User Manual of EM760 High-Performance Inverter * When the rated power of the inverter is greater than that ofthe motor, the motor parameters must be entered accurately to prevent the motor from damage as a result of overload. The technical specifications of the EM760 series inverter are shown below. Table 1-2 Technical Specifications for EM760 Inverter Series 15 Item Specification Power supply Rated voltage of power supply Three-phase 340V-10%~460V+10% (three-phase 380V) Three-phase 520V-15%~690V+10% (three-phase 660V) 50-60Hz ±5%; voltage unbalance rate: Output Maximum output voltage The maximum output voltage is the same as the input power voltage.
Rated output current Continuous output of 100% rated current Maximum overload current G model: 150% rated current for 60s P model: 120% rated current for 60s (2kHz carrier; please derate for carriers above this level) Basic control functions Driving mode V/F control (VVF) Speed sensorless vector control (SVC); Speed sensor vector control (FVC) Input mode Frequency (speed) input, torque input Start and stop control mode Keyboard, control terminal (two-line control and three-line control), communication Frequency control range 0.00~600.00Hz/0.0~3000.0Hz Input frequency resolution Digital input: 0.01Hz Analog input:
0.1% ofmaximum frequency Speed control range 1:50 (VVF), 1:200 (SVC), 1:1000 (FVC) Speed control accuracy ±0.5% (VVF), ±0.2% (SVC), ±0.02% (FVC) Acceleration and deceleration time 0.01 s to 600.00 s / 0.1 s to 6,000.0 s / 1 s to 60,000 s Voltage/frequency characteristics Rated output voltage: 20% to 100%, adjustable; fundamental frequency: 1Hz to 600Hz/3000Hz, adjustable Torque boost Fixed torque boost curve, any V/F curve optional Starting torque 150%/3Hz (VVF), 150%/0.25Hz (SVC), 180%/0Hz (FVC) Torque control accuracy ±5% rated torque (SVC), ±3% rated torque (FVC) Self-adjustment of output voltage When the input voltage changes, the output voltage will basically remain unchanged.
Automatic current limit Output current is automatically limited to avoid frequent overcurrent trips. DC braking Braking frequency: 0.01 to maximum frequency Braking time: 0~30S Braking current: 0% to 150% rated current Signal input source Communication, multi-speed, analog, high-speed pulse, etc.
