4. TRIAL RUN AND ADJUSTMENT
Check and adjust the programs and parameters before starting trial operation. Errors in the
programs or parameters may cause the machine to make unpredicted movements.
Never make very large adjustments as this can make operation unstable.
Do not open the front casing or terminal cover during operation or when power is connected.
This can cause electric shocks.
Do not operate with the front case or terminal cover open. This can cause electric shocks from
exposed high-Voltage terminals or charged parts.
Do not operate switches when your hands are wet. This can cause electric shocks.
Do not scratch, apply undue strain to, place heavy weights on, or trap, cables. This can cause
electric shocks.
Do not touch controller, servo-amplifier, or servomotor terminal blocks while power is turned on.
This can cause electric shocks.
Do not touch the controller or servo amplifier internal power supply, internal ground, or signal
wires. This can cause electric shocks.
The machine may make unpredicted movements after a servo amplifier or servomotor is turned
on. Top prevent accidents, check the operation of each individual motor.
Start up servos according to the servo start-up procedure described below.
The servo amplifier cooling fins, regenerative resistor, and servomotors become hot during
operation and can remain hot for some time after power is turned off. Do not touch these parts or
burn injuries may result.
To avoid injury, turn off the power before touching servomotor shafts or machinery connected to
them.
To avoid injury, do not approach machinery during trial or teaching operation.
