MODE SELECT Selects the operation mode
AUTO ---- automatic mode
MANUAL ---- manual mode

JOG SELECT Selects the jog method to be active in manual mode
HANDWHEEL ---- HPG (hand pulse generator) jog
INCREMENTAL ---- incremental jog
CONTINUOUS ---- continuous jog
HOME ---- machine home
SPEED/MULTIPLY Selects an axis feedrate or axis feed amount multiplication ratio used in the manual mode. Each
selection modifies the active feedrate by a value set in AMP. Modification also depends on the setting
of <JOG SELECT> as described below:
• HANDWHEEL
When in handwheel jog mode, SPEED/MULTIPLY alters the handwheel resolution by a factor
determined in AMP. Your system installer sets the value for:
- LOW X1
- MEDL X10
- MEDL X100
You cannot use the values listed below for handwheel jog:
- MEDH X1000
- HIGH X10000
• INCREMENTAL
When in incremental jog mode, SPEED/MULTIPLY alters the incremental jog distance by a factor set
in AMP by your system installer. Your system installer sets a value for the selections. The
incremental jog speed is fixed to medium but can still be controlled by
<FEEDRATE OVERRIDE>.
• CONTINUOUS
When in continuous jog mode, SPEED/MULTIPLY acts as a feedrate selection switch which has
values set in AMP by your system installer. Your system installer sets a value for all 5 selections
independently for each axis. <FEEDRATE OVERRIDE> can be used for speed adjustments.
Important: The values for the different <SPEED/MULTIPLY> selections are configured by
your system installer.
