Operation Of Digital Operator
• Never touch the heat sink; the temperature is very high. Failure to observe this cau-
tion 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
caution can result in personal injury.
• Do not check signals during operation. The machine or the unit may be damaged.
• All the constants of the inverter have been preset at the factory. Do not change the
settings unnecessarily. The machine or the unit may be damaged.
• Disconnect all power before removing digital operator (JVOP-132). Then wait for the
time described on warning labels after main circuit power supply and control power
supply are disconnected and all LEDs of the inverter and the converter are extin-
guished. Failure to observe this warning can result in an electric shock.
