2 – Machine Setup
Absolute Home Angle: Defines the position of the axis when the home limit switch or marker pulse is detected.
Home Offset Angle: Allows the user to set an offset angle from the home limit switch.
Use Home Limit Switch: Tells the CNC to look for a home limit switch during phase one of the homing sequence.
Home Direction: Determines which direction the axes will travel during phase one of the homing sequence.
Use Marker Pulse: When enabled, the absolute home position will be assigned at the instant the marker pulse is
detected. It is recommended that the marker pulse be used for optimal homing repeatability.
Rotate Axis
In Phoenix, a Rotate Axis is equivalent to a C axis in the standard orientation (X is Transverse and Y is rail).
Proportional Gain: Proportional Gain correlates to Elastic Stiffness in the control loop. Increasing the proportional gain
increases the static stiffness, but decreases response of the servo loop.
Under proportional loop control, the drive system will apply a restoring torque to the motor in proportion to
the position error of the axis.
With a Proportional Gain too high, the system will be unstable which will result in overshoots and a generally
“nervous” and shaky axis. This is also referred to as a “hot” control loop.
