Installation
All wiring and mechanical instructions described in this section should be made with reference
to the “Simplified Circuit Diagram” on page 7-2 and the “Outline, Mounting and Adjustments
Diagram” on page 7-1. Also see “Input Power/Motor Wiring” diagrams starting on page 2-4.
Internal Adjustments
Jumpers
There are jumpers on the velocity regulator board of the MAX-430 to indicate desired operation
of the Forward and Reverse Amplifier Clamps and the System Status Output (FAC, RAC, and
SSO). There are also jumpers used to indicate desired operation of the optically isolated tran-
sistors on FAC, RAC and inhibit (INH) inputs. Refer to Table 2.1 for operation of the inputs and
outputs with jumpers P6 through P9A in the different positions. Also see on “Forward and
Reverse Amplifier Clamps (FAC, RAC)” on page 2-10.
