EXT-13: Real Speed Direction - Sub-B
It displays actual motor rotation direction regardless of
control mode selected, when Sub-B board is installed
and EXT -12 is set to Feed-back.
EXT-14: Encoder Feedback Frequency - Sub-B
It displays frequency regardless of control mode
selected, when Sub-B board is installed and EXT -12 is
set to Feed-back.
EXT-15: Pulse Input Signal Selection – Sub-B
This code sets the encoder pulse to use. [A+B] uses two
encoder signal lines of A and B, and [A] uses one
encoder signal line of A or B.
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).
