User Manual of EM730 Series Inverter negative, the upper frequency limit corresponding to the forward speed limit is AI1 (percentage) * F13.09 * F13.18 and that corresponding to the reverse speed limit is AI1 (percentage) * F13.09. Maximum operating frequency in torque control = upper frequency limit of torque control + offset of upper frequency limit (valid only when F13.08=1 to 5), but the maximum operating frequency is limited by the maximum frequency of F00.16. When the motor drives an object to move, it is necessary to overcome static/dynamic friction.
You can set this group of parameters to enable the motor rotation at the specified torque while overcoming the inherent static/dynamic friction. The motor is mainly subject to static friction before rotation and dynamic friction after starting rotating. In short, the output performance of the motor is related to this group of parameters. The specific description of this group of parameters is as follows:
“when the actual frequency (estimate frequency in SVC) is less than or equal to the set value of F13.12, the output torque is the ‘set torque + F13.11 static friction torque compensation’; and when the actual frequency is greater than the set value of F13.12, the output torque is ‘set torque + F13.13 dynamic friction torque compensation’”. The larger the compensation value, the stronger the compensation force will be. The compensation percentage is equal to the torque setting percentage. 7.15 Parameter Group of Motor 2 of F14 group motor nameplate parameters, encoder parameters and VF control or vector control parameters The two motors of the EM730 series inverter can be switched.
For the two motors, the can be set separately, and the VF control or vector control can be selected independently. In addition, the parameters of the two motors can be tuned separately. All motor parameters in the second group are included in the F14 group, and the function 270 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F13.11 Static friction torque compensation 0.0 ~100.0 % 0.0 ● 0x0D0B F13.12 Frequency range of static friction compensation 0.00 ~ 50.00 Hz 1.00 ● 0x0D0C F13.13 Dynamic friction torque compensation 0.0 ~ 100.0 % 0.0 ● 0x0D0D
