2.5 E: Motor Parameters
YASKAWA ELECTRIC TOEP C710687 03B FSDrive-MV1000 Parameter Guide 161
u E4: Motor 2 Parameters
E4 parameters contain the motor data for motor 2. These parameters are usually set automatically during the
Auto-Tuning process (Rotational Auto-Tuning, Stationary Auto-Tuning). If Auto-Tuning cannot be performed, refer to
the FSDrive-MV1000 Instructions (Manual No. TOEP C710687 02).
n
E4-01: Motor 2 Rated Current
Set E4-01 to the full load amps (FLA) stamped on the nameplate of motor 2. This value is used for motor protection and
to calculate torque limits. If Auto-Tuning completes successfully, the value entered in T1-04 will automatically be saved
to E4-01.
Note: If the motor rated current in E4-01 is set lower than the motor no-load current in E4-03, then a parameter setting error will occur
(oPE02). E4-03 must be set correctly to prevent this error.
n E4-02: Motor 2 Rated Slip
This parameter sets the motor 2 rated slip frequency. Slip compensation is based on this value. The drive calculates this
value automatically during Auto-Tuning (Rotational Auto-Tuning and Stationary Auto-Tuning).
For information on calculating the motor rated slip, refer to E2-02: Motor Rated Slip on page 157.
n
E4-03: Motor 2 Rated No-Load Current
Set the no-load current for motor 2 in amperes when operating at the rated frequency and the no-load voltage. The drive
sets E2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning). The motor no-load
current listed in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a
copy of the motor test report.
n
E4-04: Motor 2 Motor Poles
Set the pole number of motor 2 to E4-04. If Auto-Tuning completes successfully, the entered value in T1-06 will be
automatically saved in E4-04.
n
E4-05: Motor 2 Line-to-Line Resistance
Sets the line-to-line resistance for the motor 2 stator winding. If Auto-Tuning completes successfully, this value is
automatically calculated. Enter this value as line-to-line and not for each motor phase. Refer to E2-05: Motor
Line-to-Line Resistance on page 158 to manually enter this parameter setting.
