6. If the follower drive needs to run at a different speed, adjust one or more of the following parameters:
Follower is running too slow: Increase P1-01, or Decrease P1-02, or set P1-03 to a positive number.
Follower is running too fast: Decrease P1-01, or Increase P1-02, or set P1-03 to a Negative number.
7. Optional Step: If desired, the pulse output from the PG-W2 card can be switched between the master
reference signal and the feedback signal by programming a Multi-Function Input Terminal (terminals 3 through
8, parameters H1-01 through H1-06) to a value of 80 or 81. Then a contact closure can switch between a
straight master/follower and a cascaded follower. Refer to the drawing on the page one of this instruction
manual. If no further programming is done, Follower “B” will follow the master reference encoder. If a multi-
function input is programmed and selected in Follower “A”, Follower “B” will follow Follower “A” instead of the
master reference encoder.
