Protection
Functions
Power Supply Regeneration Available
Motor Protection Electronic thermal overload relay
Momentary Overcurrent
Protection
Drive stops when output current reaches about 200% of the rated current.
Overload Protection
Overload protection may be triggered when operating with 150% of the rated output current if the output
frequency is less than 6 Hz.
Overvoltage Protection
200 V class: Stops when input voltage exceeds approximately 315 V
400 V class: Stops when input voltage exceeds approximately 630 V
Undervoltage Protection
200 V class: Stops when input voltage falls below approximately 150 V
400 V class: Stops when input voltage falls below approximately 300 V
Momentary Motor Power
