Hi!
My lab partner and I are trying to connect a Standard Torque Motor (ST1) to a Phoenix Contact PLC using a Pulse Width Modulation module.
We are wondering if this has been done before, and If so what were the values you used for Voltage, Pulse, and Duty Cycle.
We are programming using PLCnext Engineer software. We have connected the yellow wire to the 5V pin on the PWM module. We are using a common ground. We have used an additional power source (5-7V) for the red wire (following the Lynxmotion pinout diagram) we have not wired the green wire as we are trying to run the servo in RC mode.
Thank you so much in advance for your help!

@Ashley_H If you want to use the ST1 as a normal RC (configurable) servo, you would need to change the mode from serial to RC either via the button menu or via serial configuration commands.
Regarding any connections, it’s likely best to look up to see if others have connected normal RC servos to the Phoenix Contact PLC. It’s critical that you understand how RC servo motors operate (including the purse and duty). For example: https://tutorial.cytron.io/2011/09/19/how-rc-servo-works/
The differences between a normal RC servo and the LSS include:
- Nominal voltage: 12VDC
- You can configure many parameters such as angle, speed, starting position and more.
You would only need to wire three connections:
- Black (GND)
- Red (12V)
- Yellow (PWM signal)
The green wire is as yet not connected in RC mode and is in place to allow anyone who prefers to use those more standard connectors in serial mode.
