Base Frequency Voltage
This parameter Enables/Disables the Voltage Compensation function.
This function provides an output waveform adjustment that compensates
for changes in the input voltage.
Settings:
0 — Disabled
1 — Supply Voltage Compensation
2 — Output Voltage Limitation
3 — Supply Voltage Compensation with Output Voltage
Direct Access Number —

Dynamic Braking Resistance (Not Used)
Program
Protection
Dynamic Braking
This parameter is model-specific and has no function on the W7B ASD.
This parameter is used to input the resistive value of the Dynamic
Braking Resistor.
For additional information on selecting the proper resistance value for a
given application contact the Toshiba Customer Support Center.
Note:
Using a resistor value that is too low may result in system
damage.
Direct Access Number —

Dynamic Braking
This parameter is model-specific and has no function on the W7B ASD.
This parameter is used to input the wattage of the Dynamic Braking
Resistor.
For additional information on selecting the proper resistor wattage value
for a given application contact the Toshiba Customer Support Center.
Note:
Using a resistor with a wattage rating that is too low may result
in system damage.

Units — kW
Ridethrough Time
Program
Protection
Undervoltage/Ridethrough
In the event of a momentary power outage, this parameter determines
the length of the Ridethrough time. During a Ridethrough, regenerative
energy is used to maintain the control circuitry settings; it is not used to
drive the motor.
The Ridethrough will be maintained for the number of seconds set using
this parameter.
Note:
The actual Ridethrough Time is load-dependent.
Direct Access Number —
F310
Parameter Type —
Numerical
Factory Default —
2.00
Changeable During Run —
Yes
Minimum — 0.00
Maximum — 320.00
Units — Seconds
