Note!
Currently relative current values are still expected for the specification of the
grid points in subcodes 2, 4, 6, 8 of C01196 . This example, however, already uses
relative torque values the entry of which shall be possible at a later date.
Parameters Setting Information
C00128/1 1.0 min Thermal time constant - winding
• Is unknown and is therefore deactivated by setting C01195 = "0 %".
C00128/2 5.0 min Thermal time constant - steel plates/housing
C01195 0 % Percentage of the winding in the final temperature.
C01196/1 0 % Speed = "0" (standstill)
C01196/2 Permissible motor torque at standstill
Self-ventilated: 60 % = 6.1 Nm / 10.2 Nm * 100 %
Forced ventilated: 100 % = 10.2 Nm / 10.2 Nm * 100 %
C01196/3 Speed n
2
, from which the torque must be reduced with self-ventilated motors.
Self-ventilated: 43 % = 600 rpm / 1410 rpm * 100 %
Forced ventilated: 0 % No torque reduction required.
C01196/4 100 % Permissible motor torque at speed n
2
(torque reduction)
C01196/5 100 % Rated speed (≡ 1410 rpm)
C01196/6 100 % Permissible motor torque at rated speed (≡ 10.2 Nm)
C01196/7 213 % Speed above the rated speed (in the field weakening in case of asynchronous
motors)
= 3000 rpm / 1410 rpm * 100 %
C01196/8 44 % Permissible motor torque at speed n
4
(field weakening)
= 4.5 Nm / 10.2 Nm * 100 %
