Chapter 3 – Function Settings 8) Operation-starting method Parameter Name Code Description Starting method FU2-20 FU2-21 FU2-26 FU2-27 Motor starting method: [FU2-20]: Power-on run, [FU2-21] Restart after Fault Reset, [FU2-26] Number of Auto Restart Attempt [FU2-27] Delay Time Before Auto Restart See parameter description for more details. Speed Search Selection FU2-22 FU2-23 FU2-24 FU2-25 Speed search function is available during Accel, trip, instant power failure, restart after fault reset and auto restart. See parameter description for more details. 3.1.3 Application function setting 1) PID operation The inverter can be used to exercise process control, e.g. flow rate, air volume or pressure via PID feedback control. Parameter Name Code PID control setting FU2-41~ FU2-60 Description Parameters for PID control setting 2) Jog and Multi-speed operation Parameter Name Code Multi function input terminal setting Filter time constant for input terminal I/O-12 ~14 EXT2 ~ 4 If I/O-12 ~14 are set to Speed-H, Speed-M, Speed-L, multi- speed operation up to speed 7 is available.
