6.1.4

/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.
Type
Output
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.
6.1.5

/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.
Type
Output
Note: You must allocate the /TGON signal to use it. Use Pn50E = n.X (/TGON (Rotation Detection Output)
Signal Allocation) to allocate the signal to a connector pin. Refer to the following section for details.
