12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
12 - 81
(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.
(a) Device/parameter
Set input devices and parameters as follows:
Item
Device/parameter to be used
Setting
Selecting indexer method
Control mode selection of [Pr. PA01]
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) (c) in 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. When RT is turned off
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. When RT is turned on
Acceleration time constant: setting value of [Pr.
PC30 Acceleration time constant 2]
Deceleration time constant: setting value of [Pr.
PC31 Deceleration time constant 2]
(b) The other parameter setting (number of stations)
Set the number of stations with [Pr. PT28]. The setting is the same as that of automatic operation
mode 1. Refer to section 12.6.2 (2) (b) 2).
[Pr. PA14 Rotation direction selection] is not used in the automatic operation mode 2.
(c) Operation
Select a target station No. using 8-bit devices of the DI0 (Next station No. selection 1) to DI7 (Next
station No. selection 8) for positioning.
