4.2.2.7. Operating modes
The drive provides the following operating modes:
–
Master-follower operating mode:
used for applications with several drives
where the motor shafts are coupled to each other (eg, gearing, chain, belt).
Owing to the master- follower operating mode the load can be evenly
distributed between the drives or at some adjustable other ratio which
depends on the process.
–
Hand-auto operating mode:
suitable for applications where the speed has to be
controlled automatically by a process automation system and manually by an
external control panel. The active control station is selected via a digital input.
The operating mode is also recommended when two external control stations
exist from where the reference value can be set and the drive can be started
and stopped. The external control station is selected via a digital input.
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.
