Figure 9-25 Encoder system connection via a Sensor Module Cabinet-Mounted SMC40
The wiring diagram shows two different applications of the SMC40. For each conversion of an
EnDat 2.2 encoder signal into a DRIVE-CLiQ signal, a dedicated DRIVE-CLiQ cable must be used,
as the electronics in the SMC40 is designed so that each channel is independent. The DRIVE-CLiQ
cables cannot be interchanged.
Connecting a standard motor with brake and optical encoder
A standard motor with gearbox for a rotary indexing table drive is shown in the connection
example. The rotary indexing table has an angular position measuring system with EnDat 2.2
interface. The measured angular data are transferred via EnDat 2.2 to the SMC40 and from there
via DRIVE-CLiQ to the Control Unit.
The motor contains an integrated encoder and temperature evaluation, which transfers data via
DRIVE-CLiQ directly to the Motor Module.
Connecting a linear motor without DRIVE-CLiQ interface
From a linear motor with linear scale, velocity and position are first transferred via the EnDat 2.2
connection to the SMC40 and from there, via DRIVE-CLiQ to a Terminal Module TM120.
