4.2.7. 1-9* Motor Temperature
With an estimated motor temperature monitor the frequency converter is able to estimate motor temperature without having a thermistor mounted. It is thus
possible to receive a warning or an alarm, if motor temperature exceeds upper operational limit.

Motor is energized with DC braking current (par. 2-01) during start delay time.
Drive is coasted during start delay time ( Driveoff).
Function:
The Start Mode parameter is used to catch a spinning motor after eg. mains drop-out.
This function is not suitable for hoisting applications.
Catch a spinning load disabled.
Frequency converter enabled to catch spinning motor.
NB!
When catch a spinning load is enabled par. 1-71, Start Delay, and par. 1-72, Start Function, have no function.
Function:
The selected function at stop is active in following situations:
Stop command is given and output speed is ramped down to Min. Speed for Activating Functions at Stop.
Start command is removed (standby), and output speed is ramped down to Min. Speed for Activating Functions
at Stop.
DC-brake command is given, and DC-brake time has passed
While running and calculated output speed is below Min. Speed for Activating Functions at Stop.
The drive is coasted.
The motor is energized with a DC current. See par. 2-00 DC Hold Current for more information.
Function:
Set the speed at which to activate par. 1-80 Function at Stop.
Function:
Using Electronic Overload the motor temperature is calculated based on frequency, speed and time. GE recommends
using The Electronic Overload function, if a thermistor is not present.
NB!
Electronic Overload calculation is based on motor data from group 1-2*.
Disables temperature monitoring.
A thermistor connected to either digital or analog input gives a warning if upper limit of motor temperature range is
exceeded, (see par. 1-93, Thermistor Resource).
A thermistor connected to either digital or analog input gives an alarm and makes the frequency converter trip if upper
limit of motor temperature range is exceeded, (see par. 1-93, Thermistor Resource.
