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 G5-series Servo Drive, a G-series Servo Drive,
a W-series Servo Drive combined with a FNY-NS115 MECHATROLINK-II I/F
Unit, a W-series Servo Drive with Built-in MECHATROLINK-II communica-
tions, 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.

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.
SERVO LOCK Bit
Servo ON Flag
SERVO UNLOCK Bit
