SIMOTRAS HD Operating Instructions
6.3.2 Parameterization of SIMOTRAS converters for parallel connection
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 = 167 Actual 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
U806.01 = 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
U806.01 = 2 1 slave
U806.01 = 2 and 3 2 slaves
U806.01 = 2, 3 and 4 3 slaves
U806.01 = 2,3,4 and 5 4 slaves
U806.01 = 2,3,4,5 and 6 5 slaves
Set U806.02 like U806.01
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
P635.F = 167 Use actual speed value of master as
setpoint
P100 =
units SIMOTRAS of Number
current motor Rated
P100 =
units SIMOTRAS of Number
current motor Rated
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
P820.01 = 23 Suppress fault message F023
P820.02 = 24 Suppress fault message F024
P820.03 = 31 Suppress fault message F031
P821.01 = 23 Suppress alarm A023
P821.02 = 24 Suppress alarm A024
P821.03 = 31 Suppress alarm A031
For further details about the operating principle of parallel connections between SIMOTRAS
converters, please refer to Section 8, Function Diagrams, Sheet G195 (paralleling interface).
Note:
All control commands (travel command 1, etc.) must be connected to a group of parallel-connected
SIMOTRAS converters via the master device.
