4. Store within a relative humidity range of 0% to 90% and non-condensing environment.
Please use an air conditioner and/or exsiccator when the brushless DC motor drive will
not be used for a long time.
5.14 Affecting Other Machines
A brushless DC motor drive may affect the operation of other machines due to many reasons. Some
solutions are:
High Harmonics at Power Side
High harmonics at power side during running can be improved by:
1. Separate the power system: use a transformer for the brushless DC motor drive.
2. Use a reactor at the power input terminal of the brushless DC motor drive.
3. If phase lead capacitors are used (never on the brushless DC motor drive output!!), use
serial reactors to prevent damage to the capacitors damage from high harmonics.
