2.2 List of parameters
If value = 0:
An alarm is output and I_max is not reduced.
If value = 1:
An alarm is output and a timer is started. A fault is output if the alarm is still active after this timer has expired.
- for KTY84, the following applies: I_max. is reduced
- for PTC, the following is valid: I_max. is not reduced
If value = 2:
An alarm is output and a timer is started. A fault is output if the alarm is still active after this timer has expired.
If value = 12:
Behavior is always the same as for value 2.
For motor temperature monitoring without temperature sensor, when switching off, the model temperature is saved in
a non-volatile fashion. When switching on, the same value (reduced by p0614) is taken into account in the model
calculation. As a consequence, the UL508C specification is fulfilled.
Description: Sets the winding time constant.
The time constant specifies the warm-up time of the cold stator winding when loaded with the motor standstill current
(rated motor current, if the motor standstill current is not parameterized) up until a temperature rise of 63 % of the
continuously permissible winding temperature has been reached.
Dependency: This parameter is only used for synchronous motors (p0300 = 2xx, 4).
Refer to: r0034, p0612, p0615
Notice: This parameter is automatically pre-set from the motor database for motors from the motor list (p0301).
When selecting a catalog motor, this parameter cannot be changed (write protection). Information in p0300 should be
carefully observed when removing write protection.
When exiting commissioning, p0612 is checked, and where relevant, is preassigned to a value that matches the
motor power, if a temperature sensor was not parameterized (see p0601).
Note: When parameter p0611 is reset to 0, then this switches out the thermal I2t motor model.
If no temperature sensor is parameterized, then the ambient temperature for the thermal motor model is referred to
p0625.
Description: Setting to activate the motor temperature model.
Dependency: For synchronous motors, when exiting commissioning, temperature model 1 is automatically activated if a time
constant has been entered in p0611.
Refer to: r0034, p0604, p0605, p0611, p0615, p0625
Note: Mot_temp_mod: motor temperature model
Re bit 00:
This bit is used to activate/deactivate the motor temperature model for permanent-magnet synchronous motors.
Re bit 01:
This bit is used to activate/deactivate the motor temperature model for induction motors.
