5 Start Up
Digital Operator Display Unit Selection
The drive allows to choose between different display units for speed related parameters and monitors, acceleration and
deceleration rates and jerk settings. The units can be selected using parameter o1-03 like shown below.

When using setting 4 or 5 certain mechanical data have to be programmed to the drive prior to changing o1-03. Perform
the following steps.
1. Make sure motor data are set up correctly. Verify the setting of the maximum output frequency in parameter E1-04 and
the setting for the number of motor poles in parameter E2-04 or E5-04.
2. Set the traction sheave diameter in units of mm to parameter o1-20.
3. Set the correct roping to parameter o1-21.
4. If a mechanical gear is used, set the gear ratio (n
sure o1-22 is set to 1.0.
5. Change parameter o1-03 to setting 4 or 5. The unit and setting values of related parameters will be changed
automatically.

Auto-Tuning automatically programs the drive's motor and motor control related parameters. Select between Auto-
Tuning methods listed below.

Setting
• Rotational Auto-Tuning gives the most accurate results, and is therefore
highly recommended if possible.
T1-01 = 0
• Motor must run freely or with light load (<30%), i.e. ropes have to be
removed.
• Automatically calculates motor parameters needed for vector control.
T1-01 = 1 • Use if ropes can not be removed. Note that the accuracy is less then with
Rotational Auto-tuning.
• Used for V/f Control or in vector control modes when the drive was set up
T1-01 = 2
properly before and the motor cable has changed.
• A motor test report is available. The no-load current and the rated slip have
must be entered from the test report, all other motor-related parameters are
T1-01 = 4 calculated automatically.
• Use if ropes can not be removed and if slip and no-load current data are
available.
Setting
• Use if a motor test report is available
T2-01 = 0
• Input motor data like on test report. Make sure to convert data into the correct unit before if necessary.
• Use if a motor test report is not available
T2-01 = 1 • Input motor data like on name plate. Make sure to convert data into the correct unit before. The drive
automatically calculates the motor data.
