1 Features
The TMC211 is a combined micro-stepping stepper motor motion controller and driver with RAM and
OTP memory. The RAM or OTP memory is used to store motor parameters and configuration settings.
The TMC211 allows up to four bit of microstepping and a coil current of up to 800 mA. After
initialization it performs all time critical tasks autonomously based on target positions and velocity
parameters. Communications to a host takes place via LIN. Together with an inexpensive
microcontroller the TMC211 forms a complete motion control system. The main benefits of the
TMC211 are:
•
Motor driver
•
Controls one stepper motor with four bit microstepping
•
Programmable Coil current up to 800 mA
•
Supply voltage operating range 8V ... 29V
•
Fixed frequency PWM current control with automatic selection of fast and slow decay mode
•
Full step frequencies up to 1 kHz
•
High temperature, open circuit, short, over-current and under-voltage diagnostics
Motion controller
•
Internal 16-bit wide position counter
•
Configurable speed and acceleration settings
•
Build-in ramp generator for autonomous positioning and speed control
•
On-the-fly alteration of target position
•
reference switch input available for read out
LIN interface
•
Physical and Data-Link Layers conform to LIN specification rev. 1.3
•
Field-programmable node addresses (128)
•
Dynamically allocated identifiers
•
Diagnostics and status information as well as motion parameters accessable
•
LIN bus short-circuit protection to supply and ground
•
Lost LIN safe operation
