Outline of pressure control

Pressure control
Pressure control for feed/dwell is available.
The load cell pressure can be monitored with the optional data monitor function. (The load cell pressure is used for feedback
for pressure control in the servo amplifier)
Change speed switching point
In the feed operation, the setting of switching points that are before the current value are skipped.

Current value
Stop at speed zero setting
When in feed/dwell operation and a switching point is set to speed 0, a deceleration stop from that point is made.
Ex.
When "V4=0", a deceleration stop from S4 is made.

Precautions for when backlash compensation is conducted on a pressure control axis
Determining rotation direction at the command level is difficult. Therefore the real current value and the feed current value at
the time of changing to position control mode may be displaced by the maximum backlash compensation amount.
(Displacement does not accumulate)
