• The frequency reference operates in accordance with the acceleration/deceleration time and accel-
eration/deceleration pattern (refer to 6-6-2 Acceleration/Deceleration Pattern on page 6-34) that is
adopted during operation.
•
When the UDC terminal turns ON, the frequency reference is set to 0 Hz and a deceleration stop is
performed. The UDC terminal is enabled and the frequency reference becomes 0 Hz also when the
UP terminal or DWN terminal is ON. When the UDC terminal is turned OFF during a deceleration
stop, the frequency reference is operated from 0 Hz in accordance with the UP terminal or DWN
terminal.
Note) When 0: Other than linear acceleration/deceleration, 1: S-curve acceleration/deceleration, 2: S-
curve acceleration/deceleration (Arbitrary) and 3: Curve acceleration/deceleration is selected at Accel-
eration/Deceleration Pattern Selection (3008Hex-08Hex), the output frequency changes for a while
even if the “UP” terminal and “DWN” terminal are turned OFF.

AVR
This is a function for automatically correcting the output voltage to the motor even if the inverter in-
coming voltage fluctuates.
This function is used to avoid a drop in the output torque of the motor or the overexcitation state.
Note, however, that the inverter cannot output voltage exceeding the incoming voltage to the inverter.
AVR (Automatic Voltage Regulator) Function Setting
The AVR (automatic voltage regulator) function is set to enabled or disabled by 1st AVR Function Se-
lection (301FHex-17Hex)/2nd AVR Function Selection (301FHex-18Hex).
•
The voltage output in the motor is based on the voltage selected at 1st Rated Voltage at Base Fre-
quency (3004Hex-06Hex)/2nd Rated Voltage at Base Frequency (3009Hex-04Hex).
Note, however, that the inverter cannot output voltage exceeding the incoming voltage to the inver-
ter.
