Mitsubishi Electronics FR-S500 Output terminal function parameters, 2.4.1, Up-to-frequency Pr

Output terminal function parameters

2.3.19 Start-time ground fault detection selection (Pr. 40 )

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

Protective function will not activate if a ground fault occurs during operation.

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
	Start-time ground			0: Ground fault detection for	Setting is
40		0	0, 1	protection is not executed.
	fault detection			1: Ground fault detection for	enabled when
	selection				Pr. 30 = "1".
				protection is executed.

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.

REMARKS

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

Use Pr. 64 or Pr. 65 (output terminal function selection) to assign the terminal used for SU signal output.

CAUTION

Using Pr. 64 or Pr. 65 to change the terminal assignment may affect the other functions. Please make setting after confirming the function of each terminal. (Refer to page 100.)
