 Note!

At present, relative current values are still expected for the specification of the

interpolation 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.

Parameter Setting Info

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 - laminated core/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 for 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 range for 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 %
