7. SPECIAL ADJUSTMENT FUNCTIONS
(3) When the gain switching time constant is disabled
(a) Switching time constant disabled was selected.
The gain switching time constant is disabled. The time constant is enabled at gain return.
The following example shows for [Pr. PB26 (CDP)] = 0103, [Pr. PB27 (CDL)] = 100 [pulse], and [Pr.
PB28 (CDT)] = 100 [ms].
Droop pulses [pulse]
Gain switching
(b) Return time constant disabled was selected.
The gain switching time constant is enabled. The time constant is disabled at gain return.
The following example shows for [Pr. PB26 (CDP)] = 0201, [Pr. PB27 (CDL)] = 0, and [Pr. PB28
(CDT)] = 100 [ms].
