1.1 Applications
Drive converter with DC current input
DC drive converters generate a variable-frequency three-phase system at the motor side from a DC supply. This
variable-frequency three-phase system is used to continuously control the speed of three-phase motors.:
SIMOVERT MASTER DRIVES can be used with a common DC link, as well as for single-motor and multi-motor
drives.
Technological functions and expansions can be realized via defined interfaces in the open-loop control section.

Description 09.97
1-2 Siemens AG 6SE7087-6BD70
SIMOVERT MASTER DRIVES Operating Instructions
1.2 Mode of operation
Converters with DC current input are suitable for coupling several converters to a common DC link bus. This
permits energy transfer between drives in the motoring and generating modes which in turn means energy
savings.
The DC converter must be connected to the DC bus through an E unit (rectifier unit) due to the pre-charging of
the DC link capacitors. If an I/R unit (rectifier and regenerative feedback unit) is used instead of the E unit, power
is fed back into the supply if the regenerative output for several drives is greater than the motor power required.
The converter is ready for operation after the DC link capacitors have been pre-charged.
The inverter, configured using IGBT modules, generates a three-phase system from the DC link voltage to feed
the motor.
SIMOVERT FC
The inverter open-loop control uses a microprocessor with an adjustable V/f characteristic. The pulse frequency
is preset to 3 kHz when the unit is shipped.
SIMOVERT FC is suitable for single-motor and multi-motor drives with:
♦Induction motors
♦Synchronous motors (SM)
♦Reluctance motors
Some of the applications are, for example:
♦Pump drives
♦Fan drives
♦Textile machines
The following can be set for the V/f characteristic:
♦Max. frequency 300 Hz
♦Operation with or without slip compensation
♦Operation with or without higher-level speed controller

09.97 Description
Siemens AG 6SE7087-6BD70 1-3
SIMOVERT MASTER DRIVES Operating Instructions
SIMOVERT VC
The inverter open-loop control uses a microprocessor and field-oriented vector control with an extremely fast
closed-loop current control. The drive can be precisely adapted to the demanded load torque as a result of the
field-oriented control, which in turn means that the drive has an extremely high dynamic performance.The pulse
frequency is preset to 2.5 kHz when the unit is shipped.
SIMOVERT VC is suitable for:
♦Induction motors in both single-motor or multi-motor drives.
For multi-motor drives, the motors within the group must be the same.
Some of the applications are, for example:
♦Winder drives
♦Rolling mill drives.
When the drive is shipped, closed-loop V/f control is preset. Closed-loop frequency control with field-oriented
vector control must be parameterized.
The converter can be set, as a result of the precise motor simulation up to a maximum frequency of 300 Hz, with
and without stall protection and with and without tachometer feedback.
SIMOVERT SC
The inverter open-loop control uses a microprocessor with field-oriented vector control, with a very fast
secondary closed-loop current control. High drive dynamic performance is achieved as a result of the field
oriented vector control. When the unit is shipped, the pulse frequency is preset to 5 kHz.
It can be set in the range from 5 kHz to 7.5 kHz.
SIMOVERT SC is suitable for:
♦Single-motor drives with permanent-field 1FT6 motors
Some of the applications are, for example
♦Winder drives,
♦Foil machines,
♦Packaging machines
After power-up, only the motor must be selected and the drive can then be enabled. The drive can be matched to
the load moment of inertia and optimized by changing a closed-loop control parameter.
The converter operates with motor identification (MOTID). The maximum stator frequency is 400 Hz.
The following operating modes can be selected:
♦Closed-loop speed control
♦Closed-loop torque control
The following encoders can be used:
♦ERN 1387 encoders
♦Encoders which are compatible to ERN 1387
♦Resolvers

WARNING
SIMOVERT MASTER DRIVES are operated at high voltages.
The equipment must be in a no-voltage condition (disconnected from the supply) before any
work is carried-out!
Only professionally trained, qualified personnel must work on or with the unit.
Death, severe bodily injury or significant material damage could occur if these warning
instructions are not observed.
Extreme caution should be taken when working-on the unit when it is open, as external
power supplies may be connected. The power terminals and control terminals can still be at
hazardous potentials even when the motor is stationary.
Hazardous voltages are still present in the unit up to 5 minutes after it has been powered-
down due to the DC link capacitors. Thus, the appropriate delay time must be observed
before opening-up the unit.
Forming the DC link capacitors:
The storage time should not exceed one year. The converter DC link capacitors must be
formed at start-up if the unit has been stored for a longer period of time.
Forming is described in the Instruction Manual, Part 2.
When the DC link is supplied from a central unit, it must be ensured that the converter is
reliably isolated from the DC link voltage!
The user is responsible, that the motor, converter and any other associated devices or units
are installed and connected-up according to all of the recognized regulations in that
particular country as well as other regionally valid regulations. Cable dimensioning, fusing,

INFORMATION AND EXPLANATIONS
The cross-sections are determined for copper cables at 40 °C (104 °F) ambient temperature (in accordance
with DIN VDE 0298 Part 4 / 02.88 Group 5).
For rated DC voltages 510 V to 780 V DC, fuses on the incoming supply side are not required as the unit has
integrated DC fuses; this assumes that the connecting cables to the DC bus are routed so that they are short-
circuit proof and the cable cannot be overloaded by other loads.

Table 3.2 Possible connection cross-sections
3.1.1 Protective conductor connection
The protective conductor should be connected-up on both the supply- and motor sides. It should be dimensioned
according to the power connections. Due to discharge currents from the noise suppression capacitors, according
to VDE 0160, a minimum cross-section of 10 mm2is required, or a second protective conductor with the same
cross-section must be routed in parallel (for cross-sections < 10 mm2).
3.2 Auxiliary power supply / main contactor or bypass contactor /
„Safety off“
3.2.1 Drive converters for rated DC voltages 280 V to 310 V DC
The auxiliary power supply and the main- or bypass contactor are connected through the 5-pin connector X9.
Connector X9 is supplied together with the connectors for the control terminal strip. Cables with cross-sections
from 0.2 mm2to 2.5 mm2(AWG: 24 to 14) can be connected at X9.
The auxiliary power supply is required if the drive converter is fed through a main-
and bypass contactor.
The main- or monitoring contactor is controlled through floating contacts -X9.4
and -X9.5 (software pre-setting).
More detailed information is provided in the Section „options“.
