１．Safety１－１．Safety Precautions(1) This product is not designed or manufactured for application for equipment
requiring high level of reliability such as equipment related to nuclear
energy, aeronautics-related equipment, automobiles, ships, medical appliances
directly handling the human body and equipment that might seriously affectproperties.
(2) This product is for a devices inclusion.
Please establish it into enclosure without fail.
(3) Ensure to use this product according to the method specified
in the Instructions Manual and within the specifications.
(4) Depending on the operational conditions, the stepping motor may step out when
it is on holding-state or driving-state.
In particular, the load in transport may fall if the motor steps out on thevertical drive (such as the Z-axis).
Start operation after test run for deliberate confirmation of operation.

Deterioration of the holding power withthe motor may cause breakage of the machineor injury.
Check safety before inputting.

① Operating current range : 4mA～5.3mA
The photo-coupler turns on withinter-terminal voltage of 19.1 V～25.1 V.
(Photo-coupler diode V F≒ 1.1 V)● Motor output current is shut off with the photo-coupler ON.
At this time, motor torque changes to detent torque.
● When this signal is input, motor torque may be lost, resulting in failure toretain the load transported.
In particular, this risk is high with the vertical drive (such as the Z-axis).

１０－３．Overheat alarm (O.H.A）LEDIOverheating may cause fire.
Stop operation upon output of this signal.

● In case of internal temperature of the driver reaches approx. 70℃ or more,
O.H.A LED comes on. At this time the motor output current is not blocked.
● When this LED comes on, stop operation and check if there is any
abnormality occurring with the motor and the driver.
● Provide mechanical cooling, for example, if this LED comes on while
no abnormality is detected.
● Continuous operation is possible unless this LED comes on.

Instructions Manual

１０－６．Torque Characteristics(1) Representations in the torque characteristics table are made in terms of the
motor rotation (s -１) vs. torque (N・m).
Motor rotation (s -１) and drive pulse frequency (Hz) are converted as follows:

Motor rotation(s -１) ×360°＝ Drive pulse input frequency(Hz)Step angle● Maximum value of the rotate speed is 60s -1 at 0.72゜ motor.
(2) The Maximum Starting Pulse Rate is represented as "fs" by the value at zeroinertial load.
(3) Upon operation, provide adequate allowance for torque.
(4) The stepping motor may attain high temperature, depending on the operational
conditions.
If the surface temperature exceeds 100℃, provide cooling measures to control
it to operate at 100℃ at the highest.
