Dancer feedback speed control details
Dancer signal input selection (Pr.363)
• Use Pr.363 Dancer / tension sensor feedback input selection to select the input terminal for the dancer signal
(measured value).
Pr.363 setting
3 Terminal 2 (0 to 100%) (0 to 5 V)
4 Terminal 4 (20 to 100%) (4 to 20 mA)
5 (initial value) Terminal 1 (-100 to 100%) (-10 to 10 V)
6 Terminal 6 (FR-A8AZ) (-100 to 100%) (-10 to 10 V)
Dancer signal calibration example
• The following parameters are used for calibrating the dancer signal according to the input terminal. The dancer signal
analog input values at both 0% and 100% can be calibrated.

Terminal 1 (-100 to 100%)
Terminal 6 (FR-A8AZ) (-100 to 100%)
∗1 The initial input range is 20 to 100%.
• In the following example, a potentiometer with the output range of -10 to 10 V is used for inputting the dancer signal to
terminal 1 (input range: -10 to 10 V). The neutral position is defined as 0% for the calibration. C13 (Pr.917) Terminal 1 bias
(speed) and C15 (Pr.918) Terminal 1 gain (speed) are used for calibration.
• In the following example, a potentiometer with the output range of 1 to 7 V is used for inputting the dancer signal to terminal
2 (input range: 0 to 10 V). The neutral position is defined as 0% for the calibration. C3 (Pr.902) Terminal 2 frequency
setting bias and C4 (Pr.903) Terminal 2 frequency setting gain are used for calibration.
