AL054 Parameter is out of range due to switching of motor types

Trigger condition

and cause

Condition: set value of PM.004 exceeds the allowable range.

Cause: set value of PM.004 exceeds the allowable range.

1. Check if the set values of PM.000, PM.003, PM.004, and PM.013 match the

Checking method

specifications of the connected motor.

and corrective action 2. If the issue persists, set P2.008 to 18 to reset the PM parameters and cycle

power on the servo drive.

How to clear the

alarm?

Cycle power on the servo drive.

AL055 Motor magnetic field error

Condition:

1. The difference between the monitored magnetic field returned by the Hall

sensor and the magnetic field calculated by the servo is too big.

Trigger condition 2. The detection occurs only when the linear motor speed is lower than

and cause

100 mm/s or the rotary motor speed is lower than 100 rpm.

Cause: when PM.009 [Bit 4] is set to 1, the servo detects the current magnetic field

position of the motor and compares it with the magnetic field position of the Hall

sensor. When the error between the two is too large, this alarm is triggered.

1. Check if the Hall sensor is abnormal or there is interference.

2. Check if the feedback signal is abnormal. Use the software scope and select

“Feedback Position [PUU]” as the input signal for the channel to monitor

whether the feedback value is correct.

Checking method 3. Check if the feedback signal has interference causing pulse leakage.

and corrective action 4. If the encoder feedback type is a square-wave digital signal, check the

following items:

How to clear the

alarm?

(a) Check if the motor speed is too fast and exceeds the maximum limit of

16 MHz that the hardware can receive (the limit is 4 times the frequency).

(b) Check if the filter setting of P1.074.U is set properly.

Cycle power on the servo drive.
