Set U806.02 like U806.01
P082 <> 0
Set P083 depending on the source of the
actual speed value

P100 =
Number
Set P648, P649 depending on the source
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.
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.
