3.2. Electrical Specifications
The electrical specifications and connector P1 pinouts for all BA drive models are listed
in Table 3-2.
Model
Brushless:
- single current command with on-board 6-step commutation from HED inputs.
- dual phase commands with sinusoidal commutation provided by an external
motion controller, third phase command is derived from the amplifier.
- velocity command with 6-step commutation from HED inputs and velocity
feedback from the tach or encoder.
Brush:
- single current command.
- velocity command with velocity feedback from the tach or encoder.
- +input-Pin 8, -input-Pin 21: Differential inputs for current or velocity commands,
0 to 10 VDC input. "+input" (non-Inverting input) can be used in single ended
fashion. A positive voltage on this input causes CCW motor rotation. "-input"
(inverting input) can be used in single ended fashion. A positive voltage on this
input causes CW motor rotation.
- icmda-Pin 9, icmdb-Pin 22: Dual phase, 10V input. ICMDA (current command
A) and ICMDB (current command B) are jumper selectable current command
inputs. They bypass the differential input, pre-amplifier, and self-commutation
circuit. They are to be used with controllers that provide external velocity loop and
commutation control.
