TMCM-1276 Hardware Manual • Hardware Version V1.10 | Document Revision V1.00 • 2018-JUN-25 1 3 / 20 Features The TMCM-1276 is a complete stepper driver and controller solution with state of the art feature set. It is highly integrated and offers convenient handling via CAN interface. The TMCM-1276 includes driver electronics and a fully featured hardware motion controller. It can be used in many decentralized applications and has been designed for up to 3A RMS (4.
TMCM-1276 Hardware Manual • Hardware Version V1.10 | Document Revision V1.00 • 2018-JUN-25 1.2 1.2.1 4 / 20 TRINAMIC’s Unique Features stealthChop™ stealthChop is an 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. Thus, stealthChop operated stepper motor applications are very suitable for indoor or home use. The motor operates absolutely free of vibration at low velocities.
TMCM-1276 Hardware Manual • Hardware Version V1.10 | Document Revision V1.00 • 2018-JUN-25 5 / 20 stallGuard2 measurement value changes linearly over a wide range of load, velocity, and current settings. At maximum motor load, the value reaches zero or is near zero. This is the most energy-efficient point of operation for the motor. stallGuard2 Load [Nm] Initial stallGuard2 (SG) value: 100% Max. load stallGuard2 (SG) value: 0 Maximum load reached. Motor close to stall.
