(3) Rotational direction
The position where the origin return action is complete is the No. 1 station. At factory setting, the station numbers are allocated in the
increment direction of rotational direction. When the position preset is executed, the station numbers are allocated from its position in the
increment direction of rotational direction.
The station number is allocated from 1 up to the max. number of division of the basic para. 90 sequentially.
(4) Number of division
Basic parameter 90
Para. Name Setting range Initial value Change
90 Max. number of division 2 to 30000 (in 1 step) 8 Power
This para. specifies the number to divide the rotating object.
If the setting value is set to 2, positioning can be executed at the origin (No. 1 station) and the 180 degree opposite (No. 2 station).
If the [START] signal is used, indexing can be made within the range of less than one rotation.
In order to make a stop at the specified station number after rotating more than one revolution, use the manual indexing function.
See (7) of 5.3.1 Forward command [FWD]/Reverse command [REV].
(5) Backlash correct
The backlash of mechanical equipment system can be corrected by move amount of the motor shaft.
Basic parameter 86
Para. Name Setting range Initial value Change
86 Backlash correct 0 to 10000 [pulse] (in 1 step) 0 Always
After each change of the rotational direction of motor, the motor rotates by the amount added by the setting value.
(6) Specifying the rotational speed
The rotational speed depends on the on/off status of VEL1 and VEL0 signals. The speed can be changed even while motor is running.
Selection of rotational speed
VEL1 (13) VEL0 (12) Rotation speed
OFF OFF Basic para. 08
OFF ON Basic para. 09
ON OFF Basic para. 10
ON ON Basic para. 11
(7) Shorted route valid [DIR]
When the [START] signal is given while the [DIR] (7) is on, the motor rotates from the current station number to target station toward the
direction whose moving distance is shorter.
If the target station is just on the opposite side, the motor rotates in the direction in which the station number increases.
Where the max. number of division is four:
No. 1 station
No. 4 station
No. 3 station
No. 2 station
