6.34.2 Change the unit (A/V) from a percentage of current and
voltage
f701 : Current/voltage unit selection
 Refer to section 5.10.1.
6.34.3 Display the motor or the line speed
f702 : Frequency free unit display magnification
f703 : Frequency free unit coverage selection
f705 : Inclination characteristic of free unit display
f706 : Free unit display bias
 Refer to section 5.10.2.
6.34.4 Change the steps in which the value increment
f707 : Free step 1 (1-step rotation of setting dial)
f708 : Free step 2 (panel display)
 Function
Changeable step width can be changed at panel frequency setting.
This function is useful when only running with frequencies of intervals of 1 Hz, 5 Hz, and 10 Hz units.
Note 1: The settings of these parameters don't work when the free unit selection () is enabled.
Note 2: In case setting other than 0 to f707 and increasing frequency by turning the setting dial to the
right, frequency will not be increased beyond this point with the hi alarm when the frequency
exceeds ul (Upper limit frequency) with just one more step rotation.
Similarly, when decreasing the frequency by turning the setting dial to the left and if the frequency
falls below ll (lower limit frequency) with just one more step rotation, the lo alarm is displayed in
advance and the frequency cannot be lowered beyond this point.
 When f707 is not 0.00, and f708 = 0 (disabled)
Under normal conditions, the frequency command value from the operation panel increases by 0.1 Hz when
you turn the setting dial to the right. If f707 is not 0.00, the frequency command value will increase by the
value with f707 each time you turn the setting dial to the right by 1 step. Similarly, the frequency command
value from the operation panel will decrease by the value set with f707 when you turn the setting dial to
the left by 1 step.
