5.3 Description of Function Codes
5-202
<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.
PID display coefficient and Monitoring
To monitor the PID command and its feedback value, set the scale to convert the values into easy-to-understand
physical quantities such as temperature. The display unit is invalid on the standard keypad (TP-M2). The display
unit is used with the multi-function keypad (TP-A1-E2C).
Display unit Maximum scale Minimum scale
Terminal [12] C58 C59 C60
Terminal [C1] (C1) C64 C65 C66
Terminal [C1] (V2) C70 C71 C72
Refer to function codes C59, C60, C65, C66, C71 and C72 for details on scales, and to E43 for details on
monitoring.
