Set U806.02 like U806.01
Set P083 depending on the source of the
actual speed value
Rated
P100 =
Number
Set P648, P649 depending on the source
of the control word
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.
