Technical Specifications

2 axes with internal sinusoidal commutation (MC1231A)

1 axis with internal sinusoidal commutation (MC1131A)

Closed Loop (uses trajectory generator, servo loop, and commutation)

Open loop (uses commutation only)

-1,073,741,824 to 1,073,741,823 counts

-16,384 to 16,383 counts/sample with a resolution of 1/65,536 counts/sample

S-curve profile: -1/2 to 1/2 counts/sample^2 with a resolution of 1/65,536 counts/sample^2

All other profiles: -16,384 to 16,383 counts/sample^2 with a resolution of 1/65,536 counts/sample^2

-1/2 to 1/2 counts/sample^3, with a resolution of 1/4,294,967,296 counts/sample^3

S-curve (host commands final position, maximum velocity, maximum acceleration, and jerk)

Trapezoidal (host commands final position, maximum velocity, and acceleration)

Velocity contouring (host commands maximum velocity, acceleration)

Electronic Gear (Encoder position of one axis is used as position command for another axis).

32768:1 to 1:32768 (negative and positive direction)

PID+Vff (Proportional, Integral, Derivative + Velocity Feedforward and DC Offset)

PWM (10 bits resolution @ 24.5 Khz)

DAC (16 bits)

Sinusoidal
