Chapter 1. Checking and Handling
1-2
1.2 Caution during Use
Improper handling of the drive may lead to unexpected accident or damage. The following are
important points in drive operation.
1.2.1 Handling
y
Avoid impact to the encoder, the motor detector.
Striking the shaft with a hammer or dropping the motor may cause unexpected damage.
y
Do not connect commercial power supply (AC 220V) directly to the motor.
Direct connection induces flow of over current leading to demagnetize the magnet in motor.
Always use motor with specified servo drive.
1.2.2 Wiring
y
Connect the drive and the motor earth terminals in the direction of the drive, and ground the
terminals at the shortest distance at a time. To prevent both electric shock and improper
operation, use class-3 earth (Less than 100
Ω
).
y
Always match the U, V, W and FG terminals of the motor with those of the drive. You cannot
change the direction of rotation by changing 2 wires the same as in the case of widely used
general motors.
y
Connecting commercial power supply to the U, V ,W and FG terminals of the drive may cause
damage.
(Apply 200V power supply to R, S and T terminals)
Use a transformer in case power supply is other than 200V.
y
Connect standard regenerative resistor to the P and B terminals of the drive.
