Parameters
1-82 Min Speed for Function at Stop [Hz]
Range: Function:
0 Hz [0 - 20 Hz] Set the output frequency at which to
*
activate 1-80 Function at Stop.
1-90 Motor Thermal Protection
Option: Function:
Using , the motor temperature is calculated
based on frequency, speed and time. Trane
recommends using the function, if a
thermistor is not present. The functionality is
the same for asynchronous motors and PM
motors.
[0] No protection Disables temperature monitoring.
[1] Thermistor A thermistor gives a warning if upper limit of
warning motor temperature range is exceeded,
[2] Thermistor A thermistor gives an alarm and makes the
trip frequency converter trip if upper limit of
motor temperature range is exceeded.
[3] ETR warning If calculated upper limit of motor
1 temperature range is exceeded, a warning
occurs.
[4] ETR trip 1 If 90% of calculated upper limit of motor
temperature range is exceeded, an alarm
occurs and frequency converter trips.
1-93 Thermistor Source
Option: Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
Select the input which the thermistor (PTC
sensor) should be connected. When using an
analog input, the same analog cannot be
used as a reference in 3-15 Reference Resource
1 to 3-17 Reference Resource 3.
