Control mode
A: Default potentiometer control (5K-100K),defaults 10K;
B: MACH3 -PWM speed control signal input, external PWM input requirements: level 3.5-12V VPP, frequency 1K-10KHZ, suitable for MACH3 spindle speed control.
Rated current: 10A, overload and short circuit protection current 12A. (Over-current cut output, over current indicator flashes, the potential light is off, over current lift).
Soft-start function. Prevent excessive current caused by the motor and power damage (default 0 seconds soft start), 0-5 seconds adjustable.6.Control power: 12V120W, 24V240W, 36V360W, 48V480W, 60V600W7.
