5 Start Up
 Step 2: Empty Car Teach Run - P4-01 = 2
Select Nominal Speed and start a normal upward travel.
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".
• 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".
