Linear scale communication is cut off.
Make sure the wiring for the linear scale is correct.
DI.ARST
Analog input voltage for the speed command is higher than the level
specified by P1.083.
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.
DI.ARST
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.
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.
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.
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.
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.
Cycle power on the servo drive after the value is corrected.
