Supply Voltage Correction
Program  Protection  Base Frequency Voltage
This parameter Enables/Disables the Voltage Compensation function.
When Enabled, this function provides a constant V/f ratio during periods of
input voltage fluctuations.
Settings:
Disabled (Output Voltage Unlimited)
Enabled (Supply Voltage Compensation)
Disabled (Output Voltage Limited)
Enabled (Supply Voltage Compensation w/Output Voltage Limited)
Dynamic Braking Resistance
Program  Protection  Dynamic Braking
This parameter is used to input the resistive value of the Dynamic Braking
Resistor being used.
Light-duty and heavy-duty resistors vary from a few ohms to several hundred
ohms. The appropriate resistance size will be typeform- and application-
specific.
See the section titled Dynamic Braking Resistor Specifications on pg. 274
additional information on using the DBR system and for assistance in selecting
the appropriate resistor for a given application.
Note: Using a resistor value that is too low may result in system
damage.
Continuous Dynamic Braking Capacity
Program  Protection  Dynamic Braking
This parameter is used to input the wattage of the Dynamic Braking Resistor.
See the section titled Dynamic Braking Resistor Specifications on pg. 274
additional information on using the DBR system.
Note: Using a resistor with a wattage rating that is too low may result
in system damage.
Ridethrough Time
Program  Protection  Retry/Restart
In the event of a momentary power outage, this parameter determines the length
of the Ridethrough time.
The Ridethrough will be maintained for the number of seconds set using this
parameter.
See parameter F302 for additional information on the Ridethrough function.
Note: The actual Ridethrough Time is load-dependent.
