For example, the resolution of a 4X – 1000 line encoder counts both edges (lines) of channel A and channel
B to equal 4 counts per line time multiplied by the 1000 lines per revolution would equal 4000 counts per
revolution.
Encoder Counts/Rev = 4 Counts/Line x 1000 Lines/Rev = 4000
Encoder Polarity: This parameter allows changing of the encoder input polarity to establish proper counting for positive
machine motion without any wiring changes.
DAC Polarity: This parameter allows changing of the analog output polarity to establish proper control loop feedback
without any wiring changes.
Drive Type: This parameter is used to tell the CNC what type of control loop to run.
If you are running an external velocity loop drive (indicated by having an integrated tachometer in the motor),
select Velocity. If you are running in torque mode (no tachometer), select Current.
Current Limit: If you selected Current for Drive Type, set the maximum current output for operation of the lifter motor.
Encoder Decode Mode: Currently the CNC only supports 4X encoder decode mode. This has been done to increase
positional accuracy.
Use Hardware Overtravels: Select whether the cutting system will be using hardware overtravel switches. If Hardware
overtravel switches are used, the CNC will disable feedback and display an error message if the inputs
become active. It is recommended that hardware overtravel switches be installed.
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.
Homing with Overtravel Switch: Activates the Home feature and uses the Overtravel Switch as its reference.
The Home feature is used to set a known absolute physical position location for the tilt axis.
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.
Use Software Travel Limits: The CNC is capable of running with software overtravel limits that are based on position.
When enabled, this feature allows you to select Fault or Fast Decel when active. Fault operates as hardware
switches with immediate fault. Fast Decel uses the fast decel value to ramp down motion.
Maximum Travel Limit: If Software Overtravels are enabled, the user is prompted for the maximum travel of the cutting
machine.
Minimum Travel Limit: If Software Overtravels are enabled, the user is prompted for the minimum travel of the cutting
machine.
