Toshiba VF010H05 Manual De Usuario

•  Thermal Register Minimum: Sets the value 

in the thermal register which represents a 

motor running at the nameplate current (with 

no overheating or negative sequence currents 

present).

 

•

 Motor Design Ambient Temperature: Use the 

data from the motor manufacturer’s specifications. 

When RTDs are used, this setpoint will be the 

base point for the RTD biasing of the Thermal 

Register.

•  Motor Design Run Temperature: Use the data 

from the motor manufacturer’s specifications. This 

setpoint defines the operating temperature rise of 

the motor at full load amps or 100% load.

•  Motor Stator Max Temperature: This represents 

the maximum temperature the stator insulation 

will withstand. The user may choose to use 

the temperature setting of the insulation class 

(selected in Setpoint Page 1) or enter a specific 

maximum temperature. This value should not 

exceed the stator’s insulation temperature. This 

maximum temperature represents 100% thermal 

capacity.

•  U/B Input to Thermal Register: Always enabled. 

It allows the soft starter to use the line current 

imbalance information to bias the Thermal 

Register.

•  User Calculated K or Assign: When the setpoint 

is set to ON the controller will calculate the k 

constant factor for biasing the thermal register, or 

the user may choose to assign the k value.

SP12.4  Press Enter to CLR Thermal Register: Allows 

the level three password user to clear the thermal 

register for emergency restarts.

SP12.1  Default Display Screen: This setpoint group 

allows the user to choose the default screen the 

soft starter displays while the motor is running. 

Select the metering page number (1-3), then 

select the metering screen number. The range 

varies depending on the selected page. To display 

a default screen, program the following two 

setpoints:

•  Metering Data Page#: Range is Page 1 - 3.

•  Metering Data Screen#: If Page 1 is selected 

as the default page, then Screens 1- 10 are 

available. If Page 2, Screens 1-29 are available. 

If Page 3 is selected, then Screens 1-6 are 

available. (See Metering Menu, MP.1, for screen 

number assignment.)

 

SP12.2  Alarms: Configures the RTD failure alarm and the 

thermal register alarm.

•  RTD Failure Alarm:  If enabled, and an RTD 

shorts or open, an alarm occurs.

•  Thermal Register Alarm: Sets a level in the 

thermal register to generate an alarm when the 

Thermal Register Capacity Used has exceeded 

this level.

•  Thermal Alarm Delay: The amount of time that 

the Thermal Register Used must exceed the 

setpoint before an alarm condition will occur.

SP12.3  Thermal Register Setup Information: This 

setpoint group will configure the thermal register 

and indicate to the soft starter which inputs to use 

when thermal modeling.

•  Cold Stall Time: Enter the time from the motor 

manufacturer’s specification sheet or use the time 

defined by the OL Class. This setpoint is used to 

define the thermal capacity of the motor.

•  Hot Stall Time: Enter the amount of time 

specified by the motor manufacturer or use half of 

the time defined by the OL Class.

•  Stopped Cool Down Time: The time the motor 

requires to cool down after it has stopped. Use 

only the data provided by the motor manufacturer.  

This setpoint is used to configure the cooling rate 

of the thermal register.

•  Running Cool Down Time: The amount of 

time the motor requires for cooling down while 

running. Use only the data provided by the motor 

manufacturer.

•  Relay Measured Cool Rates: When RTDs are 

used, the soft starter can be configured to use the 

measured cool rates from the RTDs instead of the 

programmed settings. This setpoint should only be 

enabled when RTDs are present.
