check box should be selected. If the motor does not have a thermistor or thermal sensor, then the check box should be clear.
If the check box is selected, the drive monitors the thermal device to determine if the motor is over-heated, in which case a "th" trip
will activate on the Unidrive SP/Digitax ST.
Internally, this check box is used to configure the thermistor feature inside the Unidrive SP/Digitax ST drive. The functionality is as
follows:
If check box is selected:
EZMotion sets the Unidrive SP/Digitax ST "Analog Input 3 Mode" to Thermistor without Short-Circuit Detection Mode on power
up by setting Pr 7.15 = 8.
If check box is cleared:
EZMotion checks Analog Input 3 Mode on power-up by reading Pr 7.15. If Pr 7.15 = 8, then EZMotion changes the mode to
Voltage Mode by setting Pr 7.15 = 6. If 7.15 <> 8 then EZMotion does not modify the value of Pr 7.15.
For more details on functionality of thermistor mode, see parameter 7.15 in the Unidrive SP Advanced User Guide or the Digitax ST
User Guide.
SM-EZMotion/Unidrive SP Only - Prior to addition of this check box to PowerTools Pro, SM-EZMotion used the Drive Menu Initialize
file to configure parameter 7.15 in the Unidrive SP drive. If an old file has been upgraded to work with this feature, it may be
necessary to remove the line from the Drive Menu Initialize file that configures this parameter (i.e. Menu.7.15 = 8 'Analog Input 3
should be....). For more information on this, see the Drive Menu Initialize View on page 73.
NOTE
This parameter only applies to thermal devices connected to the Unidrive SP/Digitax ST Encoder Port or Pin 8 on the Unidrive SP
Control Connectors and NOT to thermal devices connected to the encoder port on a SM-Universal Encoder Plus module. Users
must employ parameter x.12 on the encoder module if the thermal device is attached to the module.
Braking Resistor Temperature Monitor Disable - Digitax ST Drives Only
When this check box is clear the internal braking resistor temperature will be monitored. Select the check box if no internal braking
resistor is installed in the drive or to disable the br.th trip (seeFigure 59).
Motor Tab
Figure 59:
The Motor Tab on the Drive/Encoder view is used for many different functions:
1. To see/verify the motor data for a standard motor that has been selected
2. To create a new motor entry in the .ddf file
3. To Run an Auto-Tune
4. To store Auto-Tune results into an existing configuration
