Wiring between PMDX424 and Leadshine servo drivers M452

[3D_Companions]

Dear PMDXERS

I seek guidance in wiring a PMDX424 servo terminals J7 to J10 inc. to 4 off Leadshine servo drivers.

The PMX424 has 3 connection per jumper  which are COM, STEP and DIR. ( 12 leads in total )

The servo driver have 6 connections PUL+, PUL- , DIR+, DIR-, ENA+, ENA- ( 6 leads in total )

Can anyone confirm how they are to be wired?

See attachments

Thank you all in anticipation for a reply.

I will recommend running with COM used as ground, or
the negative side of your signals. To do this you will
need to set COM to be GND using our Mach4 plugin.
With Mach4 running, but not enabled, select:

Config > Plugins > PMDX-SmartBOB

and click on the tab labeled Motor Config. In top right of
the dialog will be an area for Step/Dir Common Configuration.
Click on the box for Step/Dir is Ground. This is the
default setting and should already be checked if
you have not edited anything.

It is also possible to operate with COM set to +5V
but we find it less confusing to use COM as Gnd with
modern drivers. Older drivers tended to use +5V as
COM because the old TTL logic family was better at
sinking current than at sourcing current. With CMOS
this is no longer a concern.

The COM terminal of the motor connector on the
PMDX-424 should connect to both the PUL- and to
the DIR- of the driver. The Step terminal of the motor
connector on the PMDX-424 should connect to the
PUL+ on the driver. The Dir terminal of the motor
connector on the PMDX-424 should connect to the
DIR+ on the driver.

You do not need any connection to the ENA+ and
ENA- terminals of the driver. The driver defaults to
enabled and these signals are only needed when
you need to disable the driver.

Just a note, your M542 drivers are for stepper
motors, not servos.
