Yaskawa recommends a full up/down travel with empty car for calibration.
Note:
You must repeat the calibration after you initialized the drive with A1-03.
To reset the calibration, set S4-01 = 0. This is recommended in case of changed operating conditions of the
elevator.
When you change the setting from S4-01 = 0 to S4-01 = 1, do a new calibration.

5 Output Phase Loss Protection
Enables or disables the output phase loss detection which is triggered when the output current falls below 5% of
the motor rated current.

0 : Disabled
1 : Triggered by a single phase loss
An output phase loss fault [LF] is triggered when one output phase is lost. The output shuts off and the motor
coasts to stop.
2 : Triggered when two phases are lost
An output phase loss fault [LF] is triggered when two output phases are lost. The output shuts off and the motor
coasts to stop.
3 : Fault at phase loss at start and during RUN
An output phase loss fault [LF] is triggered when one or more phases are lost at motor start (before the brake
opens) and when motor is moving. When LF has been detected, the motor coasts to stop.
When setting L8-07 = 3, set parameters S1-02 (only OLV and V/f) and S1-04 as follows:
• Set S1-02 [DC Injection Current at Start] to a value greater than 15%.
• Set S1-04 [DC Injection/Position Lock Time at Start] to a value greater than 100 ms.
