 Alarms
 Bit 0: Servo Driver Error
0: No SERVOPACK alarm.
1: SERVOPACK alarm occurred.
This bit changes to 1 when an alarm occurs in the SERVOPACK.
You can view the details of the alarm in the IW2D monitor parameter (SERVOPACK Alarm
Code).

Bit 1: Positive Overtravel
0: No positive overtravel.
1: Positive overtravel occurred.
This bit changes to 1 when a positive overtravel signal is input and a travel motion command is
executed in the forward direction.

Bit 2: Negative Overtravel
0: No negative overtravel.
1: Negative overtravel occurred.
This bit changes to 1 when a negative overtravel signal is input and a travel motion command is
executed in the reverse direction.
 Bit 3: Positive Software Limit
0: Positive software limit not exceeded.
1: Positive software limit exceeded.
This bit changes to 1 when a travel command is executed that exceeds the positive software
limit in the following situations.
• When bit 0 (Axis Selection) in fixed parameter No. 1 is 0 (Finite-length axis).
• When the positive software limit is enabled.
• When the origin return operation is completed.
Refer to the following section for details.

 Bit 4: Negative Software Limit
0: Negative software limit not exceeded.
1: Negative software limit exceeded.
This bit changes to 1 when a travel command is executed that exceeds the negative software
limit in the following situations.
• When bit 0 (Axis Selection) in fixed parameter No. 1 is 0 (Finite-length axis).
• When the negative software limit is enabled.
• When the origin return operation is completed.
