To Next PageTo Next PageWhy is my Vexta PMC Engine not rotating when I input a pulse signal?
If your Vexta Engine isn't rotating upon pulse signal input, ensure the pulse signal remains in the 'photocoupler OFF' state. Also, verify that you've connected the pulse signal to the correct pulse/CW pulse signal input terminal.
What to do if my Vexta Engine rotates in the wrong direction?
If your Vexta Engine rotates in the wrong direction, connect the CW pulse signal line to the pulse/CW pulse signal input terminal, and connect the CCW pulse signal line to the rotation direction/CCW pulse signal input terminal. Also, double-check the rotation direction signal levels, keeping in mind that 'photocoupler ON' corresponds to clockwise rotation and 'photocoupler OFF' to counterclockwise.
How to troubleshoot no excitation in Vexta PMC?
If there's no excitation in your Vexta Engine, start by checking the power supply connection if the POWER LED isn't lit. If the all windings off signal is active, the motor will lose excitation, so ensure this signal is set to 'photocoupler OFF'. Check the wiring configuration and connector continuity. If lead wires have been extended, inspect the extension connection. If these steps don't resolve the issue, contact your nearest sales office for service.
