No. Turn OFF and ON both main circuit and control circuit.

No alarm occurs due to the abnormal temperature. In the main circuit, alarms such as heatsink overheat will be occurred.

Yes, the current response is also improved at the same rate.

The FR-A800 has metal installation holes regardless of the capacity.

A tension sensor such as a dancer roll is required for speed control. Because an actual line speed input is required for

UVT will occur when reactor is not connected. Always connect a reactor that matches the motor capacity.

Since the lower limit has been internally set, the setting value of 3 % or less is recognized as 3%.

Z phase is not required for the thickness method.

The operation panel is also compatible with the IP55

Yes, the resistance values are the same.
