QUICK LOAD SERVO 65/80
1 - 3 3
Display Name
Definition
Cause
Action
1. Acceleration/deceleration time
constant is too small.
Increase the acceleration/deceleration
time constant.
2. Internal torque limit 1
(parameter No.28) is too small.
Increase the torque limit value.
3. Motor cannot be started due to
torque shortage caused by power
supply voltage drop.
1. Review the power supply capacity.
2. Use servo motor that provides larger
output.
4. Position control gain 1
(parameter No.7) value is small.
Increase set value and adjust to ensure
proper operation.
5. Servo motor shaft was rotated
by external force.
1. When torque is limited, increase the
limit value.
2. Reduce load.
3. Use servo motor that provides larger
output.
6. Machine struck something.
1. Review operation pattern.
2. Install limit switches.
7. Encoder faulty
Change the servo motor.
AL.52
Error excessive
The droop pulse
value of the
deviation counter
exceeded the
encoder resolution
#
10 [pulse].
8. Wrong connection of servo
motor. Servo amplifier's output
terminals U, V, W do not match
servo motor's input terminals U, V,
W.
Connect correctly.
1. Communication cable
breakage.
Repair or change communication cable
2. Communication cycle longer
than parameter No. 23 setting.
Set correct value in parameter.
AL.8A Serial
communication
time-out error
RS-232C or RS-
422 communication
stopped for longer
than the time set in
parameter No.23.
3. Wrong protocol.
Correct protocol.
1. Communication cable fault
(Open cable or short circuit)
Repair or change the cable.
AL.8E Serial
communication
error
Serial
communication
error occurred
between servo
amplifier and
communication
device (e.g.
personal
computer).
2. Communication device (e.g.
personal computer) faulty
Change the communication device
(e.g. personal computer).
88888
Watchdog
CPU, parts faulty
Fault of parts in servo amplifier
Checking method
Alarm (88888) occurs if power is
switched on after disconnection of
all cables but the control circuit
power supply cables.
Change servo amplifier.
