1. Overview 1-11
Inverter Overload
Motor coasts to stop in 1 minute at approx.
150% of inverter rated current.
Overvoltage Motor stops at 820V or higher.
Undervoltage Motor stops at 380V or lower.
Cooling Fin
Overheat
Motor stops if the temperature of the
cooling fin is higher than 90℃.
Momentary Power Loss
Motor stops if power loss is 15ms or longer,
by selecting the momentary power loss
mode, operation can be continued if power
is restored within 500ms.
Stall Prevention
Automatic setting during acceleration,
deceleration, and constant speed operation
(individual setting is possible).
Power Charge
Indication
LED is ON until the DC bus voltage
becomes 50V or less.
Location
Indoor
(Free from corrosive gas, dust, or oil)

*1.
The maximum applicable motor capacity is for a standard 4-pole
motor. When selecting the motor and inverter, make sure that the
inverter’s rated current is applicable fro the motor’s rated current.
*2. Tuning may be required.
*3. The storage temperature refers to the temperature during the
transportation for a short period of time.
