Decompression

This parameter defines the acceleration time of Y-axis during decompression.

This is the nominal acceleration of the axis, used to control the axis from zero to maximum speed in the decompression phase. This parameter must be programmed as the time in which the axis accelerates from zero to maximum speed.

This parameter defines the deceleration time of Y-axis during deceleration.

This is the nominal deceleration of the axis, used to control the axis from maximum to zero speed when axis comes to its position in the deceleration phase. This parameter must be programmed as the time in which the axis decelerates from maximum to zero speed.

This parameter defines the Proportional gain factor of Y-axis during decompression phase.

This gain factor defines the response to changes in the control signal. A high gain gives a quick response, if the gain is too high it will cause oscillation.

This parameter defines the gain factor for braking of Y-axis during decompression phase.

To set gain factor for the axis when approaching the programmed position for a quick and smooth approach to target point.

This parameter defines the gain factor for reducing the lag error of Y-axis during decompression phase. Thereby the beam follow the computed cycle more accurately.

By increasing this gain, the beam will follow the computed cycle more accurately. It is recommended not to set this value too critically. A tracking error between 0.8 and 1.2 mm is a good practical value in decompression phase.

This parameter defines the delay time at the end of decompression phase.

The delay after the decompression will avoid a jump at the start of the opening phase due to elasticity in the system. During this delay the pressure is set to zero and the proportional valves are opened in the opening direction. The "end of decompression" output (MS_DOP_EndofDecomp) becomes active after this delay has elapsed.

The value of this parameter can be determined as follows:

This parameter defines the delay before opening pressure is set.

After decompression phase, the beam may show a slight 'hop' in the movement. This delay will avoid such movement of the beam.

This parameter defines the minimum decompression distance the beam should move during decompression phase.

If the programmed decompression distance is less than this parameter, then the beam is moved to this distance in the decompression phase.
