r0334[0...n] Actual motor-torque constant / Mot kT act
Access level: 4
Can be changed: -
Units group: 28_1
Min
- [Nm/A]
Description: Displays the torque constant of the synchronous motor used.
Dependency: IEC drives (p0100 = 0): unit Nm / A
NEMA drives (p0100 = 1): unit lbf ft / A
Note: This parameter is not used for induction motors (p0300 = 1xx).
For synchronous motors, parameter r0334 is calculated from p0305, p0307 and p0311.
p0335[0...n] Motor cooling type / Motor cooling type
Access level: 2
Can be changed: C(1, 3), T
Units group: -
Min
0
Description: Sets the motor cooling system used.
Value: 0:

128:
Dependency: For 1LA7 motors (refer to p0300), the parameter is pre-set as a function of p0307 and p0311.
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The parameter influences the thermal 3-mass motor model.
1LA7 motors, frame size 56 are operated without fan.
r0337[0...n] Rated motor EMF / Mot EMF_rated
Access level: 4
Can be changed: -
Units group: -
Min
- [Vrms]
Description: Displays the rated EMF of the motor.
Note: EMF: Electromagnetic force
