EXT-05: V2 Mode Selection – Sub-A, Sub-C
‘V2’ signal can be used as the frequency reference and
override function.
[None]
V2 signal is not used.
[Override]
‘V2’ signal override the frequency reference signal (V1, I,
V1+I) selected in DRV-04.
[Reference]
‘V2’ signal is used as the frequency reference. At this time,
the frequency reference selected in DRV-04 is ignored.
EXT-06 ~ EXT-10: Analog Voltage Input (V2)
Signal Adjustment – Sub-A, Sub-C
This is used to adjust the analog voltage input signal when
the frequency is referenced or overridden by the ‘V2’
control terminal. This function is applied when EXT-05 is
set to ‘Override’ or ‘Reference’. Reference Frequency
versus Analog Voltage Input Curve can be made by four
parameters of EXT-07 ~ EXT-10.
This is the filtering time constant for ‘V2’ signal input. If the
‘V2’ signal is affected by noise causing unstable operation
of the inverter, increase this value. Increasing this value
may make response time slower.
This is the minimum voltage of the ‘V2’ input at which the
inverter outputs minimum frequency.
This is the minimum frequency the inverter outputs when
there is the minimum voltage (EXT-07) on the ‘V2’ terminal.
This is the maximum voltage of the ‘V2’ input at which the
inverter outputs maximum frequency.
This is the maximum frequency the inverter outputs when
there is the maximum voltage (EXT-09) on the ‘V2’
terminal.
