Line supply

Cabinet units can be directly connected to three-phase line supplies (refer to Technical Data for the nominal data).

The feeder cables to the drive converter must be protected against short-circuit and overload (DIN VDE 0160/DIN VDE 0100, Part 540). The cable is entered at the bottom side.

Main switch

For cabinet units from 15 to 1200 A, the three-phase line supply is connected to the unit via the main switch =D3-Q11. Cabinet units larger than 1200 A have an electrically-actuated circuit breaker =D3-Q11 and a main switch =D3-S11.

Main contactor/circuit breaker

The main contactor =D3-K11 or the circuit breaker =D3-Q11 can be switched-in or -out using a relay, mounted in the cabinet unit via the field contactor =G1-K11. A microprocessor in the drive converter automatically controls the relay at the correct instant within the power-up or power-down routine.

Circuit-breaker and motor protection circuit breaker

The main contactor = D3-K11 or the circuit breaker =D3-Q11 can be switched-in or –out using a relay, mounted in the cabinet unit via the field contactor =G1-K11. A microprocessor in the drive converter automatically controls the relay at the correct instant within the power-up or power-down routine.

Miniature circuit breaker and motor protection circuit breaker

Miniature circuit breaker and motor protection circuit-braker protect the electronics power supply, as well as the auxiliary circuits and the motor fan and the fan against short-circuit and overload.

Fuses

SITOR- or SILIZED fuse links and MCBs protect the thyristors and the field rectifier of the cabinet unit as well as the auxiliary circuits and the motor fan.

Commutating reactors

Commutating reactors for the armature- and field circuit limit the commutating dips in the line supply voltage in accordance with DIN VDE 0160. They are rated for operation with 100 % rated DC current.

Control voltage transformers

A control voltage transformer 400/230 V is used for the electronics power supply and the open-loop control. For drive converter input voltages greater than 3-ph. 400 V AC, an additional auxiliary voltage supply 3-ph. 400 V AC is required on the part of the customer. Control voltage transformers can also be supplied if requested.

Display- and operator control elements

Display- and operator

control elements

The following equipment is mounted in the cabinet doors:

• Mushroom-head pushbutton switch E-Stop, black, latching. No EMERGENCY-OFF acc. to EN 60 204-1.
• 10-turn setpoint potentiometer
• Mode selector switch, INTERNAL-EXTERNAL
• OP1S operator control panel.

The operator control panel is used to

• Set the cabinet unit parameters
• Display measured values
• The open-loop control is executed in the INTERNAL mode:
  • setpoint input via motorized potentiometer
  • power-on (I)
  • power-down (O)
  • jogging
  • reversing
• Display and acknowledge error messages

“External” operating mode

In this mode, the setpoint is entered and the equipment controlled via the terminals of the unit or via serial interfaces or optional bus connection to automation systems.

Drive converters

The following drive converters are used:

• for single-/two-quadrant operation, the SIMOREG DC MASTER 6RA70..-..S22-0.
• for four-quadrant operation, the SIMOREG DC MASTER 6RA70..-..V62-0.

The equipment options K00 (terminal expansion) and D64 (Operating Instructions, multilingual, as well as the operator control program DriveMonitor on CD-ROM), are included in the scope of supply.

SIMOREG DC MASTER

6RA70 are fully-digital, line-commutated drive converters which are connected to three-phase line supplies. They are used to control the armature- and field circuits of variable-speed DC motors. The rated DC current, specified on the equipment rating plate (= maximum permissible continuous DC current) can be exceeded up to 1.8 times in operation. The maximum overload time depends on the overload current characteristics and the preload condition of the drive converter and is drive-converter specific. The overload capacity is configured using Catalog DA 21.1.

As a result of an integrated parameterizing device, the drive units are autonomous and no additional programming- or measuring equipment is required to parameterize them.

All of the functions of the open-loop and closed-loop control for the armature- and field circuits are realized in two high-performance 16-bit microprocessors.

The closed-loop control functions are implemented as program modules in the software, which can be linked using parameters. The drive converters have an additional series of technological functions with the software option (code S00). These include, for example, higher-level technology controllers, freely-assignable adders, multipliers and dividers, logical blocks, timers, limit value monitors, etc.The T400 technology module can be used for additional technological functions, for example, winders or synchronous controls (codes D30 to D32). The cabinet units have three serial interfaces. One is used to couple the unit to the operator panel OP1S. Two additional interfaces can be freely used, e.g. to establish a unit-unit link via the peer-to-peer protocol, couple to a PC or to an automation system via the USS protocol.

The cabinet units can be connected to PROFIBUS via the CBP2 interface module (code D36).
