Part 1 Specification
(4) Operation at Different Acceleration and Deceleration
[1] When the controller is used in the positioner 1, 2 mode or simple direct mode, separate values can be set for
acceleration and deceleration using the position table.
[2] Direct numerical specification mode
In this mode, separate values cannot be set for acceleration and deceleration. The acceleration and deceleration are
always the same.
The acceleration/deceleration data (16-bit data) becomes effective when the data is received by the axis controller
(at the “0” (OFF) o “1” (ON) leading edge of the CSTR signal). To cause the actuator to decelerate at a different
value than the acceleration, change the acceleration/deceleration data while the actuator is moving.
(Example)
* Make sure “T1 t 0 ms” is satisfied by considering the scan time of the host controller.
