5
Overheat
error
When driver
inner
temperature
is over 80℃
1. Installed in an enclosed
space
1. Change the installation
environment.
-Air flow around driver installation.
-Heat dissipation (heat sink or fan)
6
Motor
connec-
tion
error
When motor
cable
connection
error occurs
at driver
1. Motor connector and cable
connection error
2. Burnout of the inverter in
the driver 1. Check motor connector and cable
connection.
2. Replace burned parts of the
inverter in the driver.
7
Encoder
connec-
tion
error
When encoder
cable
connection
error occurs
at driver
1. Motor connector and cable
connection error
2. Burnout of line driver IC in
encoder 1. Check motor connector and cable
connection.
2. Replace the line driver IC in
encoder.
8
Regener-
ative
voltage
error When
regenerative
voltage is over
78V
1. Over load
2. Excessive force due to rapid
deceleration 1. Change operation condition or
reduce load so that sudden load
fluctuation does not occur.
9
Motor
mis-
alignment When motor is
in
misalignment
1. Motor connector and cable
connector error
2. Burnout of line driver IC in
driver
3. Burnout of line driver IC in
encoder
4. Burnout of the inverter in
the driver
1. Check motor connector and cable
connection.
2. Replace the line driver IC in driver.
3. Replace the line driver IC in
encoder.
4. Replace burned parts of the
inverter in the driver.
10
Command
speed
error
When
command
speed is over
3,500rpm
1. Enter error of user
command
speed input
1. Use recommended specifications.
(max. 3,000rpm input)
2. Enter the speed value (PPS) by
checking the resolution.
11
Input
voltage
error
When input
voltage is out
of 24VDC
±10%
1. Over load
2. Insufficient SMPS capacity
3. Power input over the
specification
(24VDC ±10%)
1. Change operation condition or
reduce load so that sudden load
fluctuation does not occur.
2. Check that less than the
recommended SMPS capacity is
used.
3. Check the power specification.
(24VDC ±10%)
12
In-
Position
error
When position
error (over 1)
is kept over 3
sec,
after motor
stopped.
1. Over load
2. Lack of stop torque.
1. Change operation condition or
reduce load so that sudden load
fluctuation does not occur.
2. Increase stop torque as 50% or
use the other motor with higher
torque.
13
Memory
error
When
memory error
is detected as
power
supplied
1. EEPROM error 1. Replace EEPROM parts.
