5. OPERATION
(4) Automatic continuous operation
(a) What is automatic continuous operation?
By merely choosing one point table and making a start (RYn1 or RYn2), operation can be performed in
accordance with the point tables having consecutive numbers.
Automatic operation is available in two types: varied speed operation and automatic continuous
positioning operation.
Either type may be selected as follows.
1) In absolute value command specifying system
Automatic continuous
operation
2) In incremental value command system
Automatic continuous
operation
(b) Varied speed operation
Speed during positioning operation can be changed by setting the auxiliary function of the point table.
Use the number of point tables equal to the number of speeds to be set.
By setting "1" to the auxiliary function, operation is performed at the speed set in the next point table
during positioning. The position data valid at this time is the data selected at start and the acceleration
and deceleration time constants of the subsequent point tables are made invalid.
By setting "1" to the auxiliary function of up to point table No.254, operation can be performed at a
maximum of 255 speeds. Set "0" to the auxiliary function of the last point table.
When performing varied speed operation, always set "0" to the dwell. If "1" or more is set, automatic
continuous positioning operation is made valid.
The following table gives a setting example.

Note 1. Always set "0".
2. Always set "0" or "2" to the auxiliary function of the last point table among the consecutive point tables.
POINT
This function is valid when the point table is selected using the input signal or
the RY of CC-Link. It cannot be used when the point table No. is selected
using the remote register of CC-Link.
