(Table 7.1)
Alarm No.
Alarm Name
Failure Diagnosis
1
Overspeed
The speed of the servo motor exceeds the set value.
2
Main circuit overvoltage
The voltage of three-phase or two-phase power supply is too high or the brake
fails to work.
3
Main circuit undervoltage
The voltage of three-phase or two-phase power supply is too low.
4
Positive overproof
The value of the position deviation counter exceeds the set value and or the
voltage is too low.
5
Motor overheat
The temperature of the motor is too high.
6
Motorstalling
The motor is jammed and unable to rotate freely, or the load is too great.
7
Driver disablement abnormal
CCW and CW has no input or Parameter Pa20 is not 1.
8
Position deviation counter overflow
The absolute value of the value of the position deviation counter exceeds 230.
9
Encoder failure
The signal of the encoder is incorrect.
10
Software failure
The chip of the circuit board fails.
11
IPM module failure
IPM intelligent module fails.
12
Overcurrent
The current of the motor is too great.
13
Overload
The driver and the motor overloads (instantaneous overcurrent ) and are unable
to rotate freely.
14
Brake failure
The braking resistor or circuit fails.
15
Encoder count incorrect
Encoder count abnormal.
16
Motor thermal overload
The electric thermal value of the motor exceeds the set value.
17
Speed response failure
Speed error is too great for a long time.
19
Hot reset
The system is hotly reset.
20
EEPROM failure
EEPROM incorrect.
23
Housing electric leakage failure
External short circuit or the motor leakage
29
User torque overload alarm
The load of the motor exceeds the value and duration set by the user.
30
Encoder Z-pulse loss
Encoder Z-pulse incorrect.
31
Encoder UVW signal broken
Encoder UVW signal is incorrect or not matched to the encoder.
32
Encoder UVW signal interference
All-high electrical level or all-low electrical level exists in UVW signal.
