Yaskawa AC Drive Z1000 AC Drive HVAC Fan - Manual (Page 68)

• B-type insulation: Multiply 0.92 times the resistance value (Ω) listed on the test report at 75 °C.
• F-type insulation: Multiply 0.87 times the resistance value (Ω) listed on the test report at 115 °C.
Set the Motor Iron Loss for Torque Compensation
Only required when using V/f Control. Enter this value in watts to E2-10. The drive uses this setting to improve the precision
of torque compensation.
u E5: PM Motor Settings
These parameters set the motor data of a PM motor.
Perform Auto-Tuning for PM motors. The motor data can be entered manually, if known.
Note: 1. E5-oo parameters are visible only when a OLV/PM motor control mode is selected (A1-02 = 5).
2. E5-oo parameters are not reset when the drive is initialized using parameter A1-03.
n E5-02: Motor Rated Power
Sets the rated power of the motor. Determined by the value set to T2-04 during Stationary Auto-Tuning for PM motors.
No. Parameter Name Setting Range Default
E5-02 Motor Rated Power 0.10 to 370.00 kW
Determined by
o2-04
n E5-03: Motor Rated Current
Sets the motor rated current in amps. Automatically set when the value is entered to T2-06 during Auto-Tuning.
No. Parameter Name Setting Range Default
E5-03 Motor Rated Current
10 to 200% of drive rated
current
Determined by
o2-04
Note: Display is in the following units: 5A0007 to 5A0017: 0.01 A units; 5A0022 to 5A0242: 0.1 A units.
n E5-04: Number of Motor Poles
Sets the number of motor poles. Automatically set when the value is entered to T2-08 during Auto-Tuning.
No. Parameter Name Setting Range Default
E5-04 Number of Motor Poles 2 to 48
Determined by
o2-04
n E5-05: Motor Stator Resistance (r1)
Set the resistance for one motor phase. Do not enter the line-to-line resistance into E5-05 when measuring the resistance
manually.
No. Parameter Name Setting Range Default
E5-05 Motor Stator Resistance 0.000 to 65.000 Ω
Determined by
o2-04
n E5-06: Motor d-Axis Inductance (Ld)
Sets the d-Axis inductance in 0.01 mH units.
No. Parameter Name Setting Range Default
E5-06 Motor d-Axis Inductance 0.00 to 300.00 mH
Determined by
o2-04
n E5-07: Motor q-Axis Inductance (Lq)
Sets the q-Axis inductance in 0.01 mH units.
