ASMT Safety Precaution

ASMT Safety Precaution
3) To eliminate electrical noise on the encoder ensure adequate
separation of the motor power wires and the encoder wires.
4) Ensure that the motor ground wire is connected to the ground
terminal on the servo drive.
5) Do not perform either a hi-pot or megger-ohm test on any
encoder terminal.
6) Disconnect the motor from the controller before performing the
hi-pot or megger-ohm test on the motor.
Safety Precautions
Thank you very much for purchasing Delta AC servo motor. Installation and operation of this servo motor must be
in accordance with the Delta servo manual. Failure to read, fully understand and implement these safety
instructions and precautions may result in damage to the servo motor it’s drive, the machine to which it is
installed, or operator injury.
Transportation, Installation and Storage
Upon receipt of the motor, please perform the following:
1) Examine the appearance of the motor for any unusual marks.
2) Inspect the motor for any shipment damage.
3) Inspect the motor and encoder leads have not been damaged.
4) Verify the part number indicated on the nameplate corresponds with the
part number ordered.
If any items are damaged or incorrect, please contact your distributor or the
local Delta sales representative.
1) Do not carry or hold the servo motor by it’s wire harness or shaft. Incorrect
handling may cause damage to the motor / brake / encoder or personal
2) Do not hit the motor or shaft. Such shock can damage the disk inside the encoder.
3) Do not apply axial or radial loads to the motor
shaft that are in excess of the specified value.
4) The motor is not waterproof or oil-proof. Do not
install the motor where harmful gases or liquid
are present, or in an environment containing
excessive moisture or water vapor.
5) Do not store the motor where it will come into
contact with water, dust, corrosive gases and
6) Do not store the servo motor where it will be
subjected to vibration in excess of the specified
limits. Over time vibration may damage the servo
motor shaft and bearings.
7) Ensure that the storage of the motor meets the
environmental specification as stated on the motor data
8) Protect the motor and encoder from high electrical
1) Higher than maximum specified current may cause
motor demagnetization.
2) Before operation ensure that the motor, brake and encoder are connected correctly. Incorrect wiring will
cause permanent damage to one of more of the components.
1) The AC servo motor is designed to operate through a
dedicated Delta servo driver. Do not connect it directly to a
commercial power source (100/200V AC or DC, 50/60Hz).
The servo motor will not operate correctly and may be
permanently damaged.
2) The motor must be operated within its specified range.
Attention should given to ensure adequate cooling and
ventilation of the motor during operation.
3) The built-in brake is designed to hold the motor shaft when
stationary. It must not be used to dynamically brake or slow
down the motor during rotation. The motor brake is not designed as a safety feature for the attached
mechanism or machine. A separate safety device must be
installed on the machine to ensure adequate safety
measures are undertaken.
4) Should any abnormal odor, noise, smoke, temperature rise or
vibration be detected, stop the motor immediately, remove
power from the servo drive and isolate the motor.
1) There are no field serviceable parts on the motor / brake /
2) Do not disassemble the motor.
3) Any disassembly will void the factory warranty.
4) Disassembly will cause permanent damage to the motor /
brake and encoder.
5) Protect the motor from any splashing or airborne liquids.
WARNING: Failure to read, fully understand and implement these safety instructions and
precautions may result in damage to the servo motor it’s drive, the machine to which it is
installed, or operator injury.
