Digital LCD Operator Display Unit Selection
The drive can display different types of engineering units for speed related parameters and monitors, acceleration and
deceleration ramp, and jerk settings when using the optional JVOP-180 LCD operator. Select the speed units using
parameter o1-03 as shown below.
Certain mechanical data must be programmed to the drive prior to setting o1-03 to 4, 5, or 6. Perform the following steps
when using one of those settings:
1. Make sure motor data is 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.
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
Motor
/n
Traction Sheave
) to parameter o1-22. If a gearbox is not used, make
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.
