CONTINUOUS ROTATION /
DISENGAGING MECHANICAL LIMIT
SWITCHES


The motor drive unit contains a mechanical limit switch
mechanism that is coupled to the encoder shaft inside the drive
unit. For continuous rotation it is necessary to disengage the
coupling per instructions below. This will then prevent the
mechanical limits from being engaged. The soft (electrical) limits
that are set on the 2090 remain functional and can still be used to
limit TT travel.

CAUTION All power must be turned off and locked out before
opening the drive unit.

CAUTION Exercise care when using the continuous rotation
feature so as not to damage user installed cables and equipment
mounted on the table.


A hex wrench and crescent wrench are required to disengage the
shaft coupling.

The capacitor above the coupling will need to be moved out of the
way by removing the mounting nut on the outside of the box. It can
then be shifted to the side.

There are two setscrews on the coupling of the 0.63 cm (0.25 in)
DIA shaft that drives the limit switch actuator inside the box.
Loosen these setscrews and push the coupling back on the shaft to
disengage it from the encoder shaft then tighten the setscrews
back. With the teeth disengaged the switches are now disabled.

The CW and CCW limit buttons on the 2090 will continue to
function at their settings.
