Encoder, Sensor Modules
● The motor encoder or Sensor Module should be connected to the associated Motor
Module.
Connecting the motor encoder via DRIVE-CLiQ:
– Single Motor Module Booksize to terminal X202
– Double Motor Module Booksize motor X1 to terminal X202 and motor X2 to terminal
● If possible, Sensor Modules of direct measuring systems should not be connected to the
DRIVE-CLiQ line of Motor Modules, but rather to free DRIVE-CLiQ sockets of the Control
Unit.
Note
This restriction does not apply to star-type connections for the Motor Modules.
Voltage Sensing Modules
● The Voltage Sensing Module (VSM) should be connected to the DRIVE-CLiQ socket
X202 (booksize format) of the associated Line Module/Motor Module.
– If the DRIVE-CLiQ socket X202/X402 is not available, a free DRIVE-CLiQ socket on
Terminal Modules
● Terminal Modules should be connected to DRIVE-CLiQ socket X103 of the Control Unit in
series.
● If possible, Terminal Modules should not be connected to the DRIVE-CLiQ line of Motor
Modules, but rather to free DRIVE-CLiQ sockets of the Control Unit.
Note
This restriction does not apply to star-type connections for the Motor Modules.
