•
This area stores the Software No. of the servo amplifier used.
•
When a servo parameter error occurs, the
bit that corresponds to the parameter
number affected by the error comes ON.
•
This area stores the servo status.
•
READY ON
Indicates the ready ON/OFF.
•
Servo ON
Indicates the servo ON/OFF.
•
Zero 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."
•
Zero speed
Turns ON when the motor speed is lower than the servo parameter "zero speed."
•
Torque limit
•
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.
•

as a percentage.
•
When the regenerative option is used, the rate to the allowable regenerative
power of the option is indicated.
