(2) Wiring 
 CAUTION 
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly. 
Do not install a power capacitor, surge killer, or radio noise filter (FR-BIF-(H) option) on the servo 
amplifier (converter unit) output side. 
To avoid a malfunction, connect the wires to the correct phase terminals (U, V, and W) of the servo 
amplifier (converter unit) and servo motor. 
Connect the servo amplifier (converter unit) power output (U, V, and W) to the servo motor power input 
(U, V, and W) directly. Do not let a magnetic contactor, etc. intervene. Otherwise, it may cause a 
malfunction.

Do not connect AC power supply directly to the servo motor. Otherwise, it may cause a malfunction.
 
When the cable is not tightened enough to the terminal block, the cable or terminal block may generate 
heat because of the poor contact. Be sure to tighten the cable with specified torque. 
 
(3) Test run and adjustment 
 CAUTION 
Before operation, check the parameter settings. Improper settings may cause some machines to operate 
unexpectedly. 
Never adjust or change the parameter values extremely as it will make operation unstable. 
 
(4) Usage 
 CAUTION 
Provide an external emergency stop circuit to ensure that operation can be stopped and power switched 
off immediately. 
Do not scratch the coated surface with hard objects nor clean the coated surface with an organic solvent. 
Doing so may scuff the surface. 
Do not disassemble, repair, or modify the equipment. 
Use the servo amplifier (converter unit) with the specified servo motor. 
The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be 
used for ordinary braking. 
For such reasons as service life and mechanical structure (e.g. where a ball screw and the servo motor 
are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety, 
install a stopper on the machine side.
