5.5 E: Motor Parameters
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference 251
Doing Auto-Tuning automatically sets the E2 parameters to the optimal values. If you cannot do Auto-Tuning, set the
E2 parameters manually.
■ E2-01: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Motor Rated Current (FLA) Sets the motor rated current in amps. Determined by o2-04
(10% to 200% of the drive
rated current)
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: D002 to D046, A002 to A042, B001 to B014
–0.1 A: D059 to D273, A054 to A248, B021 to B302
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.
(Hex.)
Name Description
Default
(Range)
E2-02
(030F)
Motor Rated Slip Sets motor rated slip. Determined by o2-04
(0.000 - 20.000 Hz)
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
-1
(r/min))
• p: Number of motor poles
■ E2-03: Motor No-Load Current
No.
(Hex.)
Name Description
Default
(Range)
E2-03
(0310)
Motor No-Load Current Sets the no-load current for the motor in amps when operating at the rated frequency and the no-load
voltage.
Determined by o2-04
(0 to E2-01)
Note:
The default settings and setting ranges are in these units:
• 0.01 A: D002 to D046, A002 to A042, B001 to B014
• 0.1 A: D059 to D273, A054 to A248, B021 to B302
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)
Auto-Tuning automatically sets this parameter to the value of [Number of Motor Poles].
