Output Polarity

In most hydraulic systems, the actuator extends (with increasing

LDT counts) when a positive voltage is sent to the output. The

extend direction is defined as the direction that causes the LDT to

return increasing counts moving away from the head.

You can make these selections in the Config word that affect output:

• To generate a positive drive output (0-10V dc) regardless of move

direction, you can select Absolute Mode.

• To extend the actuator by sending a negative voltage to the

output, you can select Reverse Drive Mode.

For additional information on the Configuration word, select that

subject in Help Topics.

connected to the IFM terminal block.
