Electronic thermal overload protection
Motor Protection
Drive stops when the output current is more than 200% of the HD output current.
Momentary
Overcurrent Note:
Protection
Standard value is 200%. Different capacity drives have different values.
Drive stops when the output current is more than these overload tolerances:
• HD: 150% of the rated output current for 60 seconds. The permitted frequency of overload is once every 10 minutes.
Overload Protection
• ND: 110% of the rated output current for 60 seconds. The permitted frequency of overload is once every 10 minutes.
Note:
If output frequency < 6 Hz, the drive can trigger the overload protection function when the output current is in the overload tolerance range.
Overvoltage 200 V class: Stops when the DC bus voltage is more than approximately 410 V
Protection
400 V class: Stops when the DC bus voltage is more than approximately 820 V
Three-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately 190 V
Undervoltage
Single-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately 160 V
Protection
Three-phase 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 and continues operation if power loss is shorter than 2 s (depending on parameter settings).
Note:
Momentary Power
• Stop time may be shortened depending on the load and motor speed.
Loss Ride-thru
• 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 2001 to 2042 and 4001 to 4023.
Heatsink Overheat
Thermistor
Protection
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.
