Servo status
•
This area stores the servo status.
•
READY ON
Indicates the ready ON/OFF.
•
Servo ON
Indicates the servo ON/OFF.
•
Zeroing point pass
Turns ON if the zero point of the encoder has been passed even once.
•
In-position
The dwell pulse turns ON within the servo parameter “in-position.”
•
Zeroing speed
Turns ON when the motor speed is lower than the servo parameter “zero speed.”
•
Torque being restricted
Turns ON when the servo amplifier is having the torque restricted.
•
Servo alarm
Turn ON during the servo alarm.
•
Servo warning
Turn ON during the servo warning.
