11.3
Earth (ground) fault detection at start
Select whether to make earth (ground) fault detection at start. When enabled, earth (ground) fault detection is performed
immediately after a start signal input to the inverter.
*1
Gr.1 and Gr.2 are the parameter initial value groups. (Refer to
• If a ground fault is detected at start while
Pr.249
= "1", the output-side earth (ground) fault overcurrent (E.GF) is displayed
and the outputs are shut off.
• When the
Pr.72 PWM frequency selection
setting is high, enable the ground fault detection at start.
NOTE
• Because the detection is performed at start, output is delayed for approx. 20 ms every start.
• Use
Pr.249
to enable/disable ground fault detection at operation start.
