2.5 E: Motor Parameters
YASKAWA ELECTRIC TOEP C710687 03B FSDrive-MV1000 Parameter Guide 157
u E2: Motor 1 Parameters
These parameters contain the motor data needed for motor 1. They are set automatically when Auto-Tuning is performed
(this includes Rotational Auto-Tuning, Stationary Auto-Tuning). If Auto-Tuning cannot be performed, refer to the
FSDrive-MV1000 Instructions (Manual No. TOEP C710687 02).
n
E2-01: Motor Rated Current
Set E2-01 to the full load amps (FLA) stamped on the motor nameplate. This value is used for motor protection and to
calculate torque limits. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to
E2-01.
Note: If the motor rated current in E2-01 is set lower than the motor no-load current in E2-03, than a parameter setting error will occur
(oPE02). E2-03 must be set correctly to prevent this error.
n E2-02: Motor Rated Slip
Sets the motor rated slip in Hz to provide motor control, protect the motor and calculate torque limits. This value is
automatically set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning).
If Auto-Tuning cannot be performed, calculate the motor rated slip using the information written on the motor nameplate
and the formula below:
E2-02 = f - (n × p)/120
f: rated frequency (Hz), n: rated motor speed (r/min), p: number of motor poles
n
E2-03: Motor No-Load Current
Sets the no-load current for the motor in amperes when operating at the rated frequency and the no-load voltage. This
value is automatically set during Auto-Tuning (Rotational, Stationary). The motor no-load current listed in the motor test
report can also be directly entered manually. Contact the motor manufacturer to receive a copy of the motor test report.
n
E2-04: Number of Motor Poles
Set the number of motor poles. If Auto-Tuning completes successfully, the value entered to T1-06 will automatically be
saved in E2-04.
