6 EMC COUNTERMEASURES AND EFFECTS
6.4 Connecting multiple servo amplifiers to one EMC filter
Selection example
The following figure shows the connection example when three MR-J5-100A are connected with one EMC filter.
Apply each data to the following calculation formula.
The calculation results are as follows.
Rated input voltage of EMC filter: 500 V
≥
Rated input voltage of servo amplifier: 3-phase 200 V AC to 240 V AC
Rated input current of EMC filter: 30 [A]
≥
Total rated input current of servo amplifier: 15 [A]
Total length of servo motor power cable [m] acceptable for the EMC filter 100 [m]
≥
Total length of servo motor power cable 60
[m]
Apply the calculation result to the following table.
