EXT-13: Real Speed Direction - Sub-B

EXT? RealSpdDir
13 RX
Factory Default:
Reverse
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

EXT? ENC FeedBac
14 0.00 Hz
Factory Default:
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
EXT? F pulse set
15 A + B
Factory Default:
A + 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
EXT? F pulse num
16 1024
Factory Default:
1024
This code sets the encoder pulse per rotation of encoder.
EXT-17: Filtering Time Constant for Pulse Input
Signal – Sub-B
EXT? F filter
17 10 ms
Factory Default:
10 ms

Chapter 6 - Parameter Description [EXT]
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.
EXT? F pulse x1
18 0.0 kHz
Factory Default:
0.0 kHz
This is the minimum pulse frequency at which the
inverter outputs minimum frequency.
EXT? F freq y1
19 0.00 Hz
Factory Default:
0.00 Hz
This is the minimum frequency the inverter outputs when
there is the minimum pulse frequency (EXT -18).
EXT? F pulse x2
20 10.0 kHz
Factory Default:
10.0 kHz
This is the maximum pulse frequency at which the
inverter outputs maximum frequency.
EXT? F freq y2
21 60.00 Hz
Factory Default:
60.00 Hz
This is the maximum frequency the inverter outputs
when there is the maximum pulse frequency (EXT -20).
