compensation

this becomes the gain to compensate for slip caused by motor temperature variation when motor,the temperature rise by converting it into slip compensation of inverter. its show inverters value.



SLIP COMPENSATION GAIN OF INVERTER

this function is used to improve speed accuracy when operating with a load .setting range is 0.0~2.5
and factory setting is 1.0 .its setting  very easy from parameters.

NOTE:

this constant dose not normally need to be set . with flux vector control, this becomes the gain to compensate for slip caused by motor temperature variation when motor temperature rises, the motors interior constants change and the slip compensation will be increased . set this constant and adjust the temperature rise by converting it into slip compensation .

this constant can be adjusted when the motors output torque changes at higher temperatures when torque control or limits are used . the larger the setting , the larger the compensation will be set this constant to be 1.0, to compensate the slip set according to rated torque output situation ,for flux vector control , it is used to be motors temperature compensation gain . the motor slip compensation function calculates the motor torque according to the output current and set gain to compensation for output frequency .

this function is used to improve speed accuracy when operating with a load . it is mainly effective with v/f control (without pg). when the control method is switched the factory setting changes as follows v/f control , 0.0, v/f with pg 1.0 open loop vector 0, flux vector 1.0 . when  1.0 is set this function compensation for the rated slip that has been set by the rated torque output .

with flux vector control this becomes the gain to compensate for slip caused by motor temperature variation ,(refer to slip compensation gain , c 3-0 1 under 7.3.6.)the adjustment consequence of slip compensation gain . 1 correctly set the motor rated slip (constant e 2-0 2)and the motor no load current (constant e 2-0 3). the motor rated slip can be calculated by means of the following equation using the numbers that are shown on the motor nameplate .

motor rated slip , motor rated frequency (Hz) rated speed (r/min )x motor (no. of poles )/120 set the values at the rated voltage and rated frequency for the motor no load current . with vector control the motor rated slip is automatically set by auto tuning, 2 set the slip compensation gain (constant c 3- 0 1 to 1.0  if it set to 0.0 slip compensation will be disable). operate with a load measure the speed and adjust the slip compensation gain (in increments of 0.1)when actual speed is low increase the set value when actual speed is high decrease the set value.

  1. I have been browsing on-line greater than 3 hours today, but I never
    discovered any fascinating article like yours. It’s beautiful worth enough
    for me. Personally, if all web owners and bloggers
    made good content as you did, the web might be a lot more useful
    than ever before.

  2. Nice post. I used to be checking continuously this blog and I am inspired!
    Very useful info specially the last phase 🙂 I take care of such information a
    lot. I was looking for this particular information for a very lengthy time.
    Thank you and best of luck.

  3. obviously like your website however you have to check the spelling on quite a few of your posts.
    Many of them are rife with spelling problems and I in finding it very troublesome to tell the truth nevertheless I will certainly come again again.

  4. I like the helpful information you provide in your articles.
    I will bookmark your blog and check again here frequently.
    I’m quite certain I’ll learn a lot of new stuff
    right here! Best of luck for the next!

  5. I’ve been exploring for a little for any high-quality articles or weblog posts
    in this kind of space . Exploring in Yahoo I eventually stumbled upon this site.
    Reading this information So i am satisfied to exhibit that I’ve an incredibly good uncanny feeling I discovered exactly what I needed.
    I such a lot no doubt will make sure to do not overlook this site and give it a glance on a
    constant basis.

  6. Oh my goodness! Amazing article dude! Thank you, However I am experiencing difficulties with your RSS.
    I don’t know why I can’t join it. Is there anyone else getting similar RSS
    issues? Anyone who knows the answer will you kindly respond?
    Thanx!!

  7. Thank you for another informative web site. Where else could I get that type of info written in such a perfect way? I have a project that I am just now working on, and I’ve been on the look out for such info.
