Chapter 5. FUNCTIONS

■G.SOAK (Guarantee soak)

Separate G.SOAK settings can be made in CH1 and CH2 programs.

G.SOAK on/off state, type and G.SOAK width is set by the segment. G.SOAK are of three types: segment start point, segment end point and the entire segment. G.SOAK time is set using the variable parameter PA46 setting. Any offset between SP and PV triggers a G.SOAK wait which narrows the distance between SP and PV to guarantee the segment execution time. G.SOAK operates not only on SOAK but also on RAMP segments.

Note, however, that in FAST mode a G.SOAK setting does not trigger a G.SOAK wait.

When a G.SOAK wait occurs in one channel in sync mode (variable parameter PA04 is set to 1), the program in the other channel is halted.

G.SOAK can be cleared with an external switch input. The following types of clearing conditions can be selected using setup data setting C71 to C74.

(1)G.SOAK is cleared when an external switch contact is set to on or when PV meets the G.SOAK clearing conditions.

(2)G.SOAK is cleared when an external switch contact is set to on and PV meets the G.SOAK clearing conditions.

•G.SOAK at start of segment

PV and SP are compared at the beginning of the segment. The segment starts when the absolute value of the difference continues beyond the G.SOAK time and becomes narrower than G.SOAK width.

A G.SOAK wait state continues until these conditions are met which is announced by the flashing of the linear LED on the left of the profile display. The operating condition is the same as HOLD at the beginning of a segment (time = 0).
