31 Motor therm prot
Motor temperature measurement and thermal protection
settings.
31.01
Mot temp1 prot
Selects how the drive reacts when motor overtemperature is
detected by motor thermal protection 1.
No
Motor thermal protection 1 inactive.
0
Alarm
The drive generates alarm MOTOR TEMPERATURE when
the temperature exceeds the alarm level defined by
parameter
1
Fault
The drive generates alarm MOTOR TEMPERATURE or trips
on fault MOTOR OVERTEMP when the temperature exceeds
the alarm/fault level defined by parameter
/
(whichever is lower).
2
31.02
Mot temp1 src
Selects the means of temperature measurement for motor
thermal protection 1. When overtemperature is detected the
drive reacts as defined by parameter
Note:
If one FEN-xx module is used, parameter setting must
be either KTY 1st FEN or PTC 1st FEN. The FEN-xx module
can be in either Slot 1 or Slot 2.
Estimated
The temperature is supervised based on the motor thermal
protection model, which uses the motor thermal time constant
(parameter
) and the motor load curve
(parameters
). User tuning is typically needed
only if the ambient temperature differs from the normal
operating temperature specified for the motor.
The motor temperature increases if it operates in the region
above the motor load curve. The motor temperature
decreases if it operates in the region below the motor load
curve (if the motor is overheated).
WARNING!
The model does not protect the motor if
it does not cool properly due to dust and dirt.
0
KTY 1st FEN
The temperature is supervised using a KTY84 sensor
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 1 is used for the
temperature supervision.
Note:
This selection does not apply to FEN-01.
2
KTY 2nd FEN
The temperature is supervised using a KTY84 sensor
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 2 is used for the
temperature supervision.
Note:
This selection does not apply to FEN-01.
3
PTC JCU
The temperature is supervised using a PTC sensor
connected to DI6.
4
PTC 1st FEN
The temperature is supervised using 1...3 PTC sensors
connected to encoder interface module FEN-xx installed in
drive Slot 1/2. If two encoder interface modules are used,
encoder module connected to Slot 1 is used for the
temperature supervision.
5
