Notes for Proper Use of Megatorque Motor System
1. For Safety Use of the Products
 This product is intended for the uses of general industry, and is not designed and/or manufactured for the uses
involving human lives.
 When you consider to use this product for special uses such as nuclear control, aero-space devices, traffic control,
medical devices, various safety devices or such systems, please contact us.
 Although this product is manufactured under strict quality control, be sure to provide safety equipment for
applications to the facility which can cause serious accidents or losses due to the failure of this product.
2. Precautionary statement for the prolonged use of the Driver Unit
1) Temperature
 Keep the ambient temperature of the Driver Unit within 0 to 50[°C]. You cannot use the Driver Unit in a high
temperature atmosphere over 50[°C]. Keep a clearance of 100 mm in the upper and the lower side of the Driver Unit
when it is installed in an enclosure. If heat is built up on the upper side of the Driver Unit, provide ventilation openings
on the top surface or equip a forced air cool unit to take the heat out of the Driver Unit. (Measures against contamination
are required for the ventilation openings.)
2) Dust-proof and Waterproof
 Put the Driver Unit in an enclosure with the protection code of IP54 or better. Protect the Driver Unit from oil-mist,
cutting oil, metal chips and paint fume, etc. Otherwise it may result in failure of electric circuits of the Driver Unit.
(The IP code is to specify the protection level of enclosures from solid contamination and water. It is specified in the
IEC standard and other safety regulations.)
3) Wiring/Ground
 Refer to the User's Manual for proper wiring.
 When wiring and installing the Driver Unit, take appropriate measures not to contaminate it.
 Use the product by adhering to power specifications of Driver Unit.
 For IO cable of CN2 control, use the one with cable length shorter than 2[m].
 For CN0 USB communication cable, use the double-shielded one with length shorter than 3[m], and for the connector
at Driver Unit side, use USB mini-B.
4) Storing
 Store the Driver Unit in a place at where it is not exposed to rain, water, and harmful gas or liquid.
 Store the Driver Unit in the place at where it is not exposed to direct sunlight. Keep the ambient temperature and the
humidity as specified.
5) The limited number of times for overwriting data to EEPROM.
 The EEPROM is used to backup all data and programs. However, the number of times for overwriting is limited to
approximately 100 000 times.
