Motor #1 Max Output Voltage - Toshiba G7 Operation Manual

F305
Overvoltage Stall
Program ⇒ Protection Parameters ⇒ Stall
This parameter Enables/Disables the Overvoltage Stall function. When
enabled, this function causes the drive to extend the decel time when the DC
bus voltage increases due to transient voltage spikes, regeneration, supply
voltage out of specification, etc. in an attempt to reduce the bus voltage.
Settings:
Enabled
Disabled
Enabled (Forced Shorted Deceleration)

Motor #1 Max Output Voltage

Program ⇒ Motor Parameters ⇒ Motor Set #1
This parameter sets the maximum value of the output voltage of the drive. The
Motor #1 Maximum Output Voltage is the Motor #1 output voltage at the
Base Frequency (F014). Regardless of the programmed value, the output
voltage cannot be higher than the input voltage.
The actual output voltage will be influenced by the input voltage of the ASD
and the Supply Voltage Compensation setting (F307).
Supply Voltage Compensation
Program ⇒ Protection Parameters ⇒ 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:
Box checked (Enabled)
Box not checked (Disabled)
Dynamic Braking Resistance
Program ⇒ Protection Parameters ⇒ Dynamic Braking
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 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 ⇒ Dynamic Braking
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 Toshiba's Marketing Department.
Note: Using a resistor with a wattage rating that is too low may result
in system damage.
