SRC
Set external timebase

SRC sourcedef
Velocity Profile

LIMIT, RATCH
This command specifies the timebase for coordinated motion. The source can be defined
in any of the following formats:
sourcedef
description
NONE
CLOCK
ENC encoder
encoder
LIMIT limiter
RATCH ratchet
parameter
Disconnect device from source
Connect to servo clock ( 1 pulse per period )
Connect to encoder register
Connect to encoder register
Connect to frequency limiter output
Connect to ratchet output
Connect to user or system parameter
RES { preload }
REN
Reset or preload internal source count
Match internal source count to external input
During each servo interrupt, the change in source pulses is multiplied by the servo period
and the resulting delta time is fed into the velocity profile mechanism. By default, the
velocity profile is sourced off the CLOCK, feeding a single time unit per interrupt.
Redirecting the source allows an external timebase to be used for coordinated motion.
The following example sets source of the current master to ratchet number 5:
Usage example:
SRC RATCH5
