1 Selecting an L1000E AC Drive for Elevator Applications


Purpose and Intended Audience

This document contains supplementary information to aid in selection and adjustment of the L1000E Series AC drive
with these application criteria:
• Application: Conventional gear-driven, traction drive elevator applications (counterweighted)
• Motor type: 50 Hz or 60 Hz induction motors
• Near full speed, normal acceleration rates
Please refer to the L1000E Technical Manual SIEPYAIL1E01 for complete information and instructions.


Overview
This document guides the user in selecting the optimum L1000E model for elevator applications while considering these
specific needs;
• motor acceleration current
• motor audible noise
• overload capability and
• low speed operation.

What is Carrier Frequency?
Carrier frequency in PWM (pulse width modulation)-based VFD's, is the rate at which output transistors are gated,
usually 2 to 15 kHz. Higher carrier frequencies yield a better current waveform, less audible motor noise, but more VFD
thermal losses. Lower carrier frequencies yield a less optimum current waveform, increased audible noise, but less VFD
losses. Audible motor noise in applications where the motor must operate quietly can be a concern with lower carrier
frequencies.
