Auto Voltage Regulation Mem Addr 0604H(41541)
Default Setting: 0
Settings: 0 AVR enabled
1 AVR disabled
2 AVR disabled during decel
3 AVR disabled during Stop
• AVR function automatically regulates the AC drive output voltage to the Maximum
Output Voltage (0-00). For instance, if 0-00 is set at 200 VAC and the input voltage
is at 200V to 264VAC, then the Maximum Output Voltage will automatically be
regulated to 200 VAC.
• Without AVR function, the Maximum Output Voltage may vary between 180V to
264VAC, due to the input voltage varying between 180V to 264 VAC.
• Selecting program value 2 enables the AVR function and also disables the AVR
function during deceleration. This offers a quicker deceleration.
Over-Voltage Trip Prevention Mem Addr 0605H(41542)
Range: 0 Enable Over-voltage Trip Prevention Default Setting: 0
1 Disable Over-voltage Trip Prevention
• During deceleration, the AC drive DC bus voltage may exceed its Maximum
Allowable Value due to motor regeneration. When this function is enabled, the AC
drive will stop decelerating, and maintain a constant output frequency. The drive
will resume deceleration when the voltage drops below the factory-preset value.
Note: With moderate inertial loads, over-voltage during deceleration will not occur. For
applications with high inertia loads, the AC drive will automatically extend the
deceleration time.
