An important application for the SIMOREG CM converter is in the retrofitting and modernization of DC drives in existing systems. In the field of DC drives, many systems exist that are older than 5 or 10 years and that still use analog technology. On retrofitting or updating these systems, the motor, mechanical components and power section are retained and only the closed-loop control section is replaced by a 6RA70 Control Module. This is an extremely economical way to obtain a modern DC drive with the complete functional scope of the well-proven, fully digital converters of the SIMOREG DC MASTER series.It is easily adapted to the configuration of the existing components by setting parameters.

 

Application

An important application for the SIMOREG CM converter is in the retrofitting and modernization of DC drives in existing systems. In the field of DC drives, many systems exist that are older than 5 or 10 years and that still use analog technology. On retrofitting or updating these systems, the motor, mechanical components and power section are retained and only the closed-loop control section is replaced by a 6RA70 Control Module. This is an extremely economical way to obtain a modern DC drive with the complete functional scope of the well-proven, fully digital converters of the SIMOREG DC MASTER series.It is easily adapted to the configuration of the existing components by setting parameters. The 6RA70 Control Module contains a power section for supplying the field with a rated current of up to 40

Design

TThe 6RA70 Control Module is characterized by its compact, space-saving design. The compact construction makes it especially easy to service since individual components are easily accessible. The electronics box contains the basic electronics as well as any supplementary boards. To support optimum utilization of the installation possibilities in the system, the 6RA70 Control Module can be separated in its depth. Furthermore, the PCBs for firing pulse generation and distribution as well as for fuse monitoring and voltage measurement are designed to be removed and mounted either partially or completely outside the unit directly on the power section and connected to the basic unit via cables. All 6RA70 Control Modules are equipped with a PMU simple operator panel in the door of the unit. The PMU consists of a five-digit, seven-segment display, three LEDs as status indicators and three parameterization keys. The PMU also features connector X300 with a USS interface in compliance with the RS232 or RS485 standard. The panel provides all the facilities required during start-up for making adjustments or settings and displaying measured values. The optional OP1S converter operator panel can be mounted either in the converter door or externally, e.g. in the cubicle door. For this purpose, it can be connected up by means of a 5 m long cable. Cables of up to 200 m in length can be used if a separate 5 V supply is available. The OP1S is connected to the SIMOREG CM unit via connector X300. The OP1S can be installed as an economic alternative to control cubicle measuring instruments which display physical measured quantities. The OP1S features an LCD with 4 x 16 characters for displaying parameter names in plain text. English, German, French, Spanish and Italian can be selected as the display languages. The OP1S can store parameter sets for easy downloading to other devices. The converter can also be parameterized via the serial interface of the basic unit by means of a generally available PC and appropriate software. This PC interface is used for start-up, for maintenance during shutdown and for diagnosis during operation and is, therefore, a service interface. Upgrades of the converter software that is stored in Flash memory can also be loaded via this interface. The field is supplied by a single-phase, semi-controlled dual pulse bridge connection B2HZ. The power section for the field is constructed with galvanically isolated thyristor modules; the heat sink is therefore at floating potential.

Mechanical stress

 

1) The field supply voltage can be less than the rated supply voltage field (set with Parameter P078.002; 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 field). 2) Adaptation to the line frequency within a frequency range of 23 Hz to 110 Hz via separate parameterization is available on request. 3) Conditions: The control stability (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 °C •    Line voltage changes corresponding to +10 % / 5 % of the rated input voltage •    Temperature coefficient of temperature-compensated tacho-generators 0.15 ‰ per 10 °C (applies only to analog tacho-generator) •    Constant setpoin (14-bit-resolution)
