3.3.3 Pulse Train Input Operation
[1] Command Pulse Input (PP•/PP, NP•/NP)
Pulses of up to 200kpps in the open-collector mode or up to 2.5Mpps in the differential mode
can be input.
6 types of command pulse train can be selected. Set the pulse train format in Parameter No.63
and active high/low in Parameter No.64.
[Refer to 3.3.4 Settings of Basic Parameters Required for Operation]
Caution:
(1) The directions in which the actuator moves upon receiving forward and reverse pulses
conform to the pulse count direction set in Parameter No.62.
(2) As for the forward/reverse directions, pay attention to the host controller setting or
PPï½¥/PP and NPï½¥/NP connections.
(3) Set the actuator acceleration/deceleration on the host controller side.
(4) The actuator acceleration/deceleration should not exceed the rated
acceleration/deceleration of the applicable actuator. [Refer to the actuator’s catalog or
the appendix in this Instruction Manual for the rated acceleration/deceleration of each
actuator.]
* The rotating direction of the motor is defined so that the counterclockwise direction
as viewed from the end of the load shaft represents the forward direction.
