TENSION SENSORLESS TORQUE CONTROL
Taper ratio setting input adjustment (Pr.829, Pr.902 to Pr.905, Pr.917,
Pr.918, Pr.926, Pr.927)
• When the taper ratio setting is input using analog input, use the following parameters to calibrate the input value of each
terminal. The taper ratios are calibrated for the 0% and 100% analog inputs. (The values for the 0% and 100% analog
inputs are fixed.)
∗1
The initial input range is 20 to 100%.
• When the taper ratio setting is input using analog input, the input value can be filtered using
Pr.829 Taper ratio setting
input filter time constant
.
Taper mode selection (Pr.1284)
• Use
Pr.1284 Taper mode selection
to select the tension reduction method (taper mode) for the taper function.
