To limit the switching voltage peaks, a zinc oxide varistor (R
U
) must be
connected in parallel to the controller output.
For long motor cables (> 50 m) or motors which are connected in parallel, it
may be necessary to use an interference suppression module (see chapter 3
"Accessories")
Braking circuit:
1)
Interference suppression module
2)
Mains choke is only required for type 534
