Stepping Motor Drivers
BD63510EFV
●General Description
BD63510EFV series are stepping motor drivers of 1/16
micro step(sixteenth step) drive. As for its basic
function, it is a low power consumption bipolar PWM
constant current-drive driver with power supply rated
voltage of 36V and rated output current (DC) of 1.0A.
The input interface is CLK-IN type.
There are step modes of Full step & Half step, Quarter
step, Sixteenth step mode by internal DAC (D-A
converter), and for current decay mode, the ratio of
FAST DECAY & SLOW DECAY can be freely set, so the
optimum control conditions for every motor can be
realized. In addition, being able to drive with one system
of power supply makes contribution to the set design’s
getting easy.
