EM600 High-Performance Vector Control Inverter User Manual external terminal or communication. Autotuning status: Set through keypad to autotune parameters of motor in stationary or rotational autotuning. Stop status: When running command is inactive, output frequency drops to zero as per set deceleration time. JOG stop status: When JOG running command is inactive, output frequency drops to zero as per JOG deceleration time. Fault status: Refer to status of inverter at all kinds of faults. 1.2.2 Control Modes of Inverter Control modes of inverter refer to what kind of open loop or closed loop method is adopted to drive motor at desired speed or torque. These modes include:
General open loop space vector control – V/F control: Suitable for low speed change and low speed stability accuracy and meet the needs of most AC motor drives. Sensorless vector control (SVC): Advanced speed estimation method, no encoder required, closed loop vector control and high control accuracy. Feedback Vector Control (FVC): Speed and current are under real-time closed-loop control with high stability speed accuracy and high dynamic response. An encoder must be added under this control mode. 1.2.3 Setting Modes of inverter Stting mode of inverter refers to what kind of physical quantity is taken as the control object when inverter drives a motor. Speed setting mode:
Motor speed is taken as the control object; Can be realized by numeric setting, analog quantity input setting, high-speed pulse input setting, communication setting, process PID, simple PLC or preset speed, individually or jointly. In Figure 1-1 to Figure 1-4, various input modes under speed setting mode of EM600 are described: 辅助频率源B给定 Main frequency source 主频率源A给定 Auxiliary frequency A setting 0：主辅通道合成频率 0: Synthetic frequency of main 0 1 主辅运算给定 Main and auxiliary arithmetic setting source B setting 主辅 通道 合成 频率 增益 F00.12 0 1 1：AI1*主辅通道合成频率 1:
