exceeding
the max
torque
If send the command to move
into the distance beyond the
end of the structure
Checking the command of dis-
tance from host controller(PLC).
Fix the command of distance
to reasonable value.
It does not operate normal-
ly, because its deformable
structure
Checking the assemble status
of the equipment.
(Unscrews, debris, and
deformation structures)
Fix the assemble status of
the equipment.
It reaches end of
structure because S/W Limit
value is not set
Checking the S/W Limit value.
Fix the S/W Limit value to
suit to the equipment.
It reached end of
structure because
sensor of H/W Limit is not
operated
Checking whether H/W Limit
sensor working correctly.
Replace the H/W Limit ensor.
The load exceeding the Max
torque of motor
Checking whether motor has
enough torque by comparing to
load of instrument.
Lower the speed of opera-
tion. (Step motor generate high-
er torque when speed is low)
When is impossible,
replace the motor to higher
torque than load.
Motor does not operate
because motor is damaged
Checking whether motor is
damaged because motor
bearing damage. -> Pow-
er off the motor, and listening
to sound while rotate shaft of
motor by hand.
If find any damage, replace
the motor.
The drive may have problem
If Alarm keep blinking after
tried all of above, replace the
drive.

Over
Temperature
Inside
temperature of
drive exceeds
65℃
If the ambient temperature is
too high or the heating ele-
ment is near the drive
Checking the ambient tempera-
ture and make sure no heating
element near the drive.
Lower the room ambient
temperature to under 25℃, and
do heat dissipation by fan when
the temperature of the case is
over 50℃
Remove the heating element
from the drive.
Distance between drive is
below 50mm, so heat dissi-
pation is difficult
Make sure the distance between
drive is more than 50mm.
Keeping the distance more
than 50mm between drive.
If is impossible, do heat
dissipation by FAN.
The drive may have problem
If Alarm keep blinking after
tried all of above, replace the
drive.
6
Over Re-
generative
Voltage
Back-EMF of
motor
exceeds 40V
The acceleration and decel-
eration value is too small
Checking the Acceleration and
Deceleration conditions. (Differ-
ence depending on load and
speed)
Change the condition of
Acceleration and Deceleration.
Lower the operation speed of
motor relatively.
The drive may have problem
If Alarm keep blinking after
tried all of above, replace the
drive.
7
Motor
Connect
Error
An error with
the connec-
tion between
the drive and
the motor
The motor may have problem
Checking the disconnection of
motor phase.
(A and/A, B and/B)
Replace the motor.
If the motor cable between
motor and drive is damaged
Checking the connection of the
motor cable.
Fix the error after check
connection status of motor
cable.
Replace the extension cable
between motor and drive, if
there is problem.
The drive may have problem
If Alarm keep blinking after
tried all of above, replace the
drive.
