Control interfaces

Programmable analog inputs
The control unit has two programmable analog inputs. Each of the inputs can be
independently set as a voltage (0/2…10 V or -10…10 V) or current (0/4…20 mA)
input by a jumper or switch on the control unit. Each input can be filtered, inverted
and scaled. The analog inputs on the control unit are read on a 0.5 ms time level.
The number of analog inputs can be increased by installing FIO-11 or FAIO-01 I/O
extensions (see
Programmable I/O extensions below). The analog inputs on
extension modules are read on a 2 ms time level.
The drive can be set to perform an action (for example, to generate a warning or fault)
if the value of an analog input moves out of a predefined range.
Settings
Parameter group 12 Standard AI (page 159 ).

Programmable analog outputs
The control unit has two current (0…20 mA) analog outputs. Each output can be
filtered, inverted and scaled. The analog outputs on the control unit are updated on a
0.5 ms time level.
The number of analog outputs can be increased by installing FIO-11 or FAIO-01 I/O
extensions (see
Programmable I/O extensions below). The analog outputs on
extension modules are updated on a 2 ms time level.
Settings
Parameter group 13 Standard AO (page 163 ).

Programmable digital inputs and outputs
The control unit has six digital inputs, a digital start interlock input, and two digital
input/outputs (I/O that can be set as either an input or an output). The digital inputs on
the control unit are read on a 0.5 ms time level.
One digital input (DI6) doubles as a PTC thermistor input. See section Motor thermal
protection (page 80 ).
Digital input/output DIO1 can be used as a frequency input, DIO2 as a frequency
output.
The number of digital inputs/outputs can be increased by installing FIO-01, FIO-11 or
FDIO-01 I/O extensions (see
Programmable I/O extensions below). The digital inputs
on extension modules are read on a 2 ms time level.
