Isolated START, standoff inhibit (CSD) and motion
(OK-To-Move) signals are available at the Rear Panel
CNC (J40) connector or an internal terminal strip (J11).
The motion signal (OK-To-Move) may be selected to
be either a contact closure or 24 VAC switched
through the contact. The Standoff Control is factory-
set for 24 VAC operation. The purpose of selecting
24 VAC is to drive a relay coil whose current must
not exceed 150 ma.
NOTE
The 24 VAC may be required by some cutting ma-
chine controllers.
