7-6 EMC Filter
Use EMC filters to enhance the EMC performance for the environment and machines and to comply with
EMC regulations, further reducing EMC problems. If you purchase a motor drive without a built-in EMC
filter, it is recommended that you select the EMC filters as shown below. For some motor drive models,
you need to work with zero phase reactors to be compliant with EMC regulations. Refer to the table and
figure below for the recommended model, setting method, and maximum motor cable length of the EMC
filter and zero phase reactor.
NOTE 1: It is not necessary to add a zero phase reactor for passing the C2 conducted emission test.
The maximum motor cable length of the conducted emission C2 class for VFD1A7MS53ANSAA, VFD3A0MS53ANSAA and
VFD4A2MS53ANSAA is 75 m, others are 100 m.
