4 Start-up and trial operation

DANGER:

● Be sure to ground the Motion controllers, servo amplifiers and servomotors (Ground

resistance: 100 Ω or less). Do not ground commonly with other devices.

● Never open the front case or terminal cover at times other than wiring work or periodic

inspections even if the power is OFF. The insides of the Motion controller and servo amplifier

are charged and may lead to electric shocks.

● When performing wiring work or inspections, turn the power OFF, wait at least ten minutes,

and then check the voltage with a tester, etc. Failing to do so may lead to electric shocks.

● Wire the units after mounting the Motion controller, servo amplifier and servomotor. Failing

to do so may lead to electric shocks or damage.

WARNING:

● Check that the combination of modules are correct. Wrong combination may damage the

modules.

● When using a regenerative resistor, shut the power OFF with an error signal. The regenera-

tive resistor may abnormally overheat due to a fault in the regenerative transistor, etc. and

may lead to fires.

● Always take heat measure such as flame proofing for the inside of the control panel where

the servo amplifier or regenerative resistor is mounted and for the wires used. Failing to do

so may lead to fires.

● Do not mount a phase advancing capacitor, surge absorber or radio noise filter (option

FR-BIF) on the output side of the servo amplifier.

● Correctly connect the output side (terminal U, V, W). Incorrect connections will lead the servo

motor to operate abnormally.

● Set parameter values to those that are compatible with the Motion controller, servo ampli-

fier, servo motor and regenerative resistor model name and the system name application.

The protective functions may not function if the settings are incorrect.

● Always mount a leakage breaker on the Motion controller and servo amplifier power source.

● Install emergency stop circuit externally so that operation can be stopped immediately and

the power shut off.

● Use the program commands for the program with the conditions specified in the instruction

manual.

● Some devices used in the program have fixed applications, so use these with the conditions

specified in the programming manual.

● If safety standards (ex., robot safety rules, etc.,) apply to the system using the Motion

controller, servo amplifier and servo motor, make sure that the safety standards are satis-

fied.

● Construct a safety circuit externally of the Motion controller or servo amplifier if the abnor-

mal operation of the Motion controller or servo amplifier differ from the safety directive

operation in the system.

● The system must have a mechanical allowance so that the machine itself can stop even if the

stroke limits switch is passed through at the max. speed.

● Execute the test operation in the system that it is low-speed as much as possible and put

forced stop and confirm the operation and safety.
