2.6 E: Motor Parameters
254 YASKAWA TOEPYAIHV6002A HV600 Drive Programming
The drive automatically sets this parameter during Auto-Tuning. When you cannot do Auto-Tuning, you can also use
the motor no-load current on the motor test report to enter this value manually. Contact the motor manufacturer to
receive a copy of the motor test report.
Note:
The default setting of the no-load current is for operation with a 4-pole motor recommended by Yaskawa.
■
E2-04: Motor Pole Count
No.
(Hex.)
Name Description
Default
(Range)
E2-04
(0311)
Motor Pole Count
Sets the number of motor poles.
4
(2 - 120)
Note:
When A1-02 = 0 [Control Method Selection = V/f] , the maximum value is 120.
Auto-Tuning automatically sets this parameter to the value of [Number of Motor Poles].
■
E2-05: Motor Line-to-Line Resistance
No.
(Hex.)
Name Description
Default
(Range)
E2-05
(0312)
Motor Line-to-Line
Resistance
Sets the line-to-line resistance for the motor stator windings.
Determined by o2-04
(0.000 - 65.000 Ω)
Note:
This value is the motor line-to-line resistance. Do not set this parameter with the resistance per phase.
Auto-Tuning automatically sets this parameter. If you cannot do Auto-Tuning, use the test report from the motor
manufacturer to configure the settings. You can calculate the motor line-to-line resistance with one of these formulas:
•
E-type insulation: [the resistance value (Ω) shown on the test report at 75 °C] × 0.92
•
B-type insulation: [the resistance value (Ω) shown on the test report at 75 °C] × 0.92
•
F-type insulation: [the resistance value (Ω) shown on the test report at 115 °C] × 0.87
■
E2-06: Motor Leakage Inductance
No.
(Hex.)
Name Description
Default
(Range)
E2-06
(0313)
Motor Leakage Inductance
Sets the voltage drop from motor leakage inductance when the motor is operating at the rated
frequency and rated current. This value is a percentage of Motor Rated Voltage.
Determined by o2-04
(0.0 - 60.0%)
The drive automatically sets this parameter during Auto-Tuning.
Note:
The motor nameplate does not usually show the quantity of voltage drop. If you do not know the value of the motor leakage inductance,
contact the motor manufacturer to receive a copy of the motor test report.
■
E2-10: Motor Iron Loss
No.
(Hex.)
Name Description
Default
(Range)
E2-10
(0317)
Motor Iron Loss
Sets the motor iron loss.
Determined by o2-04
(0 - 65535 W)
■
E2-11: Motor Rated Power
No.
(Hex.)
Name Description
Default
(Range)
E2-11
(0318)
Motor Rated Power
Sets the motor rated output in the units from o1-58 [Motor Power Unit Selection] .
Determined by o2-04
(0.00 - 650.00 HP)
The drive automatically sets this parameter to the value input for “ Motor Rated Power ” during Auto-Tuning.
