Item Specification
Motor Protection
Electronic thermal overload protection
Momentary
Overcurrent
Protection
Drive stops when the output current is more than 200% of the HD output current.
Overload Protection
Drive stops when the output current is more than these overload tolerances:
• HD: 150% of the rated output current for 60 seconds.
• ND: 110% of the rated output current for 60 seconds.
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
Protection
200 V Class: Stops when the DC bus voltage is more than approximately 410 V
400 V Class: Stops when the DC bus voltage is more than approximately 820 V
Undervoltage
Protection
Single-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately 160 V
Three-phase 200 V class: Stops when the DC bus voltage decreases to less than approximately 190 V
Three-phase 400 V class: Stops when the DC bus voltage decreases to less than approximately 380 V
Momentary Power
Loss Ride-thru
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:
• Load size and motor speed can cause the stop time to be shorter.
• 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
Protection
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 drive models.
Braking Resistor
Overheat Protection
Overheat detection for braking resistor (optional ERF-type, 3% ED)
Stall Prevention
Stall prevention is available during acceleration, deceleration, and during run.
Ground Fault
Protection
Electronic circuit protection
Note:
This protection detects ground faults during run. The drive will not provide protection when:
• There is a low-resistance ground fault for the motor cable or terminal block
• There is a ground fault and you energize the drive
DC Bus Charge LED
Charge LED illuminates when DC bus voltage is more than 50 V.

Ambient
Temperature
IP20/UL Open Type: -10 °C to +50 °C (14 °F to 122 °F)
IP20/UL Type 1: -10 °C to +40 °C (14 °F to 104 °F)
• When you install the drive in an enclosure, use a cooling fan or air conditioner to keep the internal air temperature in the permitted range.
• Do not let the drive freeze.
Humidity
95% RH or less
Do not let condensation form on the drive.
Storage Temperature
-20 °C to +70 °C (-4 °F to +158 °F) (short-term temperature during transportation)
Surrounding Area
Pollution degree 2 or less
Install the drive in an area without:
• Oil mist, corrosive or flammable gas, or dust
• Metal powder, oil, water, or other unwanted materials
• Radioactive materials or flammable materials, including wood
• Harmful gas or fluids
• Salt
• Direct sunlight
