SIMOREG DC Master Operating Instructions
For further details about the operating principle of parallel connections between SIMOREG
converters, please refer to Section 8, Function Diagrams, Sheet G45 (paralleling interface).
Notes:
In this mode it is possible to maintain operation with the remaining SIMOREG units if one unit
should fail (e.g. fuse blown in the power section). The functional SIMOREG units continue to run
without interruption if one unit fails. During configuration, make sure that the power of only n units
(instead of n+1 units) is sufficient for the application.
• Control commands "Switch-on/Shutdown", "Enable operation", "Emergency stop" etc. must be
connected to a group of parallel-connected SIMOREG converters via the master device AND via
the "standby" master device.
Terminals 37 and 38 must be permanently connected to terminal 34 on the slaves!
• The speed setpoint and the actual speed value must be connected to a group of parallel-
connected SIMOREG converters via the master device AND via the "standby" master device. !
• All parameters except for those in the above list must be set identically on the master and the
"standby" master.
• Optimization runs must be started on the master device. All slaves must be connected and
ready to run when optimization is started.
