2 Product description
2.1 General information about Copeland Scroll
™ compressors
These application guidelines deal with the YBVH* variable speed horizontal Copeland scroll
compressors using R290.
These compressors have a speed range of 1500 to 5500 revolutions per
minute, corresponding to 25 up to 92 Hz. They are intended for use in refrigeration applications. They
feature a three-phase brushless permanent magnet (BPM) motor which is controlled by a motor
control drive (for example Emerson drive ED3), either single-phase or three-phase, referred to as
the "ED3 drive" throughout these guidelines.
NOTE: For more information on the motor control drive refer to the Emerson User Manual for
ED3.
2.2 Matched-pairs of compressor and drive
The matched-pairs of compressor and drive released by Emerson are listed in Table 1 below:

Table 1: Matched pairs ED3 with YBVH*
The YBVH* compressors have been qualified for use with the ED3 motor control drive, and the
matched pairs have been designed for maximum efficiency and reliability. The drive will power the
compressor, control the compressor running speed, provide compressor and drive protection and
communicate with the master controller in ModBus RTU protocol. The drive requires cooling and is
typically installed in the unit near the compressor. To optimize drive efficiency and to limit
electromagnetic interferences, external chokes must be connected to the single-phase and three-
phase drives.
YBVH* compressors with motor code "E9" are offered in matched pairs with the ED3 drive, designed
in accordance with EN 60335-1, as listed in
Table 2 . The motor protection is implemented in the ED3
drive.

It is important to ensure correct wiring at both the compressor and drive connections prior to
starting the compressor to avoid a miswire or powered reverse situation. Both situations could
potentially cause compressor damage.
NOTE: Operate Emerson matched pairs of inverter and compressor only. Other combinations
could cause problems, such as starting issues, low capacity operation or other unusual
errors.
