Drive stops when the output current is more than 200% of the HD output current.
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 one time each 10 minutes.
• ND: 110% of the rated output current for 60 seconds The permitted frequency of overload is one time each 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.
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
200 V class: Stops when the DC bus voltage decreases to less than approximately 190 V
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).
Note:
• 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

Precautions during Wiring
• Use terminals B1 and - to connect braking units to drives that have built-in braking transistors (models 2004 to

• Refer to “Yaskawa AC Drive Option Braking Unit, Braking Resistor Unit Instruction Manual (TOBPC72060001)”
for information about wire gauges and tightening torques to connect braking resistor units or braking units.
• Use terminals +1 and - to connect a regenerative converter or regenerative unit.
Fire Hazard. Do not connect a braking resistor to terminals +1 or -. Use terminals B1 and B2 for the braking
resistor connections. If you connect a braking resistor to the incorrect terminals, it can cause damage to the drive and braking circuit
and serious injury or death.
Wire Gauge and Torque Specifications for UL Listing
Refer to Three-Phase 200 V Class on page 27 and Three-Phase 400 V Class on page 31 for the recommended wire
gauges and tightening torques of the main circuit terminals.
Note:
• The recommended wire gauges are based on drive continuous current ratings with 75 °C (167 °F) 600 V class 2 heat-resistant indoor PVC
wire. Assume these conditions:
–Ambient temperature: 40 °C (104 °F) or lower
–Wiring distance: 100 m (328 ft) or shorter
–Normal Duty Rated current value
• Use terminals +1, +2, +3, -, B1, and B2 to connect a peripheral option such as a DC link choke or a braking resistor. Do not connect other
items to these terminals.
• Refer to the instruction manual for each device for recommended wire gauges to connect peripheral devices or options to terminals +1, +2,
+3, -, B1, and B2. Contact Yaskawa or your nearest sales representative if the recommended wire gauges for the peripheral devices or
options are out of the range of the applicable gauges for the drive.
