BL Installation and Configuration
2.7. Motor and Feedback Phasing
When configuring the BL amplifier to run a brushless motor, the commutation signal input connections
(labeled HALL A, B, C on connector J101 in velocity or torque command mode pins 4, 16, and 17) are nec-
essary. Two sequences of 30° or 0° (default) signal shift can be used, depending on the setting of jumpers
JP4, JP10, and JP12. These sequences and the generated output motor phase voltages (motor output con-
nections A, B, and C with respect to a real or pseudo neutral connection) are shown in Figure 2-12. The volt-
ages generated are made under the conditions of a positive signal placed at +INPUT with respect to -INPUT
at control signal input/output connector J101. A 0 for the given HALL input indicates zero voltage or logic
low, where a 1 indicates five volts or logic high.
N OT E : If an Aerotech brushless motor is used with the BL amplifier, motor phase and HALL connections
can be determined by referring to the system interconnection drawings in Figure 3-2, Figure 3-3, and Figure
3-4.
