AL.004 Driver Over Current CiA402 Error Code 0x2310-02-0004
Alarm Cause
The primary circuit current of the Driver exceeds the protection range, and results
in Power Transistor generating Error Alarm directly.
1. Incorrect primary circuit or encoder wiring or bad connection.
2. Internal short circuit of the servo driver, servo motor or primary circuit wires.
3. Incorrect regenerative resistor wiring or bad connection.
4. Cn030 Setting error.
5. Control Parameter Setting Error.
6. Malfunction caused by the noise.
7. Power Transistor Error.
8. Driver hardware failure.
Check and
Handling
1. Check if the Motor Terminal wiring (U, V, W) and Encoder wiring is correct;
please wire in accordance with Chapter 2 Servo Driver Power and Peripheral
Wiring Diagram.
2. Check if the servo unit and servo motor as well as connection terminal U, V, W
& FG are short-circuited.
3. Check if the regenerative resistor wiring is correct.
4. Please confirm if Cn030 is the correct motor/driver matching; please refer to
“Servo driver and servo motor matching comparison table” for Cn030 motor
code.
5. Execute countermeasures of anti-noise, such as install FG wiring correctly.
6. Driver error; please send the device back to the distributor or manufacturer to
overhaul.

AL.005 Encoder Signal Error CiA402 Error Code 0x7305-01-0005
Alarm Cause
Motor Encoder malfunction or poor connection of Encoder power line.
1. Encoder damaged.
2. Encoder wire loose or damaged.
3. Encoder motor code Cn030 setting error.
4. Encoder signal acquisition error.
Check and
Handling
1. Please send the device back to the distributor or manufacturer for overhaul.
2. Check if the encoder wire is connected to the driver, short-circuited, cold-
welded or falls out.
