digitalen AC-Servosysteme

ZY-A900 series of AC drives is our newest product of sensorless vector control type. The system function is enriched and advanced vector control core is adopted. With the high utilization rate of voltage, the high power factor, the fast dynamic response, high precision, and low noise. ZY-A900 series can meet wide-ranging application. Characteristic. Auto torque promotion and auto slip compensation realizes larger output torque at low frequency.. User-defined curve, V/F curve can be adjusted.. Lower-noise, carrier-wave frequency can be adjusted from 2KHZ to 10KHZ.. Control protection is immediate and reliable, which improves system stability.. Built-in filter is optional. Compatible with NPN and PNP types.. Advanced vector control technology realizes more precise control and more excellent performance.. Torque is elevated automatically, starting torque reaches 150% at 0.5Hz, and torque control precision reach ±5%.. Output frequency is 0.50-200Hz. The highest resolution is 0.01Hz.ZY-A900 Technical SpecificationsItemsContentsInputRated Voltage Range3-phase 400V±15%; single-phase 230V±15%Rated Frequency50/60HzOutputRated Voltage Range3-phase 0 400V;3-phase 0 230VFrequency Range0.50 200.0HzControlModeCarrier Frequency2K 10KHz;Input Frequency ResolutionDigital setting: 0.01Hz, analog setting: max frequency 0.1%Control ModeV/F control and SVC controlOverload Capacity150% rated current, 60 seconds.Torque ElevatingAuto torque promotion, Manual Torque Promotion 0.1% 30.0% (VVVF), 0.5Hz/150% (SVC)V/F Curve4 kinds of modes: beeline type, square type, under-defined V/F curve and auto torque compensation. .DC BrakingDC braking frequency: 1.0 5.0 Hz, braking time: 0.0 10.0sJogging ControlJogging frequency range: min frequency max frequency, jogging acceleration/deceleration time: 0.1 3000.0sAuto Circulating Running and multi-stage speed runningAuto circulating running or terminals control can realize 15-stage speed running.Built-in PID adjustingEasy to realize a system for process closed-loop controlOperation FunctionFrequency SettingPotentiometer or external analog signal (0 5V, 0 10V, 0 20mA); keypad (terminal) keys, external control logic and automatic circulation setting.Start/Stop ControlTerminal control, keypad control MODBUS control.Running Command Channels3 kinds of channels from keypad panel, control terminal and MODBUS.Frequency Sourcegiven digit, given analog voltage, given analog current, given pulse frequency, given MODBUS, PID adjusting and stage-speed control.Accessorial frequency Sourcegiven digit, given analog voltage, given analog current, PID adjusting and stage-speed control.OptionalBuilt-in EMI filter, built-in braking unit, tele-control panelProtection FunctionInput out-phase, input under-voltage, DC over-voltage, over-current, over-load, current stall, over-heat, external disturbanceDisplayLED nixie tube showing present output frequency, present rotate-speed (rpm), present output current, present output voltage, present linear-velocity, types of faults, and parameters for the system and operation; LED indicators showing the current working status of inverter.Environment ConditionsEquipment LocationIn an indoor location, Prevent exposure from direct sunlight, Free from dust, tangy caustic gases, flammable gases, steam or the salt-contented, etc.Environment Temperature-10degree celsius +50degree celsiusEnvironment HumidityBelow 90% (no water-bead coagulation)Vibration StrengthBelow 0.5g (acceleration)Height above sea level1000m or belowApplicable Motor0.2 220KW
