6 / 74 page  TMC5031 DATASHEET (Rev. 1.11 / 2016-APR-28) 6 www.trinamic.com 1.7 coolStep – Load Adaptive Current Control coolStep drives the motor at the optimum current. It uses the stallGuard2 load measurement information to adjust the motor current to the minimum amount required in the actual load situation. This saves energy and keeps the components cool, making the drive an efficient and precise solution. Benefits are: - Energy efficiency power consumption decreased up to 75% - Motor generates less heat improved mechanical precision - Less or no cooling improved reliability - Use of smaller motor less torque reserve required → cheaper motor does the job Figure 1.2 shows the efficiency gain of a 42mm stepper motor when using coolStep compared to standard operation with 50% of torque reserve. coolStep is enabled above 60RPM in the example. 0 0,1 0,2 0,3 0,4 0,5 0,6 0,7 0,8 0,9 0 50 100 150 200 250 300 350 Efficiency Velocity [RPM] Efficiency with coolStep Efficiency with 50% torque reserve Figure 1.2 Energy efficiency with coolStep (example) |
