00.0 – This parameter allows a skip frequency to be selected. Operation of the
400 inverter will be inhibited over the range (skip frequency – 2 Hz) to (skip
frequency + 2 Hz). If a frequency in this range is selected, the lower or
higher frequency will be selected and displayed. Note that during
ramping the frequency output will ramp continuously and not 'step'
through the skip range.
(00.0)
This parameter enables the tachometer input and selects the
tachometer calculation rate. See section 6 for further details of
tachometer applications.
000 Tachometer input disabled.
001 Normal feedback.
002 Feedback control suspended during ramping.
003 As 001, except output disabled when frequency falls to P07 (minimum
frequency).
004 As 002, except output disabled when frequency falls to P07 (minimum
frequency).
