Pressure Control Selection; Feed/Dwell Startup Device; Dwell Forced Switching Device; Pressure Release Startup Device - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Pressure control selection

Set whether to use pressure control, or not use pressure control. Pressure control data for up to 8 axes can be set.
When pressure control selection is enabled on an axis on a SSCNET line or the number of axes set to pressure control
selection enabled exceeds eight, a moderate error (error code: 30F7H) occurs.
Pressure control selection
0: Do not use pressure control
1: Use pressure control

Feed/dwell startup device

Set the device to start feed/dwell operation.
When the feed/dwell start device turns OFF to ON, control switches to pressure control, and drives the system with the feed/
dwell operation.
When the feed/dwell startup device turns ON to OFF, the mode is reset, and switches from pressure control to positioning
control.

Dwell forced switching device

Set the device to force the switch to dwell operation during feed operation.
Operation switches to dwell operation automatically by specifying a feed/dwell switching mode in the pressure profile.
However, by turning the force switch to dwell device OFF to ON, switch to dwell operation can be made even when conditions
for switching to dwell operation are not satisfied.

Pressure release startup device

Set the device to start pressure release operation.
When the pressure release startup device turns OFF to ON, control switches to pressure control, and drives the system with
the pressure release operation. When load cell pressure drops below the set pressure, or when the pressure release startup
device turns ON to OFF, the mode is reset, and control switches from pressure control to positioning control.

Pressure command reference

Set the reference for the time constant of the pressure command.
The time constant of the pressure command is the time taken to reach the pressure command reference.

Speed limit reference

Set the reference for the time constant of the speed limit.
The time constant of the speed limit is the time taken to reach the speed limit from 0.

Abnormal pressure switching mode

Set whether to switch to dwell mode or not when the pressure reaches the value set as abnormal pressure setting during feed
operation.
If "1: Select" is set, operation is forcibly switched from feed mode to dwell mode when the time in an abnormal state exceeds
the time that was set to abnormal pressure.
Abnormal pressure switching mode
0: Unselect
1: Select

Abnormal pressure setting

Set the abnormal pressure value.
