Slip Compensation - Mitsubishi Electric 800 Series Instruction Manual

6.3.7

Slip compensation

When Pr.407 Motor temperature detection filter  "9999", slip compensation is enabled under vector control for the motor
with an encoder. The slip frequency is compensated by Pr.326 Motor temperature feedback reference and the detected
temperature.
When using the motor constant set by offline auto tuning or set directly, set in Pr.326 the motor temperature for when the motor
constant (R2) was determined.
