6 PARAMETERS
Simple variable-speed operation can be performed with the drive unit in the initial settings. Set the required parameters
according to the load and operating conditions. Use the operation panel to set or change a parameter. (Refer to Chapter 4
of the Instruction Manual (Applied) for the detailed description of parameters.
6.1 Simple mode parameters
POINT
In the initial setting, only the simple mode parameters are displayed by the Pr.160 Extended function display selection
setting. Change the Pr.160 Extended function display selection setting as required. (Refer to page 4 to change the
parameter.

Value
Range Application
1 Maximum setting 1r/min 3000r/min
0 to12000r/min/
0 to 8000r/min *
Use this parameter to set the upper limit for the rotation
speed.
2 Minimum setting 1r/min 0r/min
0 to 3600r/min/
0 to 2400r/min *
Use this parameter to set the lower limit for the rotation
speed.
