Trial Operation Procedures
If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the
instruction manual, hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because
the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotun-
ing 1. For elevators, failure to observe this caution may result in the cage falling or injury. If so, perform sta-
tionary autotuning 1 again and run the motor using the aforementioned procedure under the recommended
conditions or perform stationary autotuning 2 or rotational autotuning.
Usually the standard setting for E2-02 is 1 Hz to 3 Hz, and that for E2-03 is 30% to 65% of the rated current
for a general-purpose motor. Generally, the larger the motor capacity is, the smaller the rated slip and the ratio
of the no-load current to the rated current become. Use the data given in Factory Settings that Change with the
Inverter Capacity (o2-04) of Chapter 5 User Constants as a reference.
