5.3 Description of Function Codes 5.3.8 J codes (Applied functions)
<Application examples: Dancer control> (for winders)
Example 1: When an external sensor has the output range of -7 to +7 VDC:
• Use terminal [12] as the input terminal in voltage.
• When the external sensor has ±7 VDC of bipolar output, inside the inverter ±7 VDC should be equivalent to
±100%. To convert ±7 VDC from the output of an external sensor to ±100%, the gain (C32 for analog input
adjustment) has to be set 143% (≈ 10 V / 7 V *100).
Example 2: When an external sensor has the output range of 0 to 10 VDC:
• Use terminal [12] as the input terminal in voltage.
• When the external sensor has unipolar output, inside the inverter it is controlled within the range of 0 to 100 %.
In this example, it is recommended that the dancer reference position is set around the 5 V (50 %) point.
