E300 Drive – Need to run lift temporarily on Test Control without a Motor Encoder. PLEASE NOTE this can ONLY be carried out on GEARED/INDUCTION MOTORS and should not be used as a Permanent Magnet Gearless Machines.

  1. Change parameter C.14 from Feedback to Sensorless (Do Not Change The Control Mode To Open Loop A.02 or B.01).
  2. Change parameter C.21 Bit 0 (First Bit on Right) from 1 to 0. This will disable the Encoder Wire Break Detection. If left enabled the drive will report an Encoder 2 trip error.
  3. It’s important an Autotune is carried to optimise motor control prior to running the lift on Test.
  4. The parameter changed should be saved, however they will need to be set back to TVC default values once the encoder is fitted.
