SINAMICS S120 Installation and Start-Up Manual, 12/04 Edition
Rules for FW2.2:
S Only one Active Line Module can be connected to a Control Unit.
S The default sampling times must not be changed.
S A Double Motor Module must not be operated as a single drive.
S Mixed operation (servo with vector V/f) is possible.
S A maximum of nine Sensor Modules can be connected.
S The Active Line Module (booksize) and Motor Modules (booksize)
– can be connected to one DRIVE-CLiQ line in servo mode.
– must be connected to separate DRIVE-CLiQ lines in vector mode.
S During mixed operation (servo and vector V/f), separate DRIVE-CLiQ lines
must be used.
S The Active Line Module (chassis) and the Motor Modules (chassis) must be
connected to separate DRIVE-CLiQ lines.
S Motor Modules (chassis) with different pulse frequencies must be connected to
separate DRIVE-CLiQ lines.
