Redundancy in Master/Follower crane control
In the Master/Follower crane control, redundancy is implemented using a spare drive
unit that is ready to be used as a Master or a Follower. The spare unit usually
replaces the faulty Master or one of the Followers.
Adaptive Programming provides the ability to switch between the Master, Follower or
standby (spare unit) mode. This means that the Master and Follower are no longer
fixed, but can be changed when needed.
For more information, see the
Application Guide for Adaptive Program
(3AFE64527274 [English]) and
DriveAP User’s Manual
(3AFE64540998 [English]).
When you use a spare unit, the ACS800 motor output must be provided with an
interlock power switch. The spare unit must be connected to the Master/Follower
optical fibre ring network (communication channel 2). All RMIO control boards of the
drives must be powered on with the external power supply (see
on page
).
The spare unit is normally in the standby mode.
The following figure shows a Master/Follower standby configuration with output
contactors and encoder splitters.
The following figure shows an example of a main circuit diagram with a Master, a
Follower and a standby unit together with output interlock power switches.
