*1 Setting range and initial setting differ depending on inverter capacity.
*2 Set value for 200V class. For 400V class, the value is twice as that of 200V class.
*3 When using a braking resistor unit, set L3-01 to “0.”
*4 When using a mounting-type braking resistor unit (model ERF), set L8-01 to “1.”
*5 Not initialized.
*6 The display is applicable for software No. 1033 or later (FLASH side). To check which
version is being used, refer to U1-14.
