1) Built-in brake chopper is only available on 3-phase units.
2) Terminal 53 can also be used as digital input.
3) Switch S801 (bus terminal) can be used to enable termination on the RS485 port (terminals 68 and 69).
4) Refer to chapter 6 Safe Torque Off (STO) for the correct STO wiring.
5) The S2 (single-phase 200–240 V) frequency converter does not support load sharing application.
