Yaskawa GA500 Series AC Inverter for 18.5kW (25HP) 400V 3ph motor to 39A at high overload or 22kW (30HP) to 44A 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 7b: 190mm Wide x 251mm Deep x 350mm High. IP20.
Weight: 8kg.
18.5kW; 39A with 150% overload for 60 seconds. - Heavy Duty (HD). (Once every 10 minutes) - Default Setting
22kW; 44A 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.
