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:
0 — Disabled (Output Voltage Unlimited)
1 — Enabled (Supply Voltage Compensation)
2 — Disabled (Output Voltage Limited)
3 — 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.
Dynamic Braking Protection on pg. 280
for 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.
Direct Access Number — F308

for 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
for additional information on the Ridethrough function.
Note:
The actual
Ridethrough Time
is load-dependent.
Direct Access Number — F310
Parameter Type —

Changeable During Run —
Yes
Minimum — 0.1
Maximum — 320.0
