The relation between drive units, drive unit voltage, input
voltage, drive output, and interfacing to steering gear are shown
in Table 4-2 and Table 4-3. The AP50 system detects whether a
reversible motor or a solenoid is connected and outputs the
correct drive signal automatically.
Refer to the connecting diagrams for the different drive units on
pages 91 through 93.
Installation instructions for the drive units are found in the
manuals for the individual units.
The maximum drive current capabilities of the J50 and J50-40
Junction Units are different. Use the table below as a reference
and observe the notes.
