Pressure Control

In "pressure control" the pressure value of a load cell is controlled by performing pressure control with a pressure control
compatible servo amplifier (MR-J4-B-LL).
By setting the feed, dwell, and pressure release processes to devices as profiles, and turning ON the "feed/dwell startup
device", control switches to "pressure control mode" and executes pressure control.
When performing pressure control, setting pressure control data for each axis is required. Refer to the pressure control for
details on pressure control data. (Page 207 Pressure control data)
For performing "pressure control", use a pressure control compatible servo amplifier and software version.
The software versions for pressure control compatible servo amplifiers are shown in the table below.

• Pressure control is not supported when control unit is [degree]. If the control unit is set to [degree] and the
pressure control parameters are enabled, a moderate error (error code: 30F7H) occurs.
• Up to 8 axes can be controlled with pressure control. When the number of axes set for pressure control
exceeds 8 axes, a moderate error (error code: 30F7H) occurs.
• Set the "Stop function at forward/reverse side" of the servo parameter "Pressure control function selection 1
(PT12)" to "1 (Stop at forward side: Valid, stop at reverse side: Invalid)". When stop at reverse side is set to
"Valid", a minor error (error code: 19DFH) occurs.
