User Manual of EM730 Series Inverter codes are defined the same as those in the first group. The function codes F14.00 to F14.34 correspond to F01.00 to F01.34, which are motor nameplate parameters, motor parameters and encoder parameters; the function code F14.35 corresponds to F00.01, which is used to select the motor drive mode; the function codes F14.36 to F14.76 correspond to F06.00 to F06.40, which are vector control parameters; and the function code F14.77 is used to select the acceleration/deceleration time of the motor 2. Only the parameters of F14.72 are described below. For the rest of the parameters, refer to the relevant parameters of the motor 1.
changing the speed proportional gain (ASR_P) and speed integral time (ASR_T) of the speed PI In the vector control mode, the dynamic speed response of the inverter is adjusted by regulator. The increase in ASR_P or decrease in ASR_T may accelerate the dynamic response of the speed loop. If ASR_P is too large or ASR_T is too small, however, the system may be over-tuned to cause oscillation. accordingly. The regulation intensity of the PI regulator for the speed of the motor 2 can be In case of any change in F14.52, the default settings of F14.36-F14.39 will change adjusted. There are 21 groups of parameters in total.
The larger the set value of F14.52, the smaller the integral time is, and the more intense the speed PID regulation is. The smaller the set value of F14.52, the weaker the speed PID regulation is. 271 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F14.52 Stiffness coefficient of speed loop of motor 2 0~20 12 ● 0x0E34 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F14.77 Acceleration/deceler ation time options of motor 2 0: the same as motor 1 1: acceleration and deceleration time 1 2: acceleration and deceleration time 2 3: acceleration and deceleration time 3 4:
