70 DC1 variable frequency drive 12/13 MN04020003Z-EN www.eaton.com
The DC1 variable frequency drive has four control inputs (control signal termi-
nals 2, 3, 4, and 6). Two of these are parameterizable as digital control inputs;
while the others can be set to work as digital or analog control inputs.
The variable frequency drive comes with the following default setting:
• Control signal terminal 2 as digital input 1 (DI1),
• Control signal terminal 3 as digital input 2 (DI2),
• Control signal terminal 4 as digital input 3 (DI3),
• Control signal terminal 6 as analog input 1 (AI1).
Control signal terminal 8 can be used as a digital or as an analog output. It is
used as an analog output (AO) in the default configuration that comes with
the variable frequency drive when it is delivered.
