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.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands
and parts (cables, etc.) with the servo amplifier heat sink, regenerative brake
resistor, servo motor, etc. since they may be hot while power is on or for some time
after power-off. Their temperatures may be high and you may get burnt or a parts
may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can
cause injury.
