Use an initial value for
MC_4314
and
MC_4315
of 200 ms. Decrease
MC_4314
by 10 ms. until an overshoot is displayed when a rapid move is
commanded. When this occurs, increase
MC_4314
by 10 ms. until the
overshoot disappears. Repeat this for
MC_4315
when a feed move is
commanded. After the test has been run for all axes, use the highest
value obtained from all of the axes tested for the
MC_4314
and
MC_4315
values.
Use
MDI
(
F5
) to command moves. The step response and the resulting
overshoot percentage are displayed after the move ends. After
MC_4314
and
MC_4315
are adjusted, use
Save
(
F10
) to store the result.
I/O Monitor
This test displays manual panel inputs and PLC inputs and outputs to be
monitored while they are actually changed. PLC I/O is divided in
modules:
Module 0 is always present and represents the internal I/O (32 inputs
and 32 outputs).
Module 1 and so on represent external I/O modules (64 input, 32
outputs per module). They are automatically detected.
