Item
200 V Class: Stops when the DC bus voltage is more than approximately 410 V
Overvoltage
Protection
400 V Class: Stops when the DC bus voltage is more than approximately 820 V
200 V Class: Stops when the DC bus voltage decreases to less than approximately 190 V
Undervoltage
Protection
400 V Class: Stops when the DC bus voltage decreases to less than approximately 380 V
Stops when power loss is longer than 15 ms.
Continues operation if power loss is shorter than 2 s (depending on parameter settings).
Momentary Power
Note:
Loss Ride-thru
• Stop time may be shortened depending on the load and motor speed.
• Drive capacity will change the continuous operation time. A Momentary Power Loss Recovery Unit is necessary to continue operation through a 2 s
power loss on models 2004 to 2056 and 4002 to 4031.
Heatsink Overheat
The drive stops when the thermistor detects an IGBT temperature more than approximately 100 °C (212 °F). The trip temperature level is different for different
Protection
drive models.
Braking Resistor Overheat detection for braking resistor (optional ERF-type, 3% ED)
Overheat Protection
Stall prevention is available during acceleration, deceleration, and during run.
Stall Prevention
Electronic circuit protection
Note:
Ground Fault
This protection detects ground faults during run. The drive will not provide protection when:
Protection
• There is a low-resistance ground fault for the motor cable or terminal block
• Energizing the drive when there is a ground fault.
DC Bus Charge LED Charge LED illuminates when DC bus voltage is more than 50 V.
Models 2004 to 2138 and 4002 to 4168 have a braking transistor.
Braking Transistor
Models 2110 to 2415 and 4060 to 4720 have a DC link choke.
