•
Rise time is the time required (in milliseconds) for machine
movement to go from 10% to 90% of constant velocity.
•
T is the amount of time in seconds that the axis will travel in one
direction before it reverses for the same amount of travel in the
opposite direction. The actual distance depends on the feedrate
that corresponds to 0.9V.
NOTE:
Press
ClrFld
(
F1
) to erase the entry and enter another number.
4. Press
START
. The CNC generates an open-loop step response,
including rise time, in the Graphic Area of the screen.
5. Adjust the signal gain pot until the displayed feedrate is at 10% of the
machine’s maximum Rapid speed, using the fastest axis. The
machine builder sets the maximum Rapid speed in the Setup Utility.
6. Press
Manual
(
F4
) to cancel the test.

If the system has an ANILAM Servo Amplifier Board, you can make all of
the voltage measurements with the Servo Drive Test Board.
Measure command voltage across
TP1
and
TP2
of the test board. You
can find these signals also on Pins 3 and 11 of
J1
.
Measure the tachometer output across
TP2
and
TP3
of the test board.
You can find these signals also on Pins 5 and 11 of the
J1
input
connector on the ANILAM Servo Amplifier Board.
