CAUTION
z
Install the encoder cables in a separate conduit from the motor power cables to
avoid signal noise. Separate the conduits by 30cm.
z
As a charge may still remain in the drive with hazardous voltages even after power
has been removed, be sure to wait at least 10 minutes after power has been
removed before performing any wiring and/or inspection.
z
It is not recommended to frequently power the drive on and off. Do not turn the drive
off and on more than once per minute as high charging currents within the internal
capacitors may cause damage.
Main Circuit Terminal Wiring
CAUTION
z
Remove the terminal block from the servo drive before wiring.
z
Insert only one wire into one terminal on the terminal block.
z
When inserting wires ensure that the conductors are not shorted to adjacent
terminals or wires.
Trial Run without Load
CAUTION
z
In order to prevent accidents, the trial run for servo motor should be conducted
under no load condition (run the servo motor alone without connecting couplings
and belts).
z
For the initial trial run, do not operate the servo motor while it is connected to the
mechanical system. Connecting the motor to its mechanical system may cause
damage during the trail run. Connect the servo motor once it has successfully
completed a trail run.
Trial Run with Load
CAUTION
z
After the trial run without load is completed, conduct a second trial run with load.
