Drive unit installation
The relation between drive units, drive unit voltage, input
voltage, drive output and interfacing to steering gear are shown
in the table below. The AP20 system detects whether a reversible
motor or a solenoid is connected and outputs the correct drive
signal automatically.
Refer to the connecting diagram for the different drive units on
page 60 onwards.
Installation instruction for the drive units are found in the
manual for the individual units.
The maximum drive current capability of the J3000X, J300X
and J300X-40 junction units are different. Use the table below as
reference and observe the notes on next page.
