*Pulse train Selector PSB-F2A00


This is an optional Circuit Board suitable for driving VZθ Actuators.
The pulse train signals of Z axis and θ axis received from the host controller such as PLC are transmitted to each Motor Driver.
Normally, in the θ-axis operation of our VZθ Actuator, it is necessary to operate the 2-axis Motor synchronously, but this product is able to distribute the θ-axis pulse train (for 1 axis) to 2 axes and transmit the pulse train to the Motor Driver.
