2.1. Introduction
This section covers the hardware configurations using the switches, jumpers, connectors,
and power hook-ups when used with a brush or brushless DC motor. Wiring, grounding,
and shielding techniques, an explanation of the current regulator adjustment, and the
motor phasing process are also covered in this section.
2.2. Jumper Selections
The BAL Series amplifiers are jumper selectable providing the user with quick
reconfiguration capability of operating modes. Table 2-1 lists the jumpers and the default
configurations for the amplifiers. Figure 2-1 highlights where the jumpers are located on
the board (with the default configurations).
Aerotech brushless motors should be set for 0 degree Hall commutation shift. Motors
from other manufacturers may require a 30-degree Hall commutation shift. Consult
the motor manufacturer for details.
