CAUTION
The surge absorbing diode installed to the DC relay for control output should be fitted in the specified
direction. Otherwise, the emergency stop and other protective circuits may not operate.

When the cable is not tightened enough to the terminal block (connector), the cable or terminal block
(connector) may generate heat because of the poor contact. Be sure to tighten the cable with specified
torque.
(3) Test run adjustment
CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to perform
unexpected operation.
The parameter settings must not be changed excessively. Operation will be insatiable.
(4) Usage
CAUTION
Provide an external emergency stop circuit to ensure that operation can be stopped and power switched
off immediately.
Any person who is involved in disassembly and repair should be fully competent to do the work.
Before resetting an alarm, make sure that the run signal of the driver is off to prevent an accident. A
sudden restart is made if an alarm is reset with the run signal on.
Do not modify the equipment.
Use a noise filter, etc. to minimize the influence of electromagnetic interference, which may be caused by
electronic equipment used near the driver.
Burning or breaking a driver may cause a toxic gas. Do not burn or break a converter unit and driver.
Use the driver with the specified servo motor.
The lock 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 lock may not hold the motor shaft. To ensure safety, install a stopper on the
machine side.
