Parameter Setting
• Set the parameter when you carry out optimum tuning by using gain
switching function.
For conditions of switching of the 1st and 2nd gains, refer to “Gain
Switching Function” on Page 138 of Adjustment edition.
• The parameter is used to select conditions of switching the 1st and
2nd gain in the position control mode.
• The parameter is enabled when Pr31 is 3 or 5 to 10, and sets delay
time from when it no longer meets the condition of switching
selected with Pr31 till actual return to the 1st gain.
• The parameter is enabled when Pr31 is 3, 5, 6, 9, or 10, and sets
judgment level of when the 1st and 2nd are switched.
Unit may vary depending on setting of Pr31.
• The parameter sets margin of hysteresis to be provided above and
below the judgment level set with Pr33 mentioned above.
• The following figure illustrates definitions of Pr32 (delay), Pr33
(level) and Pr34 (hysteresis).
Settings of Pr33 (level) and Pr34 (hysteresis) are valid as absolute
value (positive/negative).
