[Md.108] Servo status1
This area stores the servo status1.
 • READY ON: Indicates the ready ON/OFF.
 • Servo ON: Indicates the servo ON/OFF.
 • Control mode: Indicates the control mode of the servo amplifier.
 • Servo alarm: Turns ON during the servo alarm.
 • In-position: The dwell pulse turns ON within the servo parameter "in-position".
 • Torque limit: Turns ON when the servo amplifier is having the torque restricted.
 • Absolute position lost: Turns ON when the servo amplifier is lost the absolute position.
 • Servo warning: Turns ON during the servo warning.
Refresh cycle: Operation cycle
■Reading the monitor value
 • Monitoring is carried out with a hexadecimal display.
 • When the forced stop of controller and servo amplifier occurs, the servo warning is turned ON. When the 
forced stop is reset, the servo warning is turned OFF.
 • Confirm the status during continuous operation to torque control mode with "[Md.125] Servo status3".
 • Buffer memory address
Refer to the following for the buffer memory address in this area.

[Md.109] Regenerative load ratio/Optional data monitor output 1
 • The rate of regenerative power to the allowable regenerative power is indicated as a percentage.
 • When the regenerative option is used, the rate to the allowable regenerative power of the option is indicated.
(Buffer memory) %
 • This area stores the content set in "[Pr.91] Optional data monitor: Data type setting 1" at optional data monitor data type 
setting.
Refresh cycle: Operation cycle
■Reading the monitor value
