power on time
reach to set value
1. Using parameter initialization
function to clear the record
information
Err.29
Buffer
contactor
overheating
1. Power grid voltage fluction
range is too large, cause the
inverter repeatedly up and
down, buffer contactor
overheating
1. Adding input reactor and other
measures to ensure the stability of
input voltage
Err.32
Encoder
reverse fault
1. Encoder phase sequence
and motor running in the
opposite direction 1. Change the encoder phase
sequence or exchange any two
phase of three-phase motor line
Err.35
User
self-define
fault 1
1. Through the multi-function
terminal DI input the signal of
user-defined fault 1
2. Through the virtual IO
function input the signal of
user-defined fault 1
1. Reset running
2. Reset running
Err.36
User
self-define
fault 2
1. Through the multi-function
terminal DI input the signal of
user-defined fault 2
2. Through the virtual IO
function input the signal of
user-defined fault 2
1. Reset running
2. Reset running
Err.37 Offload
1. The inverter running current
is less than F8-16
1. Confirm whether the load is out
of or F8-16, F8-17 parameter
settings are consistent with the
actual running condition
Err.38
Rapid
current-limitin
g timeout
1. Whether the load is too large
or motor stalling
2. Small frequency converter
selection 1. Reduce the load and check the
motor and mechanical conditions
2. Selection inverter with bigger
class power
Err.39
Switch motor
when running
1. In the process of inverter
running through the terminal to
change the current motor
selection
1. Switch motor operation after
inverter stop
