Steps/Rev

Default: 1
Range: 1 to 65535

This parameter is available on stepper axes only. It is used with the Pos Units/Rev parameter to determine the scaling between position units and steps output by the RMC. These steps can be interpreted by the stepper drive as either a full step or microstep.

The use of this parameter is summarized by the following equation, which is applied every control loop to convert the change in the Target Position to steps that are output.

As the name implies, the recommended value to enter in this parameter is the number of steps required to move the motor one revolution. Therefore, for a step motor with 48 steps per revolution and drive with 100 microsteps per step, you would enter a 4800 in this field. However, there may be times when you will not want to enter this value, but instead adjust this field in conjunction with the QUAD CNTS/REV and POS UNITS/REV fields.
