Command Function Description Example
HL Home Limit Action This command is used to set the action that
occurs when the limit switch is activated. If HL
is set to 0, the motor will continue to run after
switch activation but will send an "h" message
signifying home switch was triggered. If HL is
set to 1, the motor will stop immediately after
switch activation. HL 1
HN Hard Notify If HN is set to 1, it configures the motion
controller to send a serial message "h" once the
external limit switch is triggered. HN 1
HP Define External Switch
Polarity This command defines the activation edge of
the external switch. If HP is 0 a falling edge at
the external limit switch is valid. If HP is 1 a
rising edge occurs actions due to HL, HN and
HA-commands. HP 0
HS External Switch Status This command returns the state of the limit
switch. If the limit switch was active and an HS
request is sent, the controller will return a 1. If
the limit switch was not active since a HL, HN
or HA-command was sent an HS request will
return a 0 to the host. HS
