4. OPERATION
4.2.5 Automatic continuous operation
(1) What is automatic continuous operation?
By merely choosing one point table and making a forward rotation start (ST1) or reverse rotation start
(ST2), 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:
Point Table Setting
Automatic continuous
operation
Varied speed operation
Automatic continuous
positioning operation
Dwell time
Auxiliary function
0 1
1 or more 1
(2) 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 position
data and 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.14, operation can be performed at a
maximum of 15 speeds. Set "0" to the auxiliary function of the last point table.
When performing varied speed operation, always set "0" to the dwell time. If "1" or more is set,
automatic continuous positioning operation is made valid.
The following table gives a setting example:
Point Table No. Dwell Time [ms] (Note 1) Auxiliary Function Variable Speed Operation
1 0 1
2 0 1
3 0 0 (Note 2)
Consecutive point table data
4 0 1
5 0 1
6 0 1
7 0 0 (Note 2)
Consecutive point table data
Note: 1. Always set "0".
2. Always set "0" to the auxiliary function of the last point table among the consecutive point tables.
In the absolute value command system, the position data (addresses) of the midway point tables are
not used for positioning and speed is changed continuously to move to the set address in the last point
table.
In the incremental value command system, the position data is the total of the position data of the
consecutive point tables.
