Integration
The SIMOTICS T-1FW6 built-in torque motors supplied via the
SINAMICS S120 drive system are designed for operation on a
600 V DC link voltage level.
The cable connection is brought out of the front face of the stator.
The cable end has a pre-assembled connector or exposed
cable cores depending on the motor version. The length of the
power and signal cables from the motor to the drive system must
not exceed 50 m (164 ft).
Absolute measuring systems with DRIVE-CLiQ
Measuring systems with integrated DRIVE-CLiQ interface are
available from various manufacturers. The encoders can be
used as a motor feedback system.
An up-to-date list of the relevant manufacturers and available
measuring systems can be viewed on the Internet at:
It is also possible to use absolute measuring systems with
EnDat 2.1 or incremental systems with 1 V
