4. Next PR command: if followed by a PR command, the arrow points to the
specified PR command.
5. Command information: displays the details of this PR command. The
color depends on the information types.
The following sections describe the display.
Homing PR Display
In the display of homing methods, PR#0 always signifies the homing procedure,
which is identified or indicated as "Homing". See
Figure 119 below.
Figure 119 - Homing Methods Display
1. Command execution type: to execute homing when the drive is in Servo
On state, it displays (B); if homing is not required, then no information is
displayed.
2. Method selection: homing methods and Z pulse setting are shown in the
table below. Characters in red (see
Figure 119 ) indicate the motor's
position after homing; F signifies running forward; R signifies running in
reverse; ORG signifies origin; CUR signifies current position; BUMP
represents the collision point.
