Device Data And Device Standards; Motor-Related Data; Operating The 4Q Device As A 2Q Device - Siemens SINAMICS DCM 6RA80 Faq

Device data and device standards:

pxxxxx: Setting parameters; these parameters can be modified.
rxxxxx: Display parameters or BICO output parameters; these parameters can be read only
and cannot be modified,
r50000:Display of the operating state.
r50070[xx]: Display of the MLFB (order number) of the device in the ASII code. (xx stands for
the parameter index)
r50060[6]: Software version of the SINAMICS DCM
r50063[x]: CUD information
p50067: For adapting the rated device current based on the rating class, continuous current
applies if p50067 = 1, but if p50067 > 1, the 100% current applies as actual rated DC device
current for the armature, see also p50076.
r50068: Options in accordance with the rating plate in the ASCII code.
r50069[xx]: Factory serial number of the SINAMICS DCM in the ASII code
r50071: Device rated line-side voltage armature
r50072[0]: Rated device DC current for armature acc. to the rating plate
r50072[1]: Actual rated DC device current for the armature after adaptation by means of
p50067 and p50076[0]; the smaller of the resulting values is active. Based on r50072[1], the
device can have a current load rating with a factor of up to 2.0x.
r50073[0]: Rated DC device current for the field acc. to the rating plate
r50073[1]:Actual rated DC device current for the field after adaptation with p50076[1]
r50074: Device rated line-side voltage field
p50075: Control word for overload capability for armature power unit, where p50075 = 1 or 2:
Overload capability enabled, maximum 1.8x the rated device current acc. to rating plate
(r50072[0]) possible.
p50076[0]: Adjustment of rated DC device current for armature to 1% to 100% rated current.
p50076[1]: Adjustment of rated DC device current for field to 1% to 100% of rated current
p50077: Total thermal derating factor as a function of the ambient temperature and
installation altitude of the device.
p50078[0]: Rated line voltage for converter armature
p50078[1]: Rated line voltage for converter field
p50082: Operating mode for the field
Note: Always quote MLFB (r50070), r50060[6]: Software version:
Ideally, you should send us your entire STARTER project as soon as possible.

Motor-related data:

p50100: Rated motor current, armature
p50101: Rated motor voltage, armature; for 2Q, maximum line voltage x 1.2;
for 4Q, set maximum line voltage x 1.05.
p50102: Rated motor current, field
p50171: Positive current limit for armature with reference to p50100 (set positive values)
p50172: Negative current limit for armature with reference to p50100 (set negative values)
p50180: Positive torque limit with reference to rated motor torque (set positive values)
p50181: Negative torque limit with reference to rated motor torque (set negative values)
p50104 – p50108: Settings for speed-dependent current limiting, see Section 10.19 of the
Operating Instructions. For special applications, do not use speed-dependent current limiting
for standard applications, set p50109 = 0, parameter settings p50104 – p50108 will then not
be evaluated.
Note: Notice/Danger; if positive values are set for p50172 or p50181 (or negative values are
set for p50171, p50180), the motor will accelerate uncontrolled to its maximum possible
speed limit.

Operating the 4Q device as a 2Q device:

Set p50150 = 5 and p50172 = 0
