S3800E Series Closed-loop vector control - High performance: Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology.
Overload capacity 60s for 150% of the rated current, 3s for 180%( 120%) of the rated current.
Ramp mode: Straight-line ramp; S-curve ramp; Four groups of acceleration/deceleration time with the range of 0.0-6500.0s
Item S3800E Based functions Control mode V/F(Voltage/Frequency) control Sensorless flux vector control (VC) Closed-loop vector control (CVC) Maximum frequency Vector control: 0-320 Hz V/F control: 0-3200Hz Carrier frequency 1.0-16.0 kHz The carrier frequency is automatically adjusted based on the load features. Input frequency esolution Dgital setting: 0.01 Hz Analog setting: 0.025% of maximum frequency Startup torque G type: 0.5 Hz/150% (VC); 0 Hz/180% (CVC) P type: 0.5 Hz/100% Speed range 1:100 (VC) 1:1000 (CVC) Speed stability accuracy ± 0.2% (VC) ± 0.02% (CVC) Torque control accuracy ± 5% (CVC) Overload capacity G type: 60s for 150% of the rated current, 3s for 180% of the rated current. P type: 60s for 120% of the rated current, 3s for 150% of the rated current. Torque boost Auto boost Customized boost 0.1%-30.0% V/F curve Line V/F curve Multi-point V/F curve N-power V/F curve (1.2-power, 1.4-power, 1.6-power,1.8-power, square) V/F separation two types: complete separation; half separation Ramp mode Straight-line ramp S-curve ramp Four groups of acceleration/deceleration time with the range of 0.0-6500.0s DC braking DC braking frequency: 0.00 Hz to maximum frequency Braking time: 0.0-100.0s Braking action current value: 0.0%-100.0% JOG control JOG frequency range: 0.00-50.00 Hz JOG acceleration/deceleration time: 0.0-6500.0s Onboard multiple preset speeds It implements up to 16 speeds via the simple PLC function or combination of terminal states Onboard PID It realizes process-controlled closed loop control system easily. Auto voltage It can keep constant output voltage automatically when the mains voltage changes. regulation (AVR) Overvoltage/ Overcurrent stall control The current and voltage are limited automatically during the running process so as to avoid frequent tripping due to overvoltage/over current. Torque limit and control It can limit the torque automatically and prevent frequent over current tripping during the running process.Torque control can be implemented in the CVC mode. Individualized functions Support for multiple PG card Support for rotating transformer PG card,differential input PG card, UVW differential input PG card, resolver PG card and OC input PG card Power dip ride through The load feedback energy compensates the voltage reduction so that the AC drive can continue to run for a short time. Rapid current limit It helps to avoid frequent over current faults of the AC drive. High performance Control of asynchronous motor and synchronous motor are implemented through the high-performance current vector control technology. Timing control Time range: 0.0-6500.0 minutes Communication methods MODBUS-RTU,PROFIBUS-DP,CAN Protection mode Motor short-circuit detection at power-on, input/output phase loss protection, over current protection, overvoltage protection, under voltage protection, overheat protection and overload protection. Input and output Input terminal 8 digital input terminals, one of which supports up to 100 kHz high-speed pulse input. 2 analog input terminals, one of which only supports 0-10 V voltage input and the other supports 0-10 V voltage input or 4-20 mA current input.
