Siemens SINAMICS G120X - DC Link Voltage Overvoltage Threshold; VDC U_Upper_Thresh; DC Link Voltage Undervoltage Threshold; VDC U_Lower_Thresh; Motor Type Selection; Mot Type Sel

Note
- Under certain circumstances, the fan can continue to run for longer than was set (e.g. as a result of the excessively
high heat sink temperature).
- For values less than 1 s, a 1 s run on time for the fan is active.
- for a PM230 power unit, sizes D - F the parameter is ineffective.
r0296 DC link voltage undervoltage threshold / Vdc U_lower_thresh
Access level: 3 Calculated: - Data type: Unsigned16
Can be changed: - Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
- [V]
Max:
- [V]
Factory setting:
- [V]
Description: Threshold to detect a DC link undervoltage.
If the DC link voltage falls below this threshold, the drive unit is tripped due to a DC link undervoltage condition.

r0297 DC link voltage overvoltage threshold / Vdc U_upper_thresh
Access level: 3 Calculated: - Data type: Unsigned16
Can be changed: - Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 8750, 8760,
8850, 8864, 8950, 8964
Min:
- [V]
Max:
- [V]
Factory setting:
- [V]
Description: Threshold to detect a DC link overvoltage.
If the DC link voltage exceeds the threshold specified here, the drive unit is tripped due to DC link overvoltage.

p0300[0...n] Motor type selection / Mot type sel
Access level: 2 Calculated: - Data type: Integer16
Can be changed: C2(1, 3) Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: 6310
Min:
0
Max:

Description: Selecting the motor type.
The first digit of the parameter value always defines the general motor type and corresponds to the third-party motor
belonging to a motor list:
1 = induction motor
2 = synchronous motor
6 = synchronous reluctance motor
xx = motor without code number
xxx = motor with code number
The type information must be entered to filter motor-specific parameters and to optimize the operating characteristics
and behavior. For example, for synchronous motors, power factor (p0308) is neither used nor displayed (in the BOP/
IOP).
The following applies for values < 100:
Motor data must be manually entered.
The following applies for values >= 100:
Motor data are automatically loaded from an internal list.
Value: 0: No motor
1: Induction motor
2: Synchronous motor
