4. OPERATION

4.1.2 Startup

WARNING Do not operate the switches with wet hands. You may get an electric shock.

Before starting operation, check the parameters. Some machines may perform unexpected operation.

CAUTION 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.
