Siemens SINAMICS G120X - CO;BO: Mot_Temp Status Word Faults;Alarms; Mot_Temp ZSW F;A

Description: Sets the boost factor for the copper losses at standstill for motor temperature models 1 and 3.
The entered factor is active for speed n = 0 [rpm].
This factor is linearly reduced down to 1 between speeds n = 0 ... 1 [rpm].
The following values are required to calculate the boost factor:
- stall current (I_0, p0318, catalog value)
- thermal stall current (I_th0, catalog value)
The boost factor is calculated as follows:
- p5350 = (I_0 / I_th0)^2
Dependency: See also: p0318, p0612, p5390, p5391

NOTICE
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note
Temperature model 1 (I2t):
The following applies for firmware version < 4.7 SP6 or p0612.8 = 0:
- parameter p5350 is not active. Internally, a fixed boost factor of 1.333 is used as basis for the calculation.
The following applies from firmware version 4.7 SP6 and p0612.8 = 1:
- parameter p5350 becomes active as described above.

Note
For bit 00, 04:
The motor temperature is measured using a temperature sensor (p0600, p0601). When the bit is set, a high
temperature is identified, and a corresponding signal is additionally output.
For bit 01, 05:
The motor temperature is monitored based on a temperature model (p0612). When the bit is set, a high temperature
is identified, and a corresponding signal is additionally output.
For bit 02:
The encoder temperature is measured using a temperature sensor. When the bit is set, a high temperature is identified,
and a corresponding signal is additionally output.
For bit 08:
When reaching the motor temperature alarm threshold, reduction of the maximum current is set as response (p0610
= 1). When the bit is set, reduction of the maximum current is active.
