Rotating the Motor
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 / Micro Step Resolution
Rotation Angle (
°
) = 360 * Pulse (Step) Counts / Micro Step Resolution
Rotating the Motor by Motion Controller
You can start the controller or pulse generator to rotate the motor. Actually, any device which gives
high-to-low or low-to-high level changes can be used to move the motor. If it is your first time
installation, it is recommended to disconnect the motor shaft from the load in case of accident. You
can start from low pulse frequency then going to high. One triggered edge of the pulse makes the
motor move one micro angle. There are no minimum speed limits for the ES servos, however the
maximum running speed will be determined by the input voltage, current settings or maximum input
frequency of the drive.
Rotating the Motor in Self-test Mode
When the drive is configured in self-test mode by setting the SW2 to the ON position, the connecting
motor will rotates 1 revolution CW and 1 revolution CCW then repeat, until you set the SW2 to the
OFF position.
Rotating the Motor in PC Software
There is a simple emulating controller that is used for self-test in the ES-D drive. It is not a full
functionality controller, but it do eliminates the troubles to setup an external motion controller when
you want to test the ES drives or verify the connection in case of problem.
However, the
performance in the emulating controller DOES NOT represent that of using an external motion
controller
.
