Axis Operating Input Memory Areas Section 4-8
The functions of the bits shown in this table are applicable when the Position
Control Unit is connected to a G-series Servo Drive, a W-series Servo Drive
combined with a JUSP-NS115 MECHATROLINK-II Application Module, a W-
series Servo Drive with Built-in MECHATROLINK-II communications, or to a
SMARTSTEP Junior Servo Drive. The functions of Servo Status Flags 07, 08,
and 11 depend on whether position control, speed control, or torque control is
being used. (The SMARTSTEP Junior Servo Drive supports only position
control.)
Note The Servo Status Flags are used to monitor the control status of the Servo
Drive. The Servo Status Flags may not reflect the Servo status for short-term
changes in Servo Drive status, depending on the PLC cycle time and
MECHATROLINK communications cycle.
Servo ON Flag
Word b+1
Bit 03
Function ON while Servo Drive is in Servo lock status during position control or in
Servo ON status (Servomotor carrying current) during speed or torque con-
trol.
0: Servo unlocked (Servo OFF)
1: Servo locked (Servo ON)
This flag turns ON when the SERVO LOCK Bit (a+1, bit 00) in the Axis Oper-
ating Output Memory Area turns ON, and turns OFF when the SERVO
UNLOCK Bit (a+1, bit 01) turns ON or an error that sets the Servo in free run
state occurs.
Details Refer to 10-1 Servo Lock/Unlock .
Main Power ON Flag
Word b+1
Bit 04
Function Indicates the status of the main circuit power supply to the Servo Drive.
0: Main circuit power supply OFF
1: Main circuit power supply ON
Positioning Completed Flag (during Position Control)
Speed Conformity Flag (during Speed Control)
Word b+1
Bit 07
Function The function of these flags depends on whether position control or speed con-
trol is being used.
