* 1. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
* 2. The factory setting will change when the control method is changed. The open-loop vector 1 factory settings are given.
* 3. E1-11 and E1-12 are disregarded when set to 0.0.
* 4. E1-13 is set to the same value as E1-05 by autotuning.
* 5. The setting range for open-loop vector 2 control is 0 to 66.0 (0 to 132.0 for PRG: 103).
Setting Inverter Input Voltage
Set the Inverter input voltage correctly in E1-01 to match the power supply voltage. This set value will be the
standard value for the protection function and similar functions.
The overvoltage detection level (OV) and the braking transistor operation level (BTR) vary depending on the
input voltage as shown in the following table.
* These are values of operation levels for braking transistors built in Inverters of 0.4 to 15 kW. Refer to FOR VARISPEED-600 SERIES INVERTER BRAK-
ING UNIT BRAKING RESISTOR UNIT INSTRUCTIONS (TOBPC720600000) for operation levels for separately-installed type Braking Resistor Units.
If selecting a fixed V/f pattern (E1-03 = 0 to E) in V/f control the values of the max. voltage (E1-05), the mid.
Output frequency voltage (E1-08), and the min. output frequency voltage (E1-10) will change if the value for
the input voltage setting (E1-01) is changed.
