Alarm
Background
code
24 V DC supply
is connected
This alarm may
occur when the
motor is running
This alarm may
occur when the
motor starts
running
A42
A43
This alarm may
occur when the
24 V DC supply
is connected
The motor does
not rotate or
reversely rotates
if the command
pulse is input
after DC-link
and mains line
are connected
This alarm may
occur when the
motor is running
A44
This alarm may
occur when the
24 V DC supply
is connected
36
Possible Cause
The encoder fails
The encoder fails
The encoder cable is badly
connected
1. terminals U, V, and W on
the motor are wrongly
connected
2. the encoder is wrongly wired
Ambient temperature is too high
The drive is overloaded
Circuit board fails
1. terminals U, V, and W on
the motor is wrongly
connected
2. encoder cable is wrongly
connected
Encoder fails
The maximumly-permitted
following error is too small
The position loop gain is too
small
No enough torque
Low speed
Command pulse frequency is
too high
Circuit board fails
Remedy
Replace the drive with a
new one
Replace the drive with a
new one
Replace the drive with a
new one
Check the wiring
Check the ambient
temperature
Check the drive load
Replace the drive with a
new one
Replace the drive with a
new one
Check the wiring
Replace the motor with
a new one
Set a wider value range
for the detection of
following error (P34)
Give more gains
Check the limit value of
current
Reduce the load
Use a drive and motor
with bigger power
Check the maximum
speed limitation (refer to
parameter P26)
1. Lower the frequency
2. Check whether P36
has the right value
Replace the drive with a
new one
