Programming

■■

■ Inputs and outputs 300-328

In this parameter group, the

functions that relate to the input and

output terminals of the VLT

frequency converter are defined. The

digital inputs (terminals 16, 17, 18, 19, 27, 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.

of the internal 24 V DC supply from

the common potential of the external 24 V DC supply.
