Servo unit internal IPM module failure occurs when power-on without enabling drive unit, short circuit exists between motor lines or braking resistor terminal, or the drive unit is faulty. The manual's first action is: “Remedy for reason A is to change to a new drive unit. Remedy for reason B is to check the correct the braking resistor connection.”

What Err-11 means
Servo unit internal IPM module failure p. 121
Common causes
- 1. It occurs when the power is ON, and the drive unit is not enabled. It cannot be removed after power-on. A. drive unit failure B. Short circuit occurs when braking resistor terminal is grounding. p. 121
- 2. It occurs when the power is ON, and the drive unit is not enabled. It is removed after power-on again. p. 121
- 3. It occurs when the power is turned ON, and the drive unit is enabled. It cannot be removed after power-on. A. short circuit occurs among motor power line U, V, W, or between U, V, W and PE. B. The drive unit IPM module is damaged. C. The sample circuit of the drive unit's current is OFF. p. 121
- 4. It occurs when the motor is starting or stopping and it can be removed after re-power-on. A. The default parameter of the motor set by drive unit is wrong. B. Then load inertia is too large; the commanded accelerated speed is too large during starting or stopping. p. 121
What to do
- Remedy for reason A is to change to a new drive unit. Remedy for reason B is to check the correct the braking resistor connection. p. 121
- It may be caused by external interference or poor grounding. Check the grounding status and interference source. p. 121
- The remedy for reason A is to change the motor line or the motor. The remedy for reasons B,C is to change the drive unit. p. 121
- The remedy for reason A is to restore the motor default parameter; The remedy for reason B is to increase the acceleration/ deceleration time, lower down the accelerated speed or load inertia. p. 121
