Smooth tune control
The Smooth tune control - is a largest advantage of PoStep25-256 in front of others drivers on market.
Intelligent stepper motor control, increasing stepper motor efficiency and system performance,
eliminate motor noise at low speeds and at standby. Making the control precise.
Board use requirements
Step, direction and enable inputs. 9-30 VDC power supply, connected bipolar stepper motor
before
applying power.
Do not connect or disconnect a motor while the driver is energized. This could cause
permanent damage to the driver.
