10.5 Common Drive Specifications
YASKAWA SIEPC71061737B GA800 Drive Technical Reference 441
Item Specification
Undervoltage
Protection
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
Momentary Power
Loss Ride-thru
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
power loss on models 2004 to 2056 and 4002 to 4031.
Heatsink Overheat
Protection
Thermistor
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
•
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.
Braking Transistor Built-in to models 2004 to 2138 and 4002 to 4168
DC Link Choke
Built-in to models 2110 to 2415 and 4060 to 4720
