6. HOW TO USE INDEXER
(3) Timing chart
The following timing chart shows that a JOG 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)
Current station position
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. SIG and 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.
2. Counting will start when the rest of command travel distance becomes "0".
3. MEND (Travel completion) is off because the shaft does not stop within the in-position range of each next station position.
When MEND (Travel completion) turns off, PS0 (Station output 1) to PS7 (Station output 8) will not be outputted. Additionally,
the station position outputs will be "0" (all off) during home position return incompletion.
