E2: Motor Parameters - YASKAWA HV600 Manual

Note:
• After Auto-Tuning, the value of E1-13 = E1-05 [Maximum Output Voltage].
• When E1-13 = 0.0, use the value of E1-05 to control the voltage.

E2: Motor Parameters

E2 parameters [Motor Parameters] set induction motor data. To switch drive operation from one motor to another
motor, configure the first motor (motor 1).
Doing Auto-Tuning automatically sets the E2 parameters to the optimal values. If you cannot do Auto-Tuning, set the
E2 parameters manually.
Note:
If you set A1-02 [Control Method Selection] to these control methods, the keypad will not show E2-xx:
• 5 [PM Open Loop Vector]
• 8 [EZ Vector Control]
■
E2-01: Motor Rated Current (FLA)
No.
Name
(Hex.)
E2-01 Motor Rated Current (FLA)
(030E)
Note:
• If E2-01 < E2-03 [Motor No-Load Current] the drive will detect oPE02 [Parameter Range Setting Error].
• The default settings and setting ranges are in these units:
–0.01 A: 2011 to 2046, 4005 to 4014
–0.1 A: 2059 to 2273, 4021 to 4302
The value set for E2-01 becomes the reference value for motor protection and the torque limit. Enter the motor rated
current as written on the motor nameplate. The value of E2-01 is automatically set to the value input for "Motor Rated
Current" by the Auto-Tuning process.
■
E2-02: Motor Rated Slip
No.
Name
(Hex.)
E2-02 Motor Rated Slip
(030F)
This parameter value becomes the base slip compensation value. The drive automatically sets this parameter during
Auto-Tuning. When you cannot do Auto-Tuning, calculate the motor rated slip with the information on the motor
nameplate and this formula:
E2-02 = f - (n × p) / 120
• f: Motor rated frequency (Hz)
• n: Rated motor speed (min
• p: Number of motor poles
■
E2-03: Motor No-Load Current
No.
Name
(Hex.)
E2-03 Motor No-Load Current
(0310)
Note:
The default settings and setting ranges are in these units:
• 0.01 A: 2011 to 2046, 4005 to 4014
• 0.1 A: 2059 to 2273, 4021 to 4302
