Control terminals are freely configurable.
Control „Safe Torque Off “: Contacts on X210A.3 and X210B.2 open.
Release of frequency inverter: Contacts on X210A.3 and X210B.2 closed.
Note:
By default, the different configurations occupy the control terminals with certain settings.
These settings can be adjusted to the specific application, and various functions can be
assigned freely to the control terminals. An overview of the settings is displayed at the
last but one page of these operating instructions.
