6.4 AS interface as I/O expansion of the frequency inverter control terminals
By means of the AS interface module the number of digital inputs and outputs on the frequency inverters or
made available by the use of a customer interface can be expanded by 4 further inputs and two outputs.
Via the 4 sensor inputs (Sensor Dig In / Bus IO In Bits 4 to 7) all functionalities specific to the frequency
inverter can be assigned or parameterised via the parameter arrays in parameter P480. The possible settings
are described in Section 4.1.
The following example serves purely for the expansion of the input and output range of the frequency inverter
without field bus connection. The connection of the yellow AS interface cable (PWR) is not necessary for this
application, however, a 24V power supply (AUX) to the module is essential. In addition to the possibility of
connection via the digital inputs on the control connections, via the 4 AS interface module sensor inputs,
additional functionalities for a Posicon application and the use of an SK 530E are illustrated. For this, the
following FI parameters must be set as follows:
Function requirement for SK 530E with SK TU3-AS1 option:
ƒ Manual, semi-automatic and automatic operation, i.e. parameter switch-over
ƒ PS 1 manual operation. PS2 semi-automatic, PS3 automatic ("PS" = Parameter set)
ƒ 15 absolute positions
ƒ Direction of rotation right and left
ƒ PTC connection
ƒ Reference point run
ƒ Reference point
ƒ External brake
ƒ Error indication
ƒ Current limit
ƒ Torque current limit
ƒ Reference point
ƒ Position reached
