 2 Control Methods

Yaskawa drives support several control schemes depending on series

Vf Control VoltageFrequency Basic speed control mode

Openloop Vector Control Better torque  speed performance without encoder

Flux Vector Control Enhanced performance with or without sensors

Encoder Feedback On higher models for precision control A1000 and up

Typical control range

Openloop vector up to 1100 speed range

Vf 140 speed range

PM open loop 110 speed range

 3 Performance Characteristics

 Torque  Frequency

Starting Torque 150  at low frequency in many models can be higher on vector drives

Carrier Frequency Adjustable  can range from 2 kHz up to 15 kHz in some series

Speed Response Good response in vector modes several Hz feedback

 Protection  Builtin Safety

Protections Overcurrent overunder voltage overload overheating shortcircuit and more are standard on most Yaskawa drives

Braking Many models include builtin braking transistors some have optional braking resistors

Ambient Typically 10 C to 50 C without derating

 4 Communications  IO Typical

Digital and analog inputs for control and feedback number varies by model

Some models support RS485 Modbus and optional fieldbus modules can be added in advanced series

PC configuration tools and mobile apps available for setup on newer series like GA700
