WARNING Do not operate the switches with wet hands. You may get an electric shock.
CAUTION
Before starting operation, check the parameters. Some machines may perform
unexpected operation.
During power-on or soon after power-off, do not touch the servo amplifier heat
sink, regenerative brake resistor, servo motor, etc. as they may be at high
temperatures. You may get burnt.
Connect the servo motor with a machine after confirming that the servo motor operates properly alone.
For startup reference, a single machine structure will be described. Refer to this section and start up the
machine safely.
