Parameters
7.3 Parameters
p5350[0...n]
Mot_temp_mod 1/3 boost factor at standstill / Standst boost_fact
Access level: 2
Can be changed: T, U
Unit group: -
Min:
1.0000
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

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.
