output This constant is automatically
set during autotuning.
* 1. The factory settings depend on the Inverter capacity. The values for a 200 V Class Inverter of 0.4 kW are given.
* 2. The setting range is 10% to 200% of the Inverter's rated output current. The value for a 200 V Class Inverter of 0.4 kW is given.
For the motor no-load current, set E2-03 to a value less than that of E2-01.
* 3. The setting range depends on the Inverter capacity. The value for a 200 V Class Inverter of 0.4 kW is given. The upper limit depends on the setting of
E2-01.
* 4. The lower limit of E2-08 is the setting value of E2-07.
Manual Motor Constant Setting Methods
The motor constants settings methods are given below. Make (enter) settings referring to the motor test report.
Motor Rated Voltage Setting
Set E2-01 to the rated current on the motor nameplate.
Motor Rated Slip Setting
Set E2-02 to the motor rated slip calculated from the number of rated rotations on the motor nameplate.
Amount of motor rated slip = Motor rated frequency (Hz) - No. of rated rotations (min
poles/120.
Motor No-Load Current Setting
Set E2-03 to the motor no-load current using the rated voltage and rated frequency. The motor no-load current
is not normally written on the motor nameplate. Consult the motor manufacturer.
Factory setting is the no-load current value for a standard Yaskawa 4-pole motor.
Number of Motor Poles Setting
E2-04 is displayed only when V/f control method with PG
number of motor poles (number of poles) as written on the motor nameplate.
Motor Line-to-Line Resistance Setting
E2-05 is set automatically when performing motor line-to-line resistance autotuning. When you cannot per-
form tuning, consult the motor manufacturer for the line-to-line resistance value. Calculate the resistance from
the line-to-line resistance value in the motor test report using the following formula, and then make the setting
accordingly.
