Input/output signals
Clock input MOTCLK Inpu
t
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.
Set the direction of
motor rotation
MOTDIR Inpu
t
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:
Do not change the rotation direction within
7µsec. before the first pulse of the MOTCLK
becomes ON and after the last pulse becomes
OFF.
Cut off the drive out-
put
MOTEN Inpu
t
Excitation drive is turned ON/OFF.
“H” .... Normal operation (Excited)
“L”..... Excitation drive is forcibly shut off (Not excited)
Voltage to set value
for the motor current
MOTREF Inpu
t
Motor wire current value is set in the range of 0 to 1.7
(A)/phase by applying the analog voltage 0 to 5 (V).
Set the excitation
mode (1) to (3)
MOTMD 1 to 3 Inpu
t
Set the excitation mode.
Note:
Do not change the setting within 7µsec. after
the first pulse of the MOTCLK becomes ON and
the last pulse becomes OFF.
Reset MOTRST Inpu
t
Reset for the whole system
Internal circuit of the driver is initialized by setting the
motor to “L” level (pulse interval: 10µsec. or more).
The motor drive circuit is automatically reset when the
power is turned ON.
