Once all electrical connections have been completed, the system can be calibrated. Axis calibration can be completed using the following steps:

Motor: Distance per Revolution

First, note the pitch of your ball screw. The pitch defines how much the ball nut moves when the ball screw completes one full rotation.

In the F1 Setup screen, open the axis setup window and enter the ball screw pitch in the Motor: Distance per Revolution field.

If the machine uses timing belts or a rack and pinion system, enter the amount of axis movement that occurs when the motor shaft completes one full rotation.

If this value is unknown or difficult to calculate, the calibration wizard can be used, as explained at the bottom of this page.

Drive: Pulses per Revolution

Servo and stepper motor drives use switches or software tools to set the Pulses Per Revolution (PPR).

These settings define how many pulses are required for the motor shaft to complete one full rotation.

Maximum Feed Rate

Each machine axis has a maximum allowable speed based on hardware and safety limitations.

The maximum feed rate value ensures that the system does not exceed this limit during operation.

This value may vary for each axis depending on the machine design.

Acceleration

The acceleration value for each axis can be set based on the moving mass and available motor torque.

Axis Direction

The Invert Direction option is used to reverse the direction of axis travel.

It is important to ensure that the axis is moving in the correct direction before setting minimum and maximum travel limits or using the calibration wizard.

Minimum and Maximum Travel

These values define the usable travel range of the axis.

In most setups, this range is between 0.00 and a positive value. However, in some cases, such as the Z axis of a milling machine, the value may be negative because the axis homes at 0.00 and moves in the negative direction toward the machine bed.

NOTE:

The minimum and maximum travel values also define the soft limits of the axis. It is important to set these values accurately.

During initial setup, set large temporary values to avoid hitting limits. For example:

• Minimum travel: -10000
• Maximum travel: 10000

Final travel values should only be set after homing is configured or after tool changer setup is complete.

Axis Calibration Wizard

If the Distance per Revolution value is unknown or difficult to calculate, the Axis Calibration Wizard can be used.
