Input Motor is rotated by setting number of pulses.
* Internal circuit of the motor driver works when the first pulse
becomes ON and the last pulse becomes OFF.
Input The direction of the motor rotation is determined by setting the
level of signal.
"L".....Clockwise direction (as seen from the output shaft)
"H"....Counterclockwise direction (as seen from the output shaft)
Note:
When the MOTMD3-0 is "L", do not change the rotation
direction within 6.25µsec. before the first pulse of the
MOTCLK-1 becomes ON and after the last pulse
becomes OFF.
Input Excitation drive is forcibly turned ON/OFF.
"H"....Normal operation (Excited)
"L".....Excitation drive is forcibly shut off (Not excited)
Input Motor wire current value is set in the range of 0 to 3 (A)/phase
by applying the analog voltage 0 to 5 (V).
Input Set the excitation mode.
Note:
Do not change the setting within 5µsec. after the first
pulse of the MOTCLK-1 becomes ON and the last pulse
becomes OFF.
Input Reset for the whole system.
Internal circuit of the driver is initialized by setting the motor to
"L" level (pulse interval: 10µsec. or more).
