Description
This parameter is only used if the drive is used to control the dancer
loading. If the drive is not controlling the dancer loading
DANCER LOAD REF is not sent to an AO) then this parameter can be
ignored.
If "NORMAL GAIN" is selected, stall mode is active when the line
speed is less than 62.29 STALL SPEED. When stall mode is active,
03.04 DANCER LOAD REF is reduced to a percentage of
DANCER LOAD SETPT as defined by
mode, the PI regulator uses the normal gain and integration time.
If "STALL GAIN" is selected, the reaction is the same as "NORMAL
GAIN" except that the PI regulator uses
62.31 STALL INTEG.
Stall function is not selected.
Stall function is selected and PI regulator gain at stall equals P-GAIN. 2
Stall function is selected and PI regulator gain at stall equals
STALL P-GAIN.
Setting range.
Percentage of 11.05 EXT1 REF MAXIMUM. Goes into stall mode
below this speed.
Setting range.
Proportional gain of the dancer PI regulator when in stall mode.
Setting range.
Integration time of the dancer PI regulator when in stall mode.
