NOTE: All even-numbered pins are connected to logic ground (DC ground).
Optional VM50
Adaptor
If you wish to use screw terminal connections for the 24 programmable I/O, Compumotor
offers the VM50 adaptor (p/n VM50). If you wish to use screw terminal connections for both
the 24 inputs and the 24 outputs, you will need two VM50 adaptors.
The pin numbers on the VM50's screw terminals correspond to the same pin outs on the
PROGRAMMABLE INPUTS and PROGRAMMABLE OUTPUTS connectors. The VM50 simply
attaches to the 6250 via the 2-foot, 50-pin ribbon cable that comes with the VM50 (see
drawing below).
To order the VM50, contact your distributor or ATC, or call Compumotor at [phone].

Trigger Input Connections
The 6250 provides two trigger (position latch) inputs. Like the programmable inputs described
earlier, trigger inputs can be connected to PLC outputs, discrete switches, or electronic sensors,
and are monitored under program control. The status of triggers A and B is represented
respectively by bits 25 and 26 in the [IN], INFNC, INLVL, ONIN, and TIN commands.
Using the WAIT command, the 6250 can be programmed to wait until one or more inputs
switch to a desired state before executing the next command.

Position Latch
Feature
The trigger inputs function identically to the regular 24 programmable inputs, except when
they are programmed with the Trigger Interrupt Function (INFNCi-H) command to function
as position latch inputs.
When configured as position latch inputs, the input enable/disable (INEN) command has no
effect on the trigger inputs. Note: The position latch feature is discussed in the Programmable
Inputs and Outputs section in Chapter 5)
