Setting Motor parameters
Normally the motor parameters are set automatically using autotuning. If autotuning does not complete nor-
mally, set them manually.
Related parameters
Note The factory-set parameters are for a OMRON standard 4-pole motor.
* 1. The factory settings depend on Inverter capacity (the values shown are for a 200 V Class Inverter for 0.4 kW).
* 2. The setting range is 10% to 200% of the Inverter rated output current (the values shown are for a 200 V Class Inverter for 0.4 kW).
Manual Motor Parameter Setting Methods
The motor parameters settings methods are given below. To enter settings refer to the motor test report.
Motor Rated Voltage Setting
Set E2-01 to the rated current 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.
•
E-type insulation: [Line-to line resistance (W) at 75°C of test report] x 0.92 (W)
•
B-type insulation: [Line-to line resistance (W) at 75°C of test repor]t x 0.92 (W)
•
F-type insulation: [Line-to line resistance (W) at 115°C of test report] x 0.87 (W)
