Note:1. Since detection is made at a start, an about 20ms output delay occurs at
every start.
2. When a ground fault is detected with "1" set in Pr. 249, alarm output "E.GF"
is detected and the output is shut off.
3. If the motor capacity is less than 0.1kW, ground fault protection may not be
provided.
