The X114 signal is for switching the control to the dancer control or tension sensorless torque control. The signal inpu

Select the models so that "MM - BF rated current value × 1.05 < FR-A820 rated output current value".

No, it does not affect the control. When a swinging frequency is set in Pr.1074, the setting values in Pr.1077 to Pr.107

When the online auto tuning (magnetic field observer) is enabled, the monitoring accuracy is ± 10%.

Z phase is not required for the thickness method.

Positioning is available by inputting pulse trains to the terminal JOG, same as the A700 series.

The operation panel is also compatible with the IP55
