1) The armature/field supply voltage can be less thanthe 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 K 1 (DC current) as a function of the coolant temperature (see P077 Operating Instructions).
K1 > 1 only permissible where K1 * K2 ≤ 1st overall reduction factor K = K1 * K2 (K2 see footnote 4).

b) Not permissible when T400 or OP1S are used.

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 R2D220-0AB02-19 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.

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