Functions
 This parameter is enabled only when Frequency Reference Selection A001 is set to "01: Control
circuit terminal block" or "02: Digital Operator" or during multi-step speed operation. Note that "01:
Control circuit terminal block" can be used only when the analog command held (AHD) is enabled.
For details, refer to "Analog Command Held Function (AHD)" on page 5-39.
 This function is disabled when an external analog input is used for frequency reference, or it
cannot be used to set a Jogging Operation frequency.
Reference
The stored frequency set value can also be cleared. The frequency reference that has been
adjusted by UP/DWN can be cleared by allocating "29: UDC" to a multi-function input terminal and
then turning ON/OFF the UDC terminal. After clearing the data, the set value conforms to the
setting of C104.
Output Voltage Gain
The voltage output by the Inverter can be changed based on the voltage selected by Motor
Incoming Voltage Selection (A082/A282) which is handled as 100%.
Motor hunting can be avoided by lowering the gain.
If the control method is Sensorless Vector Control (A044/A244 = 03), the setting change is
effective only while operation is stopped. After the setting has been changed, be sure to turn
Reset (RS terminal) to ON and then OFF. The motor parameter is recalculated after the reset.
Do not change the setting significantly during operation. (As a guide, keep the change to within
10%). A sudden change in output voltage may trigger an overcurrent trip.
