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 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 124 ).

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.
Settings
Parameter group 13 Standard AO (page 128 ).

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 65 ).
Digital input/output DIO1 can be used as a frequency input, DIO2 as a frequency
output.
Settings
Parameter groups 10 Standard DI, RO (page 113 ) and 11 Standard DIO, FI, FO (page
119 ).

Programmable relay outputs
The control unit has three relay outputs. The signal to be indicated by the outputs can
be selected by parameters. The relay outputs on the control unit are updated on a 0.5
ms time level.
Settings
Parameter group 10 Standard DI, RO (page 113 ).
