Minimize Interference from Electrical Noise with Correct Shielding and Grounding Chapter 4

Important: Connect PS output commons togerther.

Connect the following to earth ground: a) cable shields (except for amplifier outputs) at one end only

b) input terminal 4, c) case grounds of PS and amplifier, e) LDT flange.

Operate the Module for the First time Chapter 5

After

loading profiles with the ladder program (step 1), alternately

run the extend profile (O:e.0/0 = 0-to-1),

then the retract profile (O:e.0/1 = 0-to-1).

Modify the profile to reach the preset reference, and set it.

Important:

If motion is reversed: for a

10V dc output, change the sign (

) of all extend/retract voltage

values; or for a +10V output, energize the other solenoid on the directional valve (with ladder logic).
