Direct Digital PWM Output

Having performed the following:
➢
Global Reset (optional but recommended).
➢
Set up the dominant clock frequencies.
➢
Unpacked the ADC input and phase output data.
➢
Verified encoder feedback.
Caution
The abort input must be wired in (+24 VDC) or disabled in software (Sys.pAbortAll = 0) prior to attempting
to enable the motor.
If the +24 VDC abort input is not wired in or is not disabled in software (Sys.pAbortAll = 0), PMAC will
try to close the loop on the motor every time it is enabled. This could prevent setting up a motor properly,
such as phasing manually or performing an open loop test
Motor and channel specific parameters can now be configured to finalize the setup procedure.
Note
Manual Motor Setup
If the +24 VDC abort input is not wired in or disabled in software
(Sys.pAbortAll = 0), PMAC will try to close the loop on the motor
every time it is enabled which could cause the motor the move or jump
(if it has not been set up).
A motor or channel parameter which is not discussed in the structure
elements below is assumed – and should typically be left – at default.
