6.1.26 Electromagnetic compatibility (EMC)
This is a summary of the EMC performance of the drive. For full details, refer to the EMC Data Sheet which can be obtained from the supplier of the
drive.
Table 6-26 Immunity compliance
1. Applies to ports where connections may exceed 30 m length. Special provisions may be required in some cases - refer to the Digitax HD M75X
EMC data sheet which can be obtained from supplier of the drive.
2. Not all parts can be tested using the IEC 61000-4-5 standard. Where cabling between external power supplies and the drives are 10 m the power
supply itself should provide sufficient surge protection.
Emission
The drive contains an in-built filter for basic emission control. An
additional optional external filter provides further reduction of emission.
The requirements of the following standards are met, depending on the
motor cable length and switching frequency.
