Alarm generated in the GSK driver (E**)

Code

Alerm names and detection contents

Cause of generation and treatment

E11

[IPM error] Power drive signal error (overcurrent / overheat / power supply error)
1. Short circuit between motor windings : Replace motor
2. Short circuit of motor connection cable : Replace cable
3. Controller drive circuit failure : Replace controller
4. Overheating due to overload
5. The ambient temperature of the controller is abnormally high

: Review the installation environment

6. Fan does not work : Replace controller

E21

[Overload] The motor average current exceeded the “overload alarm detection value” (see * 6-1)
1. Excessive load torque : Reduced load
2. Acceleration / deceleration frequency of operation is too high : Change of operation pattern
3.

Overload alarm set value is too small : “d00104” parameter change

4. Sensor setting error : Review parameters of “d00141”

E22

[Current control error] The average deviation of the current control loop exceeded
the "current control error value"
1. Motor disconnection : Replace motor
2. Broken motor connection cable : Replace cable
3. Occurrence of abnormal vibration : Readjustment of servo gain
4. Resolver NR is used : “d00114” parameter review

E31

[Overspeed] The motor speed exceeded the “overspeed alarm detection value”.
1. Excessive command speed : Review of command speed
2. Overspeed detection set value is too small

: “d00105” parameter change *

* There is a difference in initial value between NR and positioning.
Representative value NR : 15000 Positioning : 7500
Since the value varies depending on the model, please contact the manufacturer

for details.

3. Overshoot during control : Servo gain readjustment
4. After resetting the absolute position detection senso r: Reset the alarm again.

E41

[Position control counter overflow] Position data exceeds ± 68000000h
1. Rotated in a certain direction for a long time: Review of operation pattern
2. Does not move due to cable disconnection or wiring mistake: Cable replacement

E42

[Excessive deviation] Position deviation exceeded "deviation error detection value"
1. A large position command has been added in steps: Review of the position command
2. Motor disconnection: Motor replacement
3. Disconnection of motor connection cable: Encoder / resolver cable replacement
4. Abnormal vibration occurs: Servo gain readjustment
5. Setting error of angle sensor resolution: “d00141” parameter review

E61

[Sensor error] Encoder signal cannot be detected (disconnected)
1. Broken motor angle sensor connection cable : Replace the cable
2. Sensor setting error : Review parameters of “d00140”
3. Abnormal sensor attached to motor : Replace motor

E62

[Sensor abnormality] Abnormal sensor signal from resolver backup unit
1. After an error occurred, the power was turned off without resetting: Reset the R / D_board.
2. Resolver backup unit error : R / D_board replacement
3. Motor sensor magnetic pole signal error : Replace motor

E63

[Sensor error] Communication error with SmartInc or SmartABS encoder / resolver
1. Connection cable error: Replace cable
2. Resolver backup unit error: R / D_board replacement
3. Abnormal motor angle sensor: Replace motor

E64

[Sensor error] SmartInc or SmartABS encoder detected an error
1. Overflow count value overflow : Reset of multi-turn position data by alarm reset
2. Battery voltage drop : Replace battery after error reset
3. Cable breakage between resolver backup unit and resolver : cable replacement
4 Abnormal motor angle sensor : Replace motor
5. Malfunction of backup unit due to noise : Review cable connection and ground connection,

and install ferrite core on motor connection line

6. Uncertain origin

Return to origin

E65

[Sensor abnormality] There is no HZ state when the power saving encoder power is ON
1. Sensor setting error : Review parameters of “d00140”
2. Abnormal motor angle senso r: Replace motor
