Main Board terminals
4.9 Drive unit
The relation between drive units, drive unit voltage, input voltage, drive
output and interfacing to steering gear are shown in the table below. The
AP35 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
51
onwards.
Installation instructions for the drive units are found in the manual for the
individual units.
The maximum drive current capabilities of the J3000X and J300X junction
units are different. Use the table below as reference.
