Yaskawa GA500 Series AC Inverter for 15kW (20HP) 400V 3ph motor to 31A at high overload or 18.5kW (25HP) to 38A when Fan/Pump rated. Operates in VxF or Sensorless Vector and converts fixed frequency Three Phase 400V input to variable frequency Three Phase 400V to control a standard AC induction, permanent magnet or synchronous reluctance motor.
Size 6b: 180mm Wide x 196mm Deep x 300mm High. IP20.
Weight: 5.5kg.
15kW; 31A with 150% overload for 60 seconds. - Heavy Duty (HD). (Once every 10 minutes) - Default Setting
18.5kW; 38A with 110% overload for 60 seconds. Normal Duty (ND). (Once every 10 minutes) - Change paramenter C6-01 to 1 for ND Rating
Speed Control Range: 0-590Hz.
Braking (DBr): Built-in braking transistor for 100% Torque for 10 seconds every 100 seconds (10% duty cycle). A 20 Ohm minimum external resistor is required for Dynamic Braking. Resistor is not supplied and should only be fitted if this feature is required.
