6. HOW TO USE INDEXER
6 - 12
6.2.3 Automatic operation mode 2 (shortest rotating indexer)
This operation mode automatically changes a rotation direction to the shortest distance to execute
positioning to a station.
The positioning is executed by selecting a station No. using 8-bit devices of the DI0 (Next station No.
selection 1) to DI7 (Next station No. selection 8). For the servo motor speed and acceleration/deceleration
time constant during operation, the values set in the point tables are used.
(1) Device/parameter
Set input devices and parameters as follows.
Item Used
device/parameter
Setting
Selecting indexer method
Control mode selection of [Pr. PA01
Operation mode]
Select "_ _ _ 8" (positioning mode (indexer
method)).
Next station position
DI0 (Next station No. selection 1) to
DI7 (Next station No. selection 8)
Set any next station No. (Refer to (3) of this
section.)
Automatic operation mode 2
(shortest rotating indexer)
selection
MD0 (Operation mode selection 1)
Switch on MD0.
MD1 (Operation mode selection 2)
Switch on MD1.
Servo motor speed
SIG (External limit/Rotation direction
decision/Automatic speed selection)
The servo motor speed will be as follows.
Off: setting value of [Pr. PC05 Automatic operation
speed 1]
On: setting value of [Pr. PC06 Automatic operation
speed 2]
Acceleration time
constant/Deceleration time
constant
RT (Second acceleration/deceleration
selection)
1. Turning off RT will be as follows.
Acceleration time constant: setting value of [Pr.
PC01 Acceleration time constant 1]
Deceleration time constant: setting value of [Pr.
PC02 Deceleration time constant 1]
2. Turning on RT will be as follows.
Acceleration time constant: setting value of [Pr.
PC30 Acceleration time constant 2]
Deceleration time constant: setting value of [Pr.
PC31 Deceleration time constant 2]
(2) The other parameter setting (number of stations)
Set a number of stations to [Pr. PT28]. The setting is the same as that of automatic operation mode 1.
Refer to section 6.2.2 (2) (b).
[Pr. PA14 Rotation direction selection] is not used in the automatic operation mode 2.
