SIMOREG DC-MASTER Operating Instructions
Derating as a function of installation altitude:
Units can operate at altitudes of up to 4500m when the electronics and field are supplied with
voltages of 460 VAC line-to-line (maximum 300 VAC to earth). The maximum permissible
voltage up to 5000m is 400 VAC line-to-line (maximum 230 VAC to earth).
Units with a rated supply voltage of 950V armature can be operated up to maximum 4000m
above sea level without derating.
933 VAC is the maximum permitted armature supply voltage up to 4500m.
881 VAC is the maximum permitted armature supply voltage up to 5000m.
At higher altitudes, or at higher voltages, only basic insulation is afforded rather than "Protection
by electrical separation".
The control stability (closed-loop PI control) is referred to the rated motor speed and applies
when the SIMOREG converter is warm. The following conditions are applicable:
- Temperature changes of ±10 K
- Line voltage changes corresponding to +10% /
5% of the rated input voltage
- Temperature coefficient of temperature-compensated tacho-generators 0.15‰ per 10 K
(applies only to analog tacho-generator)
- Constant setpoint (14-bit resolution)
6) Also refer to Section 3.3 and 9.
7) Also permissible for 2AC 460 (+15% / – 20%).
8) Motor protection type 3RV1011-0DA1 or 3RV1011-0EA1 trimmed to 0.3A manufactured by
Siemens is to be provided for blower motor type R2D220-AB02-19 in drive models 6RA7081,
6RA7085, 6RA7087 with rated input voltage 400V or 575V.
9) Motor protection type 3RV1011-0KA1 or 3RV1011-1AA1 trimmed to 1.25A manufactured by
Siemens is to be provided for blower motor type RH28M-2DK.3F.1R in drive models 6RA7090,
6RA7091, 6RA7093, 6RA7095 with rated input voltage 400V or 575V.
10) Operation in the extended frequency range between 23 Hz and 110 Hz is available on request.

Degree of pollution 2:
Under normal conditions, only non-conductive pollution occurs. Occasionally, pollution may
become conductive for a short period of time when the electronic equipment is not in operation.
