6. HOW TO USE INDEXER
The following timing chart shows that an operation is performed at a stop of the station No. 0 when
servo-on.
Number of stations: 8
Power supply
ALM (Malfunction)
MEND (Travel completion)
PS0 (Station output 1) to
PS7 (Station output 8)
DI0 (Next station No. selection 1) to
DI7 (Next station No. selection 8)
Forward rotation
Servo motor speed 0 r/min
Reverse rotation
ST1 (Forward rotation start)
SIG
(External limit/Rotation direction
decision/Automatic speed selection)
RT
(Second acceleration/
deceleration selection)
MD0 (Operation mode selection 1)
MD1 (Operation mode selection 2)
Torque limit
Note 1. When the rest of command travel distance is other than "0", ST1 (Forward rotation start) will not be accepted. Refer to section
6.4.5 (1).
2. RT (Second acceleration/deceleration selection) will not be accepted during operation. Selection of the servo motor speed and
acceleration/deceleration time constants will be enabled by on-edge of ST1 (Forward rotation start). However, when the rest of
command travel distance is other than "0", turning on ST1 (Forward rotation start) will not be enabled.
3. Counting will start when the rest of command travel distance becomes "0".
4. When MEND (Travel completion) is off, the station position outputs will be "0" (all off).
