3.6.1. Position Synchronized Output (PSO)/Laser Firing (J201)

The PSO can be programmed to generate an output synchronized to the feedback position and is typically
used to fire a laser or sequence an external device. Trigger signals may be derived from a feedback channel
or a software trigger. The position synchronized output pulse is generated using high-speed hardware,
allowing minimal latency between the trigger condition and the output.

The PSO output is available on the dual-function AUX Marker/PSO signal lines. The auxiliary marker must
be configured as an output using the PSOOUTPUT CONTROL command. Refer to the Help File for more
information.

An RS-422 line receiver or opto-isolator is recommended, especially when using long cable lengths in noisy
environments or when high frequency pulse transmission is required. It is best to locate the line receiver or
opto-isolator close to the receiving electronics.

Use Aerotech's BB-MP wiring module to connect two drives for dual-axis PSO firing. The BB-MP module
will convert the AUX MARKER / PSO differential signal into other formats if required. It provides opto-
isolation, higher voltage operation, and can be used in sourcing or sinking output configurations. It also
simplifies the connection of encoder signals between axes that is required for two axis PSO operation. Refer
to the BB-MP manual for interconnection information.

1.

Signals in excess of this rate will cause a loss of PSO accuracy.

2.

The optocoupler that you use on the output might have an effect on this rate.

3.

MXH encoder multiplier options have an additional latency of ~3.25 microseconds between the measurement position and the

update of the PSO hardware.

N O T E :

 When using the MRK± signals with single-ended systems,

do not

connect MRK+ or MRK- to

GROUND (GND).

N O T E :

 The PSO feature is

not

compatible with the -MXU option. The PSO feature operates with the -

MXH option and with square wave encoders.

Software controlled PSO pre-scalars may be used to limit the data rate of each encoder being tracked
without affecting the servo loop data rate.
