MultiMove Block
Diagram
The MultiMove cards are controlled via the CAN network by the NextMove
cards.

NOTE
1. JP1 is a link to DIG IN 9 and it is fitted to the MultiMove Backplane. The
machine software interrogates this function and determines the correct machine
software to run. This link should not be removed.
2. See the MultiMove tables for a complete listing of the MultiMove inputs and
outputs.
CAUTION
ANTI-STATIC HANDLING.
Standard precautions must be adhered to when
handling electronic cards and configuring and inserting into the enclo-
sures.

Universal Drivers The universal drivers described below form the basis for both the totem and
source drive outputs.
The PBD 3548/1 device is a source driver which has an output stage that is
switched on or off according to the voltage at its input. A high input signal
switches the transistor off, if the input is left open then it is detected as a low
signal.
The PBD 3545/1 is a sink driver and it also has an output stage that is switched
on or off according to the voltage at its input. A low input signal switches the
transistor off, if the input is left open then it is detected as a high signal.
Totem Drivers The totem driver uses a pair of devices in a source/sink (totem pole) arrange-
ment. This configuration is used to drive the 24V motors using pulse width
modulated (PWM) techniques. To drive a motor in both directions ie, a transport
belt, a dual driver arrangement of the type shown below is used.
