Using Pro-Motion
3.2.8 Step #5: Initialize Stepper Parameters
This step of the axis setup wizard is used to select the stepper motor parameters. If this stepper motor has an
encoder, positions can be expressed in either motor steps or encoder counts. Set the actual position units menu to
the desired value.
The encoder to step ratio fields must be set to reflect the ratio of encoder counts to motor steps, if encoder position-
ing or stall detection is in use.
3.2.9 Step #6: Initialize Microstepper Parameters
This step of the axis setup wizard is used to select the microstepper parameters.
Set the number of phases field to match the number of electrical phases used by your microstepping
motor (usually 2).
If this motor has an encoder, input positions can be expressed in either motor steps or encoder counts.
Set the actual position units menu to the desired value.
The phase counts parameter represents the number of microsteps per electrical cycle (4 times the desired
number of microsteps). For example, a phase counts value of 256 sets the number of microsteps to 64
(256/4). The maximum number of microsteps that can be generated per full step is 256, giving a maxi-
mum phase counts value of 1024.
Set the motor command parameter to a low value between 1% and 15%, keeping in mind that the
motor may start to move at a rate proportional to the motor command setting.
