New from Trinamic; The TMCM 6212 and 6213 six axis stepper controller and drive module

Overview:

The TMCM-6212 / TMCM-6213 is a six axis controller/drive module for 2-phase bipolar stepper motors with separate encoder (differential) and HOME / STOP switch inputs for each axis. tmcm-6212/3

CAN, RS485 and USB (Micro-USB) interfaces are available on the TMCM-6212 and EtherCAT™ together with USB (Micro-USB) on the TMCM-6213 for communication.

Furthermore the modules offer four analogue / digital inputs and four digital outputs together with a brake chopper unit (supporting an external regen resistor) for supply voltage limitation when energy is fed back into the supply rail.

* Unique Trinamic Features

StealthChop™:  Extremely quiet mode of operation for low and medium velocities. It is based on a voltage mode PWM. During standstill and at low velocities, the motor is absolutely noiseless. A StealthChop operated stepper motor is therefore ideal for indoor and domestic applications. Also motor operation is completely free of vibration at low velocities.

StallGuard2™: Trinamic’s patented stall detection is the world’s first sensorless high-resolution load detection implemented in a standard stepper motor drive. StallGuard2™ provides the ability to detect mechanical overload conditions and stall conditions without external sensors by measuring the load at a predefined point where step loss has not yet occurred.  This technology eliminates the need for reference or end switches reducing cost and complexity of applications that require them.

DCStep™:  While most open-loop stepper drives will lose steps in an overload situation, DcStep™ drives will reduce speed in order to overcome resistance. As a result, DcStep™ uniquely maintains position counter integrity.

CoolStep™: Sensorless, load dependent current control using the stallGuard2™ feature. CoolStep™ enables a stepper motor to be driven in a energy efficient way. Without CoolStep™, stepper motors are driven with constant current. Trinamic’s new TMC260, TMC261 and TMC262 stepper motor drives detect the actual motor load and adjust the current accordingly. This eliminates the safety current margin and boosts the motor current when required thus avoiding step loss and stalling. Reliability is therefore improved.
