Step 2: Empty Car Teach Run - P4-01 = 2
The second teaching step is Empty Car Teach Run. Before doing this step make sure that Basic Calculations teaching has
been done successfully and that the distance between switches in the shaft allows at least 1 second leveling travel.
• Set parameter P4-01 to 2. The drive will show “TEACH”. If it shows “NEGTEMP” instead, double-check Oil
Temperature sensor and repeat setting P4-01 = 2.
• Select Nominal Speed and start a normal upward travel procedure in the same way as for normal elevator operation.
Even though the drive is in Programming Mode and the Alarm LED is blinking it will run with normal sequence. After
releasing the Run command, the drive will show either “SAVE” or “WRTP”.
• In both cases, press “Enter” to get back to parameter P4-01 and change it to 3. The drive will show “END” and “0”
shortly, meaning the command setting has been accepted and P4-01 is set back to “0” automatically.
In case the drive shows “SAVE” or “WRTP”, P4-01 must be set either to 3 for saving or to 0 for cancelation. When
intending to re-execute teach run in such a case, first set P4-01 to 0, then restart the procedure by setting P4-01 to 2.
“WRTP” means, the drive re-executed automatically the “Basic Calculations” Teaching. This is done when the oil
temperature differs significantly from the oil temperature while executing “Basic Calculations”.
All parameters, modified from the Teaching function can be viewed in the “Verify” and “Programming” menu. Manual
modification is possible but normally not necessary.
Precautions
• Empty Car Teach Run must be done just once. Data for Intermediate Speed and Inspection Speed are calculated
automatically.
• Don’t expect proper travel comfort during teach run. Empty Car Teach Run is just a preparation for calculating
required data. Load or oil temperature is not compensated.
• Motor contactors must be closed during the Auto-Tuning process.
• H1, H2 and HC signals must be ON when performing Auto-Tuning (keep wire link).
• The teaching can be cancelled by setting P4-01 to 0.
• In case that parameters P1-16 to P1-19 are changed, basic calculation “Teaching” is repeated automatically.
Drive Sequence and Run Command for Up-Travel
Travel Procedure
After executing Auto-Tuning and Teaching function, other adjustments are not needed in most cases.
The sequence is shown in the figure below. The Run command and Speed selection command must be set given
according to this sequence.
NO
YES
Set P4-01 = 2.
Find and remove trouble cause
* Double check sequence of the digital inputs.
* Check if mechanical or electrical installation is correct.
* Make sure that the elevator is empty.
After the travel:
Is SAVE or WRTP shown?
Select Nominal Speed and start a normal upward travel.
Set P4-01 = 3.
