18 DBP - Rev 6/93 4.2.1 Current feedback, Current feedback multiplier (CFM) and Current loop Three current feedbacks are obtained by measuring the voltage drop across current sensing resistors or by current transformers (when using the isolation option). These three signals are synthesized and multi...

19 DBP - Rev 6/93 This function should be activated whenever the rated current AND the peak current of the motor are less than 20% of the amplifier rated continuous and peak limits respectively. Sometimes, oscillations may occur in the current loop due to the fact that the feedback gain was multipli...

20 DBP - Rev 6/93 Ip - Iop Tp = 2.2ln ---------- Ip - Ic Iop - Actual operating current before the peak demand. The result of this filter is that the maximum peak can last for a maximum of 2 seconds.
