6.1.5 /WARN (Warning) Signal
Both alarms and warnings are generated by the SERVOPACK. Alarms indicate errors in the
SERVOPACK for which operation must be stopped immediately. Warnings indicate situations
that may results in alarms but for which stopping operation is not yet necessary.
The /WARN (Warning) signal indicates that a condition exists that may result in an alarm.
Note: You must allocate the /WARN signal to use it. Use Pn50F = n.X (/WARN (Warning Output) Signal Allo-
cation) to allocate the signal to a connector pin. Refer to the following section for details.
6.1.2 Output Signal Allocations on page 6-8
Setting the Warning Code Output
You can use the ALO1 to ALO3 (Alarm Code Output) signals to output warning codes. Use
Pn001 = n.X (Warning Code Output Selection) to set the output.
Refer to the following sections for details on the warnings.
12.3.1 List of Warnings on page 12-48
6.1.6 /TGON (Rotation Detection) Signal
The /TGON signal indicates that the Servomotor is operating.
This signal is output when the shaft of the Servomotor rotates at the setting of Pn502 (Rotation
Detection Level) or faster or the setting of Pn581 (Zero Speed Level) or faster.
The /TGON signal is allocated to CN1-27 and CN1-28 by default.
Note: Use Pn50E = n.X (/TGON (Rotation Detection Output) Signal Allocation) to allocate the /TGON signal to
another connector pin. Refer to the following section for details.
