SIMOREG DC Master Operating Instructions
6.3.2 Parameterization of SIMOREG converters for parallel connection
6.3.2.1 Standard operating mode
Master Slaves
U800 = 1 Paralleling interface active U800 = 2 Paralleling interface active
Use master firing pulses
U803 = 0 "N+1 mode" not active
U804.01 = 30 control word 1
U804.02 = 31 control word 2
U804.03 = 167Actual speed value
U804.01 = 32 status word 1
U805 = 1 (bus termination) on the two end units
(at both physical ends of the bus cable)
0 (no bus termination) on all other units
U806 = 12 master for one slave
13 master for 2 slaves
14 master for 3 slaves
15 master for 4 slaves
16 master for 5 slaves
Set U806.02 like U806.01
U806 = 2 1 slave
U806 = 2 and 3 2 slaves
U806 = 2, 3 and 4 3 slaves
U806 = 2,3,4 and 5 4 slaves
U806 = 2,3,4,5 and 6 5 slaves
Set U806.02 like U806.01
P082 <> 0 operating mode for field P082 = 0 internal field is not used
Set P083 depending on the source of the
actual speed value
P083 = 4 Freely connected actual speed value
P609 = 6023 Use actual speed value of master
P100 =
unitsSIMOREGofNumber
currentmotorRated
P100 =
unitsSIMOREGofNumber
currentmotorRated
Set P648, P649 depending on the source
of the control word
P648 = 6021 Use control word 1 from master
P649 = 6022 Use control word 2 from master
P821.01 = 31 Suppress alarm A031
P110 = Actual armature resistance
x no. of SIMOREG converters
P111 = Actual armature inductance
x no. of SIMOREG converters
The optimization run for current controller
and precontrol (P021 = 25) sets these
parameters correctly.
P110 = set as on master
P111 = set as on master
For further details about the operating principle of parallel connections between SIMOREG
converters, please refer to Section 8, Function Diagrams, Sheet 41 (paralleling interface).
Notes:
• 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.
Terminals 37 and 38 must be permanently connected to terminal 34 on the slave !
• Optimization runs must be started on the master device. All slaves must be connected and
ready to run when optimization is started.
