Chapter 6 - Parameter Description [EXT]EXT-13: Real Speed Direction - Sub-BEXT► RealSpdDir13 RXIt displays actual motor rotation direction regardless ofcontrol mode selected, when Sub-B board is installedand EXT-12 is set to Feed-back.EXT-14: Encoder Feedback Frequency - Sub-BIt displays frequency regardless of control modeselected, when Sub-B board is installed and EXT-12 isset to Feed-back.EXT-15: Pulse Input Signal Selection – Sub-BEXT► F pulse set15 A + BThis code sets the encoder pulse to use. [A+B] uses twoencoder signal lines of A and B, and [A] uses oneencoder signal line of A or B.13Factory Default: Reverse 0EXT► ENC FeedBac14 0.00 HzFactory Default:1415Factory Default: A + B 0EXT-16: Encoder Pulse Number – Sub-B00.00N/A0This is the filtering time constant of pulse input signal.This is used to make the inverter respond slowly to thepulse input signal when the EXT-14 is set to ‘Reference’.EXT-18 ~ EXT-21: Pulse Input Signal Adjustment– Sub-BThis is used to adjust the pulse input signal when thepulse input through Sub-B board references thefrequency. This function is applied when EXT-14 is set to‘Reference’. Reference Frequency versus AnalogVoltage Input Curve can be made by four parameters ofEXT-18 ~ EXT-21.EXT► F pulse x118 0.0 kHz 180.0Factory Default: 0.0 kHz 0.0This is the minimum pulse frequency at which theinverter outputs minimum frequency.EXT► F freq y119 0.00 Hz 190.00Factory Default: 0.00 Hz 0.00This is the minimum frequency the inverter outputs whenthere is the minimum pulse frequency (EXT-18).EXT► F pulse x220 10.0 kHz2010.0Factory Default: 10.0 kHz 10.0EXT► F pulse num16 1024161024This is the maximum pulse frequency at which theinverter outputs maximum frequency.Factory Default: 1024 1024This code sets the encoder pulse per rotation of encoder.EXT► F freq y221 60.00 Hz2160.00EXT-17: Filtering Time Constant for Pulse InputSignal – Sub-BEXT► F filter17 10 ms1710Factory Default: 60.00 Hz 60.00This is the maximum frequency the inverter outputswhen there is the maximum pulse frequency (EXT-20).Factory Default: 10 ms 10139
