(4) Number of secondary side (magnets)
(Max. feed distance) + (Length of primary side (coil)) = 1600 + 224 = 1824 [mm]
As a result of this, the total length of the secondary side (magnet) that is set out needs 1824mm or more.
For example, one of the following examples can be selected..
(a) Four LM-H2S20-480 magnets (Total of 1920mm)
(b) Five LM-H2S20-384 magnets (Total of 1920mm)
(c) Seven LM-H2S20-288 magnets (Total of 2016mm)
(d) Two LM-H2S20-768 and one LM-H2S20-288 magnets (Total of 1824mm)
(5) Calculation of regenerative energy

{203.8 0.2 (2/2) (80/100) 11}/2
＝
10.8[W]
(Use MR-J3-70B-RJ004U502 for the servo amplifier.)
As the regenerative energy does not exceed the regenerative power (20W), the regenerative brake option
is not required.
