Inputs and outputs 300-365
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.
