WARNING
All wiring work must be carried out by a qualified electrician.
Wait at least 10 minutes after turning the power OFF, before starting wiring or inspections.
Failure to observe this could lead to electric shocks.
Install the servo amplifier and linear servomotor before staring wiring. Failure to observe this
could lead to electric shocks.
Do not damage, apply forcible stress, place heavy things on, or catch the cables. Failure to
observe this could lead to electric shocks.
CAUTION
Correctly wire the machine. Failure to observe this could lead to runaway of the linear
servomotor or injuries.
Make sure not to mistake the connection terminals. Failure to observe this could lead to
ruptures or trouble.
Make sure not to mistake the polarity (+, –). Failure to observe this could lead to ruptures or
trouble.
Make sure not to mistake the orientation of the surge absorbing diode installed on the DC
relay for the control output signal. Failure to do so could cause a trouble preventing the signal
from being output, or could inhibit operation of the protection circuit during an emergency
stop, etc.
Do not install a phase-advancing capacitor, surge absorber or radio noise filter on the output
side of the servo amplifier.
Shut off the power with the error signal. Failure to do so could cause the regenerative resistor
to abnormally overheat and fires to occur due to faults in the regenerative transistor, etc.
Do not modify the machine.
