Stepper Motor
Outputs
The stepper motor demand outputs are digital output drivers which are opto-
isolated. The outputs are arranged in four groups for the three positional axis
drives and the fourth output is used in the multiplexer drive circuit.
Their functions are as follows:
• STEP Step pulses to the stepper drive cards
• DIR Direction of rotation to stepper drive cards.
• BOOST Not used
The outputs are routed to their respective stepper drive cards or via the
multiplexer card to drive the individual motors.
An example of the digital output for the stepper motor system is shown below:

NextMove
Breakout
The NextMove card passes signals through the 100 way breakout backplane
known as the NextMove Breakout. The breakout is situated on the rear
connector panel as shown below. DEK provide a breakout service tool which
plugs into either M19PL15 or M19PL17 it enables monitoring of the 100 Way
connector M19SK16 which has all the encoder, analog and digital signals
directed to it.

Service Tool The NextMove breakout service tool has screw terminals to enable easy
connection of test equipment to the 50 way breakout connectors M19PL15 and
M19PL17. This tool is used to enable all the signals available on the breakout
board sockets to be accessed for monitoring. Plug M19PL15 connects to all of
the odd numbered pins (1 through to 99) in connector M19SK16 whilst plug
M19PL17 connects to the even numbered pins of M19SK16.
