Calculating Rotation Speed and Angle
You may also want to calculate the motor rotation speed and rotation angle, before commanding any
motion. If the pulse frequency and counts are known, they can be calculated as follows:
Rotation Speed (RPM) = 60 * Pulse (Step) Frequency / (Pulses/Revolution)
Rotation Angle (
°
) = 360 * Pulse (Step) Counts / (Pulses/Revolution)
Rotating the Motor via the On-board HMI
User
’
s can rotate the motor by the on-board HMI for test purpose. A motion generator has been built
inside the drive. To start the motion, first you need to setup the motion parameter such as motion
velocity, motion distance, acceleration and initial direction, etc. The detailed steps are shown in the
following picture.
