and Description
Corrective Actions

Method
09
Emergency Stop
1. Disable Emergency stop signal input.
2. Internal mal-function.
Ensure that all connection are
correct, refer to Chapter 2 Power and motor
circuit diagrams connection.
Control wiring diagrams.
Turn
ALRS
(DI)
ON
When the input contact point
EMC is activated. Alarm 09
appears.
10
Motor over-current
1. Check if the motor wiring U,V,W)and encoder
wiring correct or not.
2 .Internal interference and mal-function. Ensure
that all connection are correct refer to Chapter 2
Power and motor circuit diagrams.
Turn
ALRS
(DI)
ON
Motor current is 4 times greater
than rated current.
11
Position error 1. Increase the position loop gain (Pn310 and
Pn311) setting value.
2. Increase in position tolerance value by (Pn307)
for a better motor response.
3. Extend the time of ac/deceleration or reduce
load inertia in the permitted range.
4. Check if the motor wiring (U,V,W) is correct.
Turn
ALRS
(DI)
ON
The deviation between Pulse
command and encoder feed
back ( position error) is greater
than the setting of Pn308 or
Pn309.
12
Motor over speed 1. Reduce the speed command.
2. Electronic gear ratio is incorrect check and set
correctly.
3. Adjust speed loop gains (Sn211 & Sn213) for a
better motor response.
Turn
ALRS
(DI)
ON
Motor’s speed is 1.5 times more
then motor’s rated speed.
13
CPU Error Turn off the power. Turn on again after 30min. If
error alarm still exists, this may be due to external
interference. Refer to the chapter 2 Motor 、 power
cable and control signals connections.

Supply
Control system Mal-function.
14
Drive disable 1. Remove input contact signal
CCWL or CWL.
2. Check all input wiring for correct connections.
3. For the selected High /Low logic
potential settings refer to Section
5-6-1.
Turn
ALRS
(DI)
ON
When input contacts CCWL &
CWL are operated at the same
time this alarm occurs.
15
Drive overheat
Over-load for a long duration will cause driver
overheat, check and reset operation system.
Turn
ALRS
(DI)
ON
Power transistor temperature
exceeds 90°C.
16
Absolute Encoder Battery
error
Make sure if battery module is removed, power
supply is losing, or battery is power shortage and
requires replacing.
If the battery has reset, the number of turns
required to remove the encoder through Cn041
Turn
ALRS
(DI)
ON
Battery module remove or
battery voltage is lower than
3.2V
