User Manual of A90 Series Inverter Chapter 7 Function Code Details 7.1 Basic Function Parameter Group of F00 Group F00.01=0: V/F control (VVF) It is used for one-to-many, fast and low-precision speed control. F00.01=1: speed sensorless vector control (SVC) The open-loop vector control is suitable for general high-performance control. An inverter drives one motor only of the loads, e.g. machine tools, centrifuges, drawing machines, and injection molding machines. 1. In order to improve the control performance, self-learning is needed to obtain the correct motor parameters before vector control. 2.
In the vector control mode, the inverter can be used with one motor only, and the motor capacity should not be greatly different from the inverter capacity; otherwise, the control performance may decline or the system may not work properly. F00.02=0: keyboard control (LOC/REM indicator ON) The start and stop of the inverter are controlled by the RUN key RUN , STOP key and multi-function key M.K on the keyboard. In the case of no fault, press the multi-function key M.K to enter the jog running status, and the RUN key RUN to enter the running status.
If the green LED indicator above the RUN key RUN is normally 114 Function Function code Default Parameter description Unit Attribute code name setting F00.01 Drive control mode of motor 1 0: V/F control (VVF) 1: Speed sensorless vector control (SVC) 0 ○ Function Function code Default Parameter description Unit Attribute code name setting F00.02 Options of command source 0: keyboard control (LOC/REM indicator: ON) 1: terminal control (LOC/REM indicator: OFF) 2: communication control (LOC/REM indicator: flicker) 0 ○ STOP RESET
