17. APPLICATION OF FUNCTIONS
3) When the gain switching time constant is disabled
a) Gain switching time constant disabled was selected.
The gain switching time constant is disabled with this setting. 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
Switching at [Pr. PB28 (CDT)] = 100 [ms] only when gain switching off (when returning)
b) Gain return time constant disabled was selected.
The gain switching time constant is enabled with this setting. 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].
