Chapter 6 - Parameter Description [EXT]
6-56
EXT-16: Encoder Pulse Number – Sub-B
This code sets the encoder pulse per rotation of encoder.
EXT-17: Filtering Time Constant for Pulse Input
Signal – Sub-B
This is the filtering time constant of pulse input signal. This
is used to make the inverter respond slowly to the pulse
input signal when the EXT-14 is set to ‘Reference’.
EXT-18 ~ EXT-21: Pulse Input Signal Adjustment –
Sub-B
This is used to adjust the pulse input signal when the pulse
input through Sub-B board references the frequency. This
function is applied when EXT-14 is set to ‘Reference’.
Reference Frequency versus Analog Voltage Input Curve
can be made by four parameters of EXT-18 ~ EXT-21.
This is the minimum pulse frequency at which the inverter
outputs minimum frequency.
This is the minimum frequency the inverter outputs when
there is the minimum pulse frequency (EXT-18).
This is the maximum pulse frequency at which the inverter
outputs maximum frequency.
This is the maximum frequency the inverter outputs when
there is the maximum pulse frequency (EXT-20).
[Reference Frequency vs. Pulse Input]
EXT-22 ~ EXT-23: Gains for ‘Sub-B’ Board
This is the proportional gain when the EXT-14 is set to
‘Feed-back’.
This is the integral gain when the EXT-14 is set to ‘Feed-
back’.
