Linear Motor and Third-Party Motor
Wiring
If the current exceeds the maximum current in the specifications, the coil assembly of the

linear motor may overheat, and thus be damaged. Contact the distributor or local Delta
11
sales representative if this problem occurs.
 Make sure the wiring of the linear motor is correct. Incorrect wiring will lead to abnormal
operation, malfunction, or damage of the linear motor.
 The linear motor must be correctly grounded.
 When the linear motor is undergoing high-voltage component tests, cut off the power
supply to the controller. To maintain the product lifespan, do not perform this kind of test
unless necessary.
Operation
 Use the servo drives which are designed for driving the linear motors. Do not directly
connect a commercial type power supply (100/200V, 50/60 Hz) to the linear motor circuit;
otherwise the motor cannot operate normally and may be permanently damaged.
 Make sure there is no obstacle between the coil assembly and the magnet shaft.
 Follow the linear motor specifications when using the product. The motor's operation
temperature must not exceed the specified range.
 If there is any odor, noise, smoke, heat, or abnormal vibration during motor operation,
stop the motor and turn off the power immediately.
 When the linear motor is operating, reserve an air gap between the coil assembly and the
magnet shaft according to the specifications. When the air gap is too large, it might lower
the motor performance; when the air gap is too small, the assembly coil might be in
contact with the magnet shaft.
Other precautions
 Delta linear motors have no user-replaceable parts.
Do not disassemble the linear motor or replace its parts, or it will void the warranty.

 Disassembling the linear motor may lead to permanent malfunction or damage of the motor.
 Do not splash any water or oil on the product.
Air gap specification
 To ensure the thrust is normal, pay attention to the assembly height of air gap between the
coil assembly and magnet shaft, and refer to the geometric tolerance between the
assembly parts to make sure the coil assembly and the magnet shaft make no contact.
