These parameters are password protected. Some parameters are the same as on the Advanced Tab.
• Encoder pulse edges per meter - Determined by the type of encoder and the threaded shaft of the lifter.
• Full Speed - The maximum speed of the lifter. Full Speed is used above Slow Down Height.
• Home Distance - The distance of the home position from the limit switch.
• Manual Acceleration & Manual Deceleration - used on jog, when AVC is on.
• Machine Acceleration & Machine Deceleration – used when the software drives the lifter.
• Homing Speed - The speed used in the homing process.
• Out Of Limit Speed - The speed used when the torch is moving out of limit switch.
• Plate Contact Release Speed - The speed used when driving out of plate until contact is released.
• Adjust Speed - Used in arc-voltage control process to determine the maximum control speed of the lifter
• Up Limit Timeout - When moving up, the torch halts after this timeout if the limit switch is not found.
• Main Arc Lost Timeout - typically 0.1s to avoid loosing the cut without real cause.
• Hold OFF AVC Delay - Additional delay after Hold OFF which can be useful after piercing and in corners.
• Upper Soft Limit Distance – Upper soft limit which is located above the limit switch. The position of the upper soft limit is determined by
adding the Upper Soft Limit Distance to the position of the limit switch.
• Lower Soft Limit Distance – Lower soft limit which is located below the plate. The position of the lower soft limit is determined by sub
-
tracting the Lower Soft Limit Distance from the position of the limit switch. Lower soft limit is supposed to be determined so that short
motion below table surface is allowed but limiting the lifter from hitting the hard stop of the lifter.
• Reference Position Error Limit - If there is a cumulative error in the position of the limit switch, the Reference Position Error Limit deter
-
mines how large of an error can be tolerated. If the Reference Position Error Limit is exceeded, the torch performs homing
• Voltage Gain - Determines how much force the system uses to correct the difference between the actual voltage and the target voltage.
• P-gain - Used to tune the movement. Too large of a value can cause the lifter to oscillate and too small of a value makes the movement
soft and inaccurate.
• I-gain - Used to ine-tune the movement of the lifter.
• Torch collision polarity inverted – Select NC or NO use of a collision sensor.
