WARNING
1. Electric shock prevention
Do not open the front cover while the power is ON or during operation. Failure to observe this could lead
to electric shocks.
Do not operate the unit with the front cover removed. The high voltage terminals and charged sections
will be exposed, and can cause electric shocks.
Do not remove the front cover and connector even when the power is OFF unless carrying out wiring
work or periodic inspections. The inside of the units is charged, and can cause electric shocks.
Since the high voltage is supplied to the main circuit connector while the power is ON or during
operation, do not touch the main circuit connector with an adjustment screwdriver or the pen tip. Failure
to observe this could lead to electric shocks.
Wait at least 15 minutes after turning the power OFF, confirm that the CHARGE lamp has gone out, and
check the voltage between P and N terminals with a tester, etc., before starting wiring, maintenance or
inspections. Failure to observe this could lead to electric shocks.
Ground the unit and motor following the standards set forth by each country.
Wiring, maintenance and inspection work must be done by a qualified technician.
Wire the servo drive unit and servomotor after installation. Failure to observe this could lead to electric
shocks.
Do not touch the switches with wet hands. Failure to observe this could lead to electric shocks.
Do not damage, apply forcible stress, place heavy items on the cables or get them caught. Failure to
observe this could lead to electric shocks.
After assembling the built-in IPM spindle motor, if the rotor is rotated by hand etc., voltage occurs
between the terminals of lead. Take care not to get electric shocks.
