WARNING
Only turn ON the input power supply after replacing the front cover. Do not remove the cover while current is flowing. Failure to
observe this can result in an electrical shock.
When the retry function (n057) is selected, do not approach the Inverter or the load, since it may restart suddenly after being
stopped. (Construct machine system, so as to assure safety for personnel, even if the Inverter should restart.) Failure to observe
this can result in personal injury.
Since the stop button can be disabled by a function setting, install a separate emergency stop switch. Failure to observe this can
result in personal injury.
CAUTION
Never touch the heatsink or discharging resistor since the temperature is very high. Failure to observe this can result in harmful
burns to the body.
Since it is easy to change operation speed from low to high speed, verify the safe working range of the motor and machine before
operation. Failure to observe this can result in personal injury and machine damage.
• Install a holding brake separately if necessary. Failure to observe this caution can result in personal injury.
• Do not change signals during operation. The machine or the Inverter may be damaged.
All the constants of the Inverter have been preset at the factory. Do not change the settings unnecessarily. The Inverter may be
damaged. For supply voltage, follow Paragraph 4.3 of Chapter 4.
