30-Second Overload Capacity
The overload capacity of the L1000E is 133% for 30 seconds. Multiply the carrier de-rated output amps in
1.33 to obtain the 30 second overload capacity. Acceleration of the elevator and the counterweight to full speed
generally requires output amps above the motor's nameplate rating.
Example: L1000E model CIMR-LE2A0075 operating at 15 kHz carrier has a de-rated current of 60.0 Amps,
The 30 second overload is 133% of 60.0 Amps (80.0 Amps) for 30 seconds.
5-Second Overload Capacity
Table 2
lists the maximum 5.0 second overload current capacity of L1000E models at carrier frequencies common to
elevator applications. Most elevators will reach full speed in less than 5.0 seconds.
Prevent overload/overcurrent faults by not exceeding the 5.0 second overload capacity.
