How do I read the feedback voltage from a DuraDrive actuator (MS4x / MS5x series) with MNL / MNB controllers

[Product_Support]

Issue

DuraDrive actuator feedback is 0-10 VDC or 2-10 VDC, controllers accept 0-5 VDC.

Environment

DuraDrive actuator (MS4x / MS5x series)

MNL / MNB controllers

Cause

The voltage feedback output was designed for controlling slave actuators configured for 0-10 VDC or 2-10 VDC control signals.

Resolution

Use two 10k resistors as a voltage divider across the feedback leads with the center point connected to the controller input and the actuator common connected to the controller common.

NOTE: Not all actuators in this product family use the wire colors shown for the feedback output. Please refer to the actuator GI sheet for the correct colors.

MNL / MNB Controller Analog Input Configuration For actuators with a 0 VDC to 10 VDC feedback output: Type= Volts Linput = 0 Lscale = 0 Hinput = 5 Hscale = 100 This input configuration provides a 0 - 100% output corresponding to the Actuator Position, based on feedback voltage 0 VDC = 0% and 10 VDC = 100% of actuator travel.  For actuators with a 2 VDC to 10 VDC feedback output: Type= Volts Linput = 1 Lscale = 0 Hinput = 5 Hscale = 100 This input configuration provides a 0 - 100% output corresponding to the Actuator Position, based on feedback voltage 2 VDC = 0% and 10 VDC = 100% of actuator travel.
