Voltage Compensation
Program
Fundamental 1
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)
Direct Access Number — F307
Parameter Type — Selection List
Factory Default — Disabled (Output
Voltage Unlimited)
Changeable During Run — No
Dynamic Braking Resistance (Not Used)
Program
Protection
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.
Note:
Using a resistor value that is too low may result in system damage.
Note:
Dynamic Braking is not available on the Q9 ASD.
Direct Access Number — F308
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 0.5
Maximum — 1000.0
Units —
Ω
Dynamic Braking Capacity (Not Used)
Program
Protection
This parameter is used to input the wattage of the Dynamic Braking Resistor.
Note:
Using a resistor with a wattage rating that is too low may result in
system damage.
Note:
Dynamic Braking is not available on the Q9 ASD.
Direct Access Number — F309
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 0.01
Maximum — 600.00
Units — kW
Ridethrough Time
Program
Protection
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
for more information on the Ridethrough function.
Note:
The actual Ridethrough Time is load-dependent.
Direct Access Number — F310
Parameter Type — Numerical
Factory Default — 2.0
Changeable During Run — Yes
Minimum — 0.1
Maximum — 320.0
Units — Seconds
