4.3 I/O interfaces
4.3.1 IOEC I/O modules
Internal and external, analog and binary I/O signals are connected to the control system by
IOEC modules.
The standard I/O includes one external module (IOEC 2, IOEC 3) and one module that is internal
to the drive operation (IOEC 1). The standard I/O provides standard control and supervision
functionalities sufficient for most applications.
The drive can include an optional expansion I/O that includes an external module (IOEC 4).
These expansion modules provide extra inputs and outputs for control and supervision as may
be required by the drive or the customer to support various control options.
