F310

 

 

 

Supply Voltage Correction

Direct Access Number —

F307

Program Protection Base Frequency Voltage

Parameter Type — Selection List

This parameter Enables/Disables the Voltage Compensation function.

Factory Default — Disabled

 

Changeable During Run — No

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

Direct Access Number —

F308

Program Protection Dynamic Braking

Parameter Type — Numerical

This parameter is used to input the resistive value of the Dynamic Braking

Factory Default — (ASD-dependent)

Changeable During Run — No

Resistor being used.

 

 

Light-duty and Heavy-Duty resistors vary from a few ohms to several hundred

Minimum — 0.5

 

 

 

ohms. The appropriate resistance size will be typeform- and application-

Maximum — 1000.0

 

specific.

 

Units — Ω

 

See the section titled Dynamic Braking Resistor Wire/Cable Specifications on

 

 

pg. 268 for more 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

Direct Access Number —

F309

Program Protection Dynamic Braking

Parameter Type — Numerical

This parameter is used to input the wattage of the Dynamic Braking Resistor.

Factory Default — (ASD-dependent)

Changeable During Run — No

See the section titled Dynamic Braking Resistor Wire/Cable Specifications on

Minimum — 0.01

 

pg. 268 for more information on using the DBR system.

 

 

 

 

 

Maximum — 600.00

 

Note:

Using a resistor with a wattage rating that is too low may result

Units — kW

 

 

in system damage.

 

 

 

 

 

 

 

Ridethrough Time

Direct Access Number —

F310

Program Protection Retry/Restart

Parameter Type — Numerical

In the event of a momentary power outage, this parameter determines the length

Factory Default — 2.0

 

Changeable During Run — Yes

of the Ridethrough time.

 

 

 

 

Minimum — 0.1

 

The Ridethrough will be maintained for the number of seconds set using this

Maximum — 320.0

 

parameter.

 

Units — Seconds

 

 

 

 

See parameter F302 for more information on the Ridethrough function.

 

 

Note:

The actual Ridethrough Time is load-dependent.
