P14.12 1354 - Torque increase (2PS) 0
0 Deactivated
1 activated
Automatic increase of the output voltage (Boost) with an
increased load and low speed (e.g. heavy starting duty).
h Caution: A high torque at low speed causes a high thermal
load on the motor.
Note: If temperatures are too high, the motor should be fitted
with a fan.
P14.13 1353 - Motor (2PS), temperature protection 2
The motor temperature protection is designed to protect the motor
from overheating. It is based on a temperature algorithm and uses
the motor current (P14.1) to determine the motor load (a “Heat
protection of the motor (P8.6 – P8.9)“, page 97).

2 Error (F… 16), stop function according to P6.8.
P14.14 1469 - Motor (2PS), ambient temperature 40
Setting range: -20 – +100 °C
P14.15 1470 - Motor (2PS), cooling factor at zero frequency. 40.0
Setting range: 0.0 – 150 %
The cooling factor of the motor at zero frequency defines the ratio
for cooling the motor at the rated frequency with the rated
operational current without an external fan (a figure 85,
page 94).
P14.16 1471 - Motor (2PS), thermal time constant. 45
Setting range: 1 – 200 min
The temperature time constant determines the time-span in which
the heat calculation model achieves 63% of its end value. It
depends on the design of the motor and is different from
manufacturer to manufacturer. The larger the motor design, the
greater the time constant.
