3.3 I/O interfaces
3.3.1 IOEC I/O modules
Overview
Internal and external, analog and binary I/O signals
are connected to the control system by IOEC mod-
ules.
The standard I/O includes one external module
(IOEC 2) and one module that is internal to the
drive operation (IOEC 1). The standard I/O pro-
vides standard control and supervision functional-
ities sufficient for most applications.
The drive can include optional expansion I/O that
includes an external module (IOEC 4) and an inter-
nal module (IOEC 3). These expansion modules pro-
vide extra inputs and outputs for control and
supervision as may be required by ABB or the cus-
tomer to support various control options.
