Toshiba TB67S109 Stepper Motor Driver

TB67S109 Stepper Motor Driver, supplied including cooler.

Parameters:

• Adjustable current limitation
• Max current: 4A with active cooling
• Thermal protection
• Current protection
• 6 resolutions:
  • full-step,
  • half-step,
  • 1/4- step,
  • 1/8- step,
  • 1/16- step
  • 1/32- step

• Supply voltage: max. 50V

Maximum current limitation:

• Current limits can be set with a trimmer and Vref measurement. Connect the voltmeter [+] to Vref and [-] to GND and read the voltage value.
• The module uses 0.10Ohm measuring resistance, so the current limits can be calculated according to the formula: current limit = Vref x 2; for example for 2A, set the trimmer to 1V.
