AL041 Linear scale communication is cut off
Trigger condition
and causes
Linear scale communication is cut off.
Checking methods
and corrective
actions
Make sure the wiring for the linear scale is correct.
How to clear the
alarm?
DI.ARST
AL042 Analog input voltage is too high
Trigger condition
and causes
Analog input voltage for the speed command is higher than the level
specified by P1.083.
Checking methods
and corrective
actions
Check if the voltage source for the speed command is correct. Check the
setting value of P1.083 and set it to 0 when this function is not required.
How to clear the
alarm?
DI.ARST
AL044 Servo function overload warning
Trigger condition
and causes
Condition: when the motor controlling function of servo drive is overloaded,
the motion control function is affected, causing PR or E-Cam operation to
be in error.
Cause: Servo function overload warning.
Checking methods
and corrective
actions
1. Check if the filter is enabled and see if enabling the filter is necessary.
2. Set P2.066 Bit4 to 1 to disable this alarm.
How to clear the
alarm?
1. Disable the filter if it is not required, such as the low-pass filter (P1.006
– P1.008), moving filter (P1.068), low-frequency vibration suppression
(P1.025 – P1.028), vibration elimination (elasticity compensation,
P1.089 – P1.094), or Notch filter (5 sets).
2. Set P2.066 Bit4 to 1 and cycle power on the servo drive.
AL045 E-Gear ratio value error
Trigger condition
and causes
Condition: when the value of the E-Gear ratio exceeds the range (1/50 –
25600), this alarm occurs once power to the servo drive is cycled.
Cause: when the servo drive is powered on, E-Gear ratio value is in error.
Checking methods
and corrective
actions
Check if the value for the E-gear ratio is within the allowable range (1/50 –
25600). Correct the value and then cycle power on the servo drive.
How to clear the
alarm?
Cycle power on the servo drive after the value is corrected.
