17.3.2 Rotation direction specifying indexer
In this operation mode, the servo motor rotates in a fixed direction to execute positioning to a station.
Select a station No. with "Target point table" to execute positioning. For the servo motor speed, acceleration
time constant and deceleration time constant during operation, the values set in the object are used.
(1) Setting
Set objects and parameters as shown below.

selection
Turn off "Controlword bit 6 (Operation mode)".
Set the servo motor speed.
Acceleration time constant
Set the acceleration time constant.
Deceleration time constant
Set the deceleration time constant.
Set a speed limit value for during operation.
Positive torque limit value
Negative torque limit value
Set a torque limit value in operation.
Set a torque limit value in stop.
Set a time period for switching the torque limit
value in operation to in stop.
The torque limit will change from the setting value of "Torque limit value2" to the setting value of "Positive torque
limit value" or "Negative torque limit value" when "Controlword bit 4 (New set-point)" is inputted. After the output of
S_MEND (Travel completion) and the time set with [Pr. PT39] has passed, the torque limit will be switched from the
set value of "Positive torque limit value" or "Negative torque limit value" to the set value of "Torque limit value2".
