If replacing a motor encoder on a permanent magnet machine (i.e Endat encoder) then ropes will have to be lifted and a rotational auto-tune will be required. When replacing an incremental encoder on an induction motor a static auto-tune would in most cases be sufficient.

Please refer to job contract manual for relevant auto-tune procedure.

1. Changes to drive parameters must be manually saved otherwise they will be lost after power-down.
2. Navigate to the beginning of any menu which will have a number followed by 00 i.e 1.00 or 2.00.
3. Press ‘M’ until the cursor flashes on the value (which will be 0).
4. Using the keypad change this 0 to 1000 and press M followed by the red reset button. The 1000 will then change back to 0. This indicates that the parameters have been saved. If the value of 1000 does not change back to 0 then the save has not been successful, repeat the process. To confirm parameters have saved, power down the drive i.e turn off mains isolator, UPS if fitted and disconnect any backup batteries. Then reinstate the supply and check the last parameter edited.

Note: DO NOT change parameter 0.48 or 11.31 as this will default the drive parameter file.

• Set parameter 3.24 to 1
• Set parameter 3.40 to 0

In order to return the drive mode back to ‘closed loop’ set the following parameters.

• Set parameter 3.24 to 0
• Set parameter 3.40 to 1

These are hardware faults, drive must be removed. Please contact TVC to discuss options for replacement.

Please refer to relevant contract manual for full description of these trips but here are some common causes.

Check the following:

• Brake is lifting correctly. (Check Brake and Brake Circuit).
• Lubricate car/counterweight guides.
• Check for stiction in car/counterweight guides.
• Check motor encoder wiring.
• Possible faulty motor encoder.
• Excessive Accel/Decel rates.
• Check motor encoder coupling.

1. Check Brake Apply Delay #D05 Is Not Set To Zero (Default 500ms)

1. Check Drive Current #J22 Is Not Above motor rated current #B02
2. Check #B16 Is Set to Maximum

1. The Error is Between Profile Speed #J39 & Actual Speed #J40.  Check Gains i01 i02 Starting Gains, i06 & i07 Running Gains, Distance Error Can be monitored in #J56
2. Check encoder is in Feedback Mode #C14
3. This could also be a balance issue

1. Check #F27 is set back to D03

1.  If replacing a Motor Encoder on a Permanent Magnet Machine (i.e Endat Encoder) we would recommend a rotational autotune is carried out. However, a Static tune can also be carried out, but it is advisable to do it 3 consecutive times. Making sure the learnt Phase Angle C.13 on each attempt come backs with a value less a couple degrees deviation.
2. When replacing an Incremental Encoder on an Induction Motor a Static Auto-Tune would in most cases be enough. Please refer to job contract manual for relevant auto-tune procedure.

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

1. Changes to drive parameters must be manually saved otherwise they will be lost after power down
2. Navigate to the beginning of any menu which will have a letter followed by 00 i.e A.00 or E.00
3. Press ENTER (button above Red button) until the cursor flashes on 00
4. Using the keypad Navigate UP and select SAVE PARAMETERS then press ENTER, followed by the Red Reset Button. The text SAVE PARAMETER will then change back to 0. This indicates that the parameters have been saved. To confirm parameters have saved, power down the drive i.e turn off mains isolator, UPS if fitted and disconnect any backup batteries. Then reinstate the supply and check the last parameter edited.
