Background
Possible Cause
Remedy
Result
Acknowledgement
A short-circuit occurs to the
encoder
Check the wiring of
encoder
A21 This alarm may
occur when the
24 V DC supply
is connected
There is a failure at the circuit
board
Replace the drive with a
new one
Free stop Press the Enter key
on the operator
panel or terminal
RST of the X6
interface
This alarm may
occur when the
DC link is
connected
1. the mains supply voltage is
too high
2. the waveform of mains
supply voltage is abnormal
Check the power supply
This alarm may
occur when the
motor is running
1. disconnection of the internal
brake resistor
2. the internal brake resistor is
broken
Replace the drive with a
new one
Brake loop has no enough
space
1. lower the start-stop
frequency
2. minish the limit
value of current
3. minish load inertia
4. use another drive
and motor with
higher power
A22 The motor is mechanically
blocked
Check the mechanical
load
Free stop Press the Enter key
on the operator
panel or terminal
RST of the X6
interface
Overload
1. lighten the load
2. use another drive
and motor with
bigger power
A23
1. circuit board fails
2. fuse of the power is burnt out
3. rectifier is broken
Replace the drive with a
new one
Free stop Press the Enter key
on the operator
panel or terminal
RST of the X6
interface
1. low supply voltage
2. insufficient supply power
capacity
3. transient power failure
Check the power supply
A24 This alarm may
occur when it's
detected that
the difference
between the
position setpoint
and the position
actual value is
greater than
1000 pulses
when the drive
is in "S-2", "S-
3", or "S-4" state
There is pulse inputs at the
setpoint interface X5 when the
drive is in "S-2", "S-3", or "S-4"
state
When P38 = 1, check
whether more than
1000 pulses are
received at the setpoint
interface X5 when the
drive is in "S-2", "S-3",
or "S-4" state
Free stop Press the Enter key
on the operator
panel or terminal
RST of the X6
interface
There is shaft move when the
drive is in "S-2", "S-3", or "S-4"
state
When P38 = 1, check
whether the motor shaft
moves more than 1000
pulses when the drive is
in "S-2", "S-3", or "S-4"
state
A41 This alarm may
occur when the
Circuit board fails Replace the drive with a
new one
