User Manual EM303B General Purpose Inverter F5-22=1 Negative torque prohibited. F5-13 and F5-23 will be blocked. F5-22=0 Negative torque permitted. F5-13 defines the torque output direction. F5-23 is for setting the transit time at zero output torque for the inverter in the process of switching positive and negative torque. See Figure 7-19. Output Torque Time Deadband The torque direction refers to the setting direction of torque current, but not the rotational direction of motor. Time Figure 7-19 Deadband of Positive/Negative Torque 1. The default forward direction of motor is the positive torque direction. 2.
If positive/negative torque switching is applied in torque program operation mode, it cannot be switched by terminals. F5-24 and F5-25 are PID regulator parameters of torque current, and will affect system performance and stability directly. User does not need to change the defaults on general conditions. F5-27 is for the control mode of inverter output frequency near zero frequency. F5-27=0 Brake current at zero frequency can be set by F7-31, and it will make motor not be driven by the load when the output frequency of inverter is zero frequency. F5-27=1 Normal output control. F5-27=2 There is no output near zero frequency. Motor can rotate freely. 120 No.
