5.6.4 Control terminals – Connection diagrams of configura-
tions
The control hardware and the software of the frequency inverter are freely configur-
able to a great extent. Certain functions can be assigned to the control terminals, and
the internal logic of the software modules can be freely selected.
Thanks to the modular design, the frequency inverter can be adapted to a great
range of different driving tasks.
The demands made of the control hardware and software are well known in the case
of standard driving tasks. This control terminal logic and internal function assign-
ments of the software modules are available in standard configurations. These as-
signments can be selected via parameter
Configuration
30. The configurations are
described in the following section.
Note:
The ACU units of the ACTIVE Cube series feature the function STO
(„Safe Torque Off“). If this function is not required, the “Controller re-
lease” signal must be connected to inputs S1IND/STOA and
S7IND/STOB.
Inputs S1IND/STOA and S7IND/STOB are connected in series.
Warning! If the same signal is used for the digital inputs S1IND/STOA and S2IND,
safe disconnection of power supply to the motor according to safety
function STO („Safe Torque Off “) is not guaranteed.

Note:
The control methods 2xx can be used with HTL sensors (with or with-
out reference track) connected to the basic device or to an extension
module.
The control methods 2xx with TTL sensors require an extension mod-
ule.
An extension module EM-RES for evaluation of resolver signals is re-
quired for operation of a synchronous machine (control method 5xx).
