Optional HOA Keypad Operation Chapter 6
The following state transition matrix summarizes the Jog/HOA behavior when
Parameter 45 “Keypad Mode” is set to 0 = maintained.
Note: In nearly all instances, if the processor detects multiple buttons are pressed
at the same time, the software interprets this as a “no button pressed” condition.
The only exception to this rule is if multiple buttons are pressed and one of them
is the “OFF” button. If the “OFF” button is pressed in combination with any
combination of other buttons, the processor will interpret this the same as if the
“OFF” button were pressed by itself.
Keypad and HOA Disable
Parameter 46 “Keypad Disable”, disables the “HAND”, “FWD”, “REV” and “Jog”
buttons on the HOA keypad. The “OFF” and “AUTO” buttons are always
enabled, even if Parameter 46 is set to “1=Disable”.
