How to clear the
alarm?
Condition: the Motor Parameter Identification Wizard function has not been executed
or the identification failed, and once the servo is on, this alarm is triggered.
Cause: a third-party motor has not executed the Motor Parameter Identification
Wizard function or failed to execute it.
Execute or re-execute the Motor Parameter Identification Wizard function.
Switch the servo to Servo Off to clear this alarm.
Condition:
1. Set value of PM.004 for the third-party rotary motor is not within the range of
128 - 268435456.
2. Set value of PM.004 for the linear motor exceeds 30000.
Cause: set value of PM.004 exceeds the allowable range.
Make sure the set values of PM.000 and PM.004 are correct.
Cycle power on the servo drive.
Condition: the difference between the monitored magnetic field returned by the Hall
sensor and the magnetic field calculated by the servo is too big.
Cause: when PM.009.Y 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.
Check if the Hall sensor is abnormal or has interference.
1.
Check if the feedback signal is abnormal. Use the software scope and select
2.
Feedback position [PUU] as the channel type to monitor whether the
feedback value is correct.
Check if the feedback signal has interference causing pulse leakage.
3.
If the encoder feedback type is a square-wave digital signal, check the
4.
following:
The motor is too fast and exceeds the maximum limit of the hardware.
(a)
The current limit of the hardware is 16 Mhz (the limit multiplied by
4 times the frequency).
When the encoder feedback type is a square-wave digital signal,
(b)
check if the filter setting of P1.074.U is appropriate.
Cycle power on the servo drive.
