Apply each data to the following calculation formula.
Page 33 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.
Page 33 Selection table of EMC filter by total length of servo motor power cable
The table shows that the available EMC filter is "HF3030C-SZL".
