The Servo lock status of each axis can be confirmed by checking the SVON
Flag in the Axis Operating Input Memory Areas.
Timing Chart
The following timing chart is for when SERVO LOCK and SERVO UNLOCK
are executed.
10-2 Jogging
10-2-1 Overview of Operation
The axis travels in the specified direction at the specified speed while the JOG
Bit is ON, and decelerates to a stop when the JOG Bit turns OFF. Jogging
operations can be executed even if the origin has not been established.
10-2-2 Procedure for Jogging Operations
The procedure for using jogging is as follows:
1,2,3...
1.
Set the Common Parameters and save them.
2.
Turn ON the PCU again or restart the Unit.
The data for the Common Parameters set in step 1 above is enabled.
3.
Start MECHATROLINK communications.

When SERVO UNLOCK is executed,
the PCU Positioning Completed Flag
turns OFF.
The status of the No Origin Flag and
Stop Execution Flag do not change
when SERVO UNLOCK is executed.
The SVON Flag turns ON/OFF when
the processing at the Servo Drive is
finished (e.g., reading absolute
encoder data, turning ON brake).
STOP Execution Flag
(word b, bit 15)
For details on the flag operations when using Servomotors with absolute encoders,
