Supply Voltage Compensation
Program Protection Parameters
⇒
This parameter Enables/Disables the Voltage Compensation function. This
function provides an output waveform adjustment that compensates for changes
in the input voltage.
Dynamic Braking Resistance
Program ⇒ Protection Parameters
This parameter is used to input the resistive value of the Dynamic Braking
Resistor if so equipped.
For additional information on selecting the proper resistance value for a given
application contact Toshiba's Marketing Department.
Note: Using a resistor value that is too low may result in system damage.
Dynamic Braking Resistance Capacity
Program ⇒ Protection Parameters
This parameter is used to input the wattage of the Dynamic Braking Resistor
if so equipped.
For additional information on selecting the proper resistor wattage value for a
given application contact Toshiba's Marketing Department.
Note: Using a resistor with a wattage rating that is too low may result in
system damage.
Ridethrough Time
Program ⇒ Protection Parameters
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.
Disable Forward Run/Disable Reverse Run
Program ⇒ Frequency Setting Parameters
Disable
This parameter Enables/Disables the Forward Run or Reverse Run mode.
If either direction is disabled, commands received for the disabled direction will
not be recognized. If both directions are disabled, the received direction
command will determine the direction of the motor rotation.
