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).
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.
∗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.
