r0631[0...n] Motor temperature model, stator core temperature / MotTMod T_iron
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [°C]
Description: Displays the stator core temperature of the motor temperature model.
r0632[0...n] Motor temperature model, stator winding temperature / MotTMod T_copper
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [°C]
Description: Displays the stator winding temperature of the motor temperature model.
r0633[0...n] Motor temperature model, rotor temperature / MotTMod T_rotor
VECTOR Can be changed: -
Data type: Floating Point
P-Group: Motor
Min
- [°C]
Description: Displays the rotor temperature of the motor temperature model.
p0640[0...n] Current limit / Current limit
VECTOR Can be changed: C2, U, T
Data type: Floating Point
P-Group: Motor
Min
0.00 [Aeff]
Description: Sets the current limit.
Dependency: Refer to: r0209, p0323
Note: p0640 is limited to r0209 and p0323. The limit to p0323 is not realized if a value of zero is entered there.
The resulting current limit is displayed in r0067. r0067 may be reduced by the thermal model of the motor module.
The torque and power limits (p1520, p1521, p1530, p1531) matching the current limit are automatically calculated
when exiting the quick commissioning using p3900 > 0 or using the automatic parameterization with p0340 = 3, 5.
p0640 is pre-assigned as follows using the automatic parameterization (p0340 = 1, p3900 > 0):
- for induction motors: p0640 = 1.5 * p0305
- for synchronous motors (only for servo drives, refer to p0107): p0640 = p0338
The parameter is therefore also limited to the maximum converter current (r0209) and the maximum motor current
(p0323). Limiting to p0323 is only realized if p0323 > 0.
The following applies for vector drives (refer to p0107): p0640 is limited to 4.0 * p0305.
