1. Overview 1-9
Starting Torque 150%/3Hz
Motor Overload
Motor stops in 1 minute at approx. 150% of
motor rated current.
Instantaneous
Overcurrent
Motor stops immediately at 200% of inverter
rated current.
Inverter Overload
Motor coasts to stop in 1 minute at approx.
150% of inverter rated current.
Overvoltage Motor stops at 410V or higher.
Undervoltage Motor stops at 190V or lower.
Cooling Fin
Overheat
Motor stops if the temperature of the cooling
fin is higher than approximately 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).

*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 for 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.
