2.2 List of parameters
Note:
The measurement is carried out:
- For induction motors
- When vector control is active (see p1300)
- if a temperature sensor (KTY/PT1000) has not been connected
- When the motor is at a standstill when switched on
When a flying restart is performed on a rotating motor, the temperatures of the thermal motor model are set to a third
of the overtemperatures. This occurs only once, however, when the CU is booted (e.g. after a power failure).
If identification is activated, the magnetizing time is determined via p0622 and not via p0346. Quick magnetizing
(p1401.6) is de-energized internally and alarm A07416 is displayed. The speed is enabled after completion of the
measurement.
Description:
Sets the excitation time of the motor for the stator resistance identification after switching on again (restart).
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0621, r0623
Note:
For p0622 < p0346 the following applies:
If identification is activated, the magnetizing time is influenced by p0622. The speed is enabled after measurement is
complete, but not before the time in p0346 has elapsed (see r0056 bit 4). The time taken for measurement also
depends on the settling time of the measured current.
For p0622 >= p0346 the following applies:
Parameter p0622 is internally limited to the magnetizing time p0346, so that p0346 represents the maximum possible
magnetizing time during identification. The entire measurement period (magnetizing plus measurement settling time
plus measuring time) will always be greater than p0346.
Description:
Displays the stator resistance determined using the Rs identification after switching on again.
Dependency:
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0621, p0622
Description:
Defines the ambient temperature of the motor for calculating the motor temperature model.
Dependency:
Refer to: p0350, p0354
Note:
The parameters for stator and rotor resistance (p0350, p0354) refer to this temperature.
If the thermal I2t motor model is activated for permanent-magnet synchronous motors (refer to p0611), p0625 is
included in the model calculation if a temperature sensor is not being used (see p0601).
