LM - Motor Data Parameters
The rated motor current in amperes, according to nameplate.
The rated motor frequency in Hz, according to nameplate.
FOR PM SYNCHRONOUS MOTORS, the relationship between the rated
motor speed, rated motor frequency and the number of motor poles
MUST NOT include any slip. For a given number of motor poles, the
rated motor speed or frequency should be verified against the nameplate
values and changed accordingly in the drive, as rounding may occur on
the nameplate. Refer to parameter LM02 Motor Speed for details.
Rated motor voltage, according to nameplate.
For induction motors, enter the rated motor voltage according to nameplate.
For PM motors, enter the no load phase-to-phase back EMF rms voltage
at rated speed. This particular unit for voltage is not typically listed on the
nameplate. As a starting point, the nameplate voltage can be entered.
This value can be determined by performing a motor tune, described further
under LL01 Motor Tune or Section 5.9 Motor Learn. As mentioned above, the
learned value may differ from the nameplate value, due to units; the learned
value will typically be lower than what is listed on the motor nameplate. After
a Motor Tune has been performed, there should be no reason to change the
learned value.
