Actuonix/Firgellie Linear Actuator L12 -P series working current

Help & Support Robot Parts

Hi all,

I am using the Actuonix linear actuator (L12-100-210-6P) with the LAC control board and I want to measure the practical working current of the actuator.

Anyone knows on which wire I should measure the current? Should it be the red wire (the wire in the middle)?

Many thanks.

Hi there,

Welcome on the forum.

Be sure to follow this picture to properly measure the current: Current-Measurement

In your case, the load is the red wire of the actuator. Make sure your not measuring in parallel but in serie with your amp-meter.

Let me know if this help.

Hi pjutras,

Thanks for the reply.

The only reason I am asking is for this particular actuator (—P version actuonix actuator), it has five wires and I am not exactly sure how the actuator is controlled and what are the other wires used for (it is not like a servo motor, which has three wires). So, I guess it should be the red wire and want to confirm that.

I understand your question now.

Thank you for the clarification.

Your actuator is probably one with an Option P which means a Potentiometer Position Feedback.
This is why it has 5 wires.

Orange: Feedback Potentiometer negative reference rail
Purple: Feedback Potentiometer wiper
Red: Motor V+
Black: Motor V-
Yellow: Feedback Potentiometer positive reference rail

This information was found in this datasheet at page 2: https://www.robotshop.com/media/files/pdf/L12_Datasheet-2.pdf
