Operating Instructions
Aspen’s Universal Low Noise Sinusoidal BLDC Drive can be operated in 2 distinct modes. This allows it the
ability to seamlessly replace all existing Aspen drives, as well as offer significant compressor noise
reduction, lower compressor operational speeds and several different input types for speed control. It also
has the ability to operate any compressor in the Aspen Compressor line.
Drive Mode Jumper Configuration –
Mode 1 operation is a direct replacement for the 1501017, 1501018, 1501029, & 1501031 High
Performance BLDC drive originally used on all A and Q series compressors. In this mode the drive will
behave as a direct replacement for the 1501017/1501018/1501029/1501031 High Performance BLDC drive.
To operate in this mode, install a jumper as shown in the picture below. While this mode replicates the
performance of the drives listed above, it does not offer the additional low noise, lower operating speeds
and additional speed input types that are available when operating in Mode 2. However, there is a
provision within this mode to operate taking advantage of the quiet sinusoidal mode only, without the
other added functions of operating in Mode 2. See Note 1 on page 9 for information regarding this.
