3.

Press the

button to reset the emergency stop

condition. If the E-Stop does not reset, it is a result of some cause
other then overtravel causing E-Stop.

4.

Make sure it is safe to move the axis away from the overtravel limit.

5.

Use any of the jog features described on page 4-1. This does not
include homing or jogging an offset. You are not allowed to jog the
axis in the direction of the overtravel.

This feature lets you disable the servo drives and move the axes by
external means, such as a hand crank attached to the ball screw, without
requiring the control to be in E-Stop. When you enable this feature, all
position displays get updated as the axes are moved.

You can use this feature in conjunction with the digitize feature described
in chapter 5.

You can only enable this feature when the control is in the cycle stop state
and the axes are not being jogged at the time of request. To use this
feature, it must be enabled in PAL by your system installer. See your
system installer’s documentation for details on how to activate and use the
“Mechanical Handle Feed” feature.

Use this feature to remove a rotary table or other axis attachment from a
grinder without reconfiguring the system. When activated, the control
ignores messages that may occur resulting from the loss of feedback from a
removed axis such as servo errors, etc.

Important: This feature removes the selected axis from the control as an
active axis. Any attempt to move the removed axis results in an error.
This means that part programs that use the removed axis name cannot be
executed. Jog moves and MDI commands that attempt to move the
removed axis also result in an error.

This feature can only be enabled in AMP. You must select the axis as
“detached.” See your system installer’s documentation for the necessary
steps involved in physically removing axis hardware from a specific
machine.
