１．Safety１－１．Safety Precautions
WARNING(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) Do not use or keep the product in explosive or corrosive environments,
in the presence of flammable gases, locations subjected to splashing water,fine particles, soot, steam, or exposed to radiation or direct sunshine.
Doing so may cause injury or fire.
(3) For the driver's power supply, use a DC power supply with reinforced insulation
on its primary and secondary sides.
Failure to do so may cause electric shock.
(4) This product is designed for use within machinery,
within an enclosure.
Failure to do so may cause injury.

so it should be installed(5) Do not transport, move, install the product, perform connections or inspections
when the power is on.
Doing so may cause electric shock, injury or fire.
(6) Only qualified personnel are allowed to transport, move, install the product,
perform connections or inspections.
Failure to do so may cause injury or fire.

CAUTION(7) Do not touch the driver during operation or immediately after stopping.
Doing so may cause burn on the skin due to overheating of the driver.
(8) Ensure to use this product according to the method specified
in the Instructions Manual and within the specifications.
(9) 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.
(10) Provide fail-safe measures so that the entire system may operate in a safe
mode even in cases of the external power supply failure, disconnection of thesignal line, or any failure on the driver.

６－３．Connecting DC Input/Motor Output Connector（Ｊ２，Ｊ３）
CAUTION
Erroneous connection may cause
breakage of the motor or the driver.
Correctly connect the DC Input/Motor
output connector.

The following items are required:●Housing for J2 (51067-0200:Molex)●Housing for J3 (51067-0500:Molex)●Contact for J2,J3 (50217-9101:Molex)●Manually operated crimping tool
for AWG24-18(57189-5000:Molex)

One unit
One unit
7 contacts
One unit(1) Crimp the contact to the cable used for wiring.
(2) Insert the contact into the housing.
Make sure that the housing No. and the connector No. on the main frame arematched before inserting the contacts.
(3) Connect the housings to the connectors on the main frame.
● The contacts for J2(for DC input) are 2 pieces, and for J3(motor output)
are 5 pieces.
● When inserting, keep pushing J2,J3 housings into the connectors until it islocked. Also, check if the contacts are not displaced from the housing.
