■ Inputs and outputs 300-328

In this parameter group, the

functions that relate to the

input and output terminals

of the frequency converter

are defined. The digital

inputs (terminals 16, 17, 18,

19, 27, 29, 32 and 33) are

programmed in parameters

300-307.

The table below gives the options for programming

the inputs. The digital inputs require a signal of 0 or

24 V DC. A signal lower than 5 V DC is a logic ‘0’,

while a signal higher than 10 V DC is a logic ‘1’.

The terminals for the digital inputs can be

connected to the internal 24 V DC supply, or an

external 24 V DC supply can be connected.

The drawings in the next column show one Setup

using the internal 24 V DC supply and one Setup

using an external 24 V DC supply.

Switch 4, which is

located on the Dip

switch control card,

is used for separating the common potential of the

internal 24 V DC supply from the common potential

of the external 24 V DC supply. See Electrical

installation.

Please note that when Switch 4 is in the OFF

position, the external 24 V DC supply is galvanically

isolated from the frequency converter.
