1) The armature/field supply voltage can be less than the rated supply voltage armature/field (set with Parameter P078; for converters with 400 V rated voltage, input voltages of up to 85 V are permissible). The output voltage is reduced accordingly. The specified output DC voltage can be guaranteed up to undervoltages 5 % below the supply voltage (rated supply voltage armature/field)

2) Values apply to output rated DC current.

3) Load factor K1 (DC current) as a function of the coolant temperature (see P077 Operating Instructions, Section 11). K1 > 1 only permissible where K1 * K2 ≤ 1st. overall reduction factor K = K1 * K2 (for K2 see Footnote 4)

b) Not permissible when T400 or OP1S are used.

4)  Load values K2 as a function of installation altitude (see P077 Operating Instructions, Section 11); overall reduction factor K = K1 * K2 (for K1 see Footnote 3).

5) 2-ph. AC 460 (+15 % / -20 %) is also permissible

6) Operation in the extended frequency range of 23 Hz to 110 Hz is possible on request.

7) For UL systems, a Siemens motor protection circuit breaker Type 3RV1011-0DA1 or 3RV1011-0EA1, adjusted to 0.3 A for the fan motor Type R2D220-AB02-19 must be installed in 6RA7081, 6RA7085 and 6RA7087 converters with a rated voltage of 400 V or 575 V.

8) For UL systems, a Siemens motor protection circuit breaker Type 3RV1011-0KA1 or 3RV1011-1AA1, adjusted to 1.25 A for the fan motor Type RH28M-2DK.3F.1R must be installed in 6RA7090, 6RA7091, 6RA7093 and 6RA7095 converters with a rated voltage of 400 V or 575 V.

SIEMENS DC MASTER SINAMICS DCM Control Module

The SINAMICS DC MASTER Control Module offers the optimum solution when retrofitting and modernizing existing DC drives. Contrary to the SINAMICS DC MASTER DC Converter, which comprises open-loop control, closed loop control and power unit, the Control Module is especially used if, as part of the modernization, the power unit of the existing plant or system should be kept. When it comes to quality, reliability and functionality, the SINAMICS DC MASTER Control Module is exactly the same as its predecessor – the SIMOREG CM; however, when it comes to functionality, it offers new features from the range of the SINAMICS DC MASTER.

SIMOREG DC Master 6RA70 Series – SIEMENS 6RA70 Conrol Module

SIMOREG 6RA70 converters are fully digital, compact units for connection to a three-phase AC supply. They in turn supply the armature and field of variable-speed DC drives. The range of rated DC currents extends from 15 A to 3000 A, but can be expanded by connecting SIMOREG converters in parallel.
