Chapter 5 Parameters|VFD-S Series
Revision August 2006, SE08, SW V2.61 5-23
This parameter sets the Mid-Point Voltage of any V/f curve. With this setting, the V/f ratio
between Minimum Frequency and Mid-Point Frequency can be determined. This parameter
must be equal to or greater than Minimum Output Voltage (Pr.1-06) and equal to or less than
Maximum Output Voltage (Pr.1-02).
1-05 Minimum Output Frequency (Fmin) Unit: 0.1
Settings d1.0 to d60.0Hz Factory Setting: d1.0
This parameter sets the Minimum Output Frequency of the AC drive. This parameter must be
equal to or less than Mid-Point Frequency (Pr.1-03).
1-06 Minimum Output Voltage (Vmin) Unit: 0.1
Settings 115V/230V series d2.0 to d255V Factory Setting: d12.0
460V series d4.0 to d510V Factory Setting: d24.0
This parameter sets Minimum Output Voltage of the AC drive. This parameter must be equal
to or less than Mid-Point Voltage (Pr.1-04).

1-07 Output Frequency Upper Limit Unit: 1
Settings d1 to d110% Factory Setting: d100
This parameter must be equal to or greater than the Output Frequency Lower Limit (Pr.1-08).
The Maximum Output Frequency (Pr.1-00) is regarded as 100%.
Output Frequency Upper Limit value = (Pr.1-00 * Pr.1-07)/100.

Unit: 1
Settings d0 to d100% Factory Setting: d0
The Upper/Lower Limit is to prevent operation error and machine damage.
