ionship of PWM duty cycle to motor torque
Relat
•
Shaft torque increases in the CW direction as PWM duty cycle
decreases from 50% to 0%.
•
Shaft torque increases in the CCW direction as PWM duty cycle
increases from 50% to 100%.
•
As PWM duty cycle approaches 50% from either direction, motor
torque approaches 0.
•
O% and 100% duty cycle (static low and static high conditions) are not
valid PWM states. ClearPath interprets these values as zero-torque
commands.
•
PWM minimum on time and minimum off time = 300nS.
