INFO
The TMCM-171 is a controller / driver module for high perfor-
mance servo drives based on brushless DC motors. It combines
the high resolution of a stepper motor coupled with the high
dynamic, high velocity and high reliability of a BLDC drive. The
motor and switches can be connected easily with pluggable
screw terminals. A build-in ramp generator allows parameter-
ized smooth positioning. The TMCM-171 supports BLDC motors
with nearly any number of poles and incremental encoders with
nearly any resolution.
The TMCM-171 integrates a velocity regulator, a position
regulator and a ramp generator. The module can be controlled
remotely via CAN or RS-485 interface. Additionally, the TMCM-
171 is equipped with a step direction interface. Stand alone
operation (either via TMCL program or via analog control) is
also possible.
The housing is based on an aluminium plate which is used as
a heatsink. The TMCM-171 fits perfectly to the QBL5704 BLDC
motors.
