2.3.19 Start-time ground fault detection selection

You can choose whether to make ground fault detection valid or invalid at a start. Ground fault detection is executed only right after the start signal is input to the inverter.

CAUTION

1.If a ground fault is detected with "1" set in Pr. 40, alarm output "" is detected and the output is shut off.

2.If the motor capacity is less than 0.1kW, ground fault protection may not be provided.

REMARK

When a ground fault is detected with "1" set in Pr. 40, an approximate 20ms delay occurs at every start.

2.4 Output Terminal Function Parameters

2.4.1 Up-to-frequency sensitivity

The ON range of the up-to- frequency signal (SU) output when the output frequency reaches the running frequency can be adjusted between 0 and ±100% of the running frequency. This parameter can be used to ensure that the running frequency has been reached to provide the operation start signal etc. for related equipment.

REMARKS

Using Pr. 64 or Pr. 65 to change terminal assignment may affect the other functions. Make setting after confirming the function of each terminal. (Refer to page 90.)
