Auto Voltage Regulation Default Setting: 00
Settings:
00 AVR enabled
01 AVR disabled
02 AVR disabled during decel
03 AVR disabled during stop
• AVR function automatically regulates the AC drive output voltage to the Maximum
Output Voltage (P0.00). For instance, if P0.00 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 Stall Prevention Default Setting: 00
Range: 00 Enable Over-voltage Stall Prevention
01 Disable Over-voltage Stall 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.
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. If deceleration time is critical for the application, a dynamic braking
resistor should be used. Set this parameter to 01 (disable) when using a dynamic
braking resistor.
