WIRING: Compound Motor Configuration
A specially configured controller is available for compound motor applications.
In this controller, the MOSFET output driver is used to drive the shunt field.
The wiring for a compound wound motor with armature reversing is shown
in Figure 4.

motor wiring diagram,

The configuration shown in Figure 4 requires the use of a compound wound
motor. Pure shunt motors cannot be used with 1207B controllers. Although
the configuration shown is typical, various other configurations are possible.
Note: The emergency reverse check feature (wiring shown by dashed line) is
a factory option.
