HOLD current:
Approx. 40 % of DRIVE current value factory-set
Can set the DRIVE current with a DRIVE I. SEL switch in conformity to an application motor.
In addition, user can set the HOLD current by the ratio approx. 10 % - 100 %
with the DRIVE

Moreover, the resolution set with the switch by the C.S signal operation from the application
can be switched to 0.036
step.

The motor can be driven at high speed by switching the C.S signal from the application when
・
the setting of resolution is high.

Motor excitation
The stepping motor output current can be intercepted by the M.F signal operation from the
current ON/OFF
application. As a result,
The manual operation of the machine can be done.
･
Generation of heat of the motor can be lowered.
･
At this time, the holding torque of the motor is lost.
CAUTION
Deterioration of the holding power with the motor may cause breakage of the machine or
injury. Check safety before inputting.
When this signal is input, motor torque may be lost, resulting in failure to retain the load
transported. In particular, this risk is high with the vertical drive such as the Z-axis .

Warning of
When the temperature in the unit reaches at the temperature approx. 70
for which cooling
(
℃)
overheat
is necessary, driver alarm signal DALM
status is outputted.
(
)
Moreover, LED of overheating warning O.H.A: Red color
is lighted.
(
)
Consecutive driving is possible in the range where this signal is not output.
・
The motor output current is not intercepted at the time of ON this signal.
・
When DALM is enabled by the setting of the controller's department, the motor can be
・
stopped automatically.
WARNING
May be fired by overheat.
When this signal output, please stop driving.
Confirm whether abnormality occurred at the motor and the product.
When this signal is turned on with abnormality not found, please enlarge the installation base
or give cooling of the forced air cooling etc.

P.O detection
The P.O signal is generated only once in the pulse number hit that rotates by 7.2
by setting
°
each resolution.
When this signal is set as a origin detection signal of the controller's department, a highly
accurate machine origin point can be detected.
