5.5 E: Motor Parameters
No. Parameter Name
E4-02 Motor 2 Rated Slip
E4-03: Motor 2 Rated No-Load Current
n
Sets the magnetizing current of motor 2 as a percentage of the full load current. This value is automatically set during Rotational Auto-Tuning. If Auto-
Tuning cannot be performed, contact the motor manufacturer for this information so that it can be entered manually.
No. Parameter Name
E4-03 Motor 2 Rated No-Load Current
Note: Set the lower and higher digits to the value corresponds to the capacity of the drive: 11 kW or less: Sets the lower 2 digits, 11 kW or higher: Set to the lowest digit
E4-04: Motor 2 Motor Poles
n
Sets the number of motor poles for motor 2. This value should be entered during the Auto-Tuning process, after which this parameter will be automatically
set.
No.
E4-04
E4-05: Motor 2 Line-to-Line Resistance
n
Sets the phase-to-phase resistance of motor 2 in ohms. This value is automatically set when Auto-Tuning is executed.
No.
E4-05 Motor 2 Line-to-Line Resistance
Note: The setting range is 0.00 to 130.00 when using a drive capacity of 0.2 kW or less.
E4-05 is the only parameter that is automatically set when Stationary Auto-Tuning is performed (also called, "Auto-Tuning for resistance between lines").
If Auto-Tuning is not possible for some reason, contact the motor manufacturer to find out what the line-to-line resistance is for the motor, then calculate
this E4-05 using the appropriate formula below.
• E-type insulation: Multiply 0.92 times the resistance value (W) listed on the Test Report at 75°C.
• B-type insulation: Multiply 0.92 times the resistance value (W) listed on the Test Report at 75°C.
• E-type insulation: Multiply 0.87 times the resistance value (W) listed on the Test Report at 115°C.
E4-06: Motor 2 Leakage Inductance
n
Sets the voltage drop due to motor leakage inductance as a percentage of rated voltage of motor 2. This value is automatically set during Auto-Tuning.
No.
E4-06 Motor 2 Leakage Inductance
E4-07: Motor 2 Motor Iron-Core Saturation Coefficient 1
n
Set to the motor iron saturation coefficient at 50% of magnetic flux. This value is automatically set during Rotational Auto-Tuning.
No.
E4-07
E4-08: Motor 2 Motor Iron-Core Saturation Coefficient 2
n
Set to the motor iron saturation coefficient at 75% of magnetic flux. This value is automatically set during Rotational Auto-Tuning.
No.
E4-08 Motor 2 Motor Iron-Core Saturation Coefficient 2
E4-09: Motor 2 Mechanical Loss
n
Sets the motor mechanical loss as a percentage of motor rated power (kW).
No.
E4-09
This parameter seldom needs to be changed, but may need to be adjusted in the following circumstances:
• When there is a large amount of torque loss due to motor bearing friction.
• When there is a large amount of torque loss in a fan or pump application.
E4-10: Motor 2 Iron Loss
n
Sets the motor iron loss in watts for motor 2.
No.
E4-10
E4-11: Motor 2 Rated Capacity
n
Sets the motor rated capacity in units of 0.01 kW. This value is automatically set when Auto-Tuning is performed.
