O peration of Master and Slave Axes
1 3 2 B
Operation of master and slave axes
Various positioning parameters should be set to perform operations on the positioning unit. The
parameters to be applied vary in the synchronous operation as follows.
Parameter name
Unit setting
Pulse number per rotation
Moving amount per rotation
Pulse I/O setting
Limit switch
Limit switch connection
Software limit (Positioning control)
Software limit (Home return)
Software limit (JOG operation)
Upper limit of software limit
Lower limit of software limit
Auxiliary output mode
Auxiliary output ON time (ms)
Auxiliary output Delay rate
Home return – Setting code
Home return – Direction
Home return – Acceleration time
Home return – Deceleration time
Home return – Target speed
Home return – Creep speed
JOG operation – Acceleration/Deceleration type
JOG operation – Acceleration time
JOG operation – Deceleration time
JOG operation – Target speed
JOG positioning operation setting code
JOG positioning operation acceleration time
JOG positioning operation deceleration time
JOG positioning operation target speed
Emergency stop deceleration time (ms)
Limit stop deceleration time (ms)
Error stop deceleration time (ms)
Pulser operation setting code
Pulser operation ratio numerator
Pulser operation ratio denominator
Stop function in synchronous operation
If the stop operation is executed for the master and slave axes during the synchronous operation, the
operation is as follows.
Stop operation
System stop
Emergency stop
Deceleration stop
Limit stop
Error stop
Operational overview
All axes stop without
deceleration time.
A specified axis stops with
a deceleration time.
Stops with a deceleration
time when a limit occurred.
Stop the operation with a
deceleration time when an
error occurs.
Operation during synchronous operation
Operates by the setting of each axis.
Specify the same settings for the axes to be
synchronized when performing the synchronous
operation.
Follows the operation of the master axis during the
synchronous operation.
Varies depending on the operation mode of the
synchronous operation.
Synchronous mode A: Operates by the setting of
each axis.
Synchronous mode B: Follows the operation of a
master axis.
Follows the operation of the master axis during the
synchronous operation.
The operation varies according to the type of stop
operations.
For the details, see the following "Stop function in
synchronous operation".
Operates by the setting of each axis.
Specify the same settings for the axes to be
synchronized when performing the synchronous
operation.
Axis requested to stop
Master axis
All axes stop.
Stops with the deceleration time for the master axis.
Stops with the deceleration time for the master axis.
After stop, the error code occurred on the master
axis is set for the master/slave axes.
Slave axis
