Description
The temperature is supervised using a Pt100 sensor
connected to the first available analog input and analog
output on I/O extensions installed on the drive.
The temperature is supervised using two Pt100 sensors
connected to the first available analog input and analog
output on I/O extensions installed on the drive.
The temperature is supervised using three Pt100 sensors
connected to the first available analog input and analog
output on I/O extensions installed on the drive.
Defines the alarm limit for motor thermal protection 1 (when
parameter 31.01 Mot temp1 prot
Fault).
Motor overtemperature alarm limit.
Defines the fault limit for the motor thermal protection 1 (when
parameter 31.01 Mot temp1 prot
Motor overtemperature fault limit.
Selects how the drive reacts when motor overtemperature is
detected by motor temperature protection 2.
Motor temperature protection 2 inactive.
The drive generates alarm MOTTEMPAL2 when the
temperature exceeds the alarm level defined by parameter
31.07 Mot temp2 almLim.
The drive generates alarm MOTTEMPAL2 or trips on fault
MOTTEMP2 when the temperature exceeds the alarm/fault
level defined by parameter
Mot temp2 fltLim (whichever is lower).
Selects the means of temperature measurement for motor
thermal protection 2. 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.
The temperature is supervised based on the motor thermal
protection model, which uses the motor thermal time constant
(parameter 31.14 Mot therm
(parameters 31.10...31.12). 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.
The temperature is supervised using a KTY84 sensor
connected to drive thermistor input TH.
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.
