Ordering guidelines

Standard cabinet

Observe the following points when ordering a cabinet without options:

• Every standard cabinet has a setpoint potentiometer fitted in the door as well as a switch with which the setpoint input can be selected between this potentiometer and another input.
• An outgoing circuit with a motor circuit breaker is provided for each of the fan motors of the DC motor, as listed on pages 31 and 32. In the case of fan motors with a voltage other than 400 V, it is essential to specify the fan voltage (option Y01), otherwise 400 V will be assumed as standard.
• When using cabinet units with a mains voltage greater than 415 V, a control voltage of 3-ph. 400 V must be provided for excitation, motor fan and internal cabinet control. The current rating required for this supply is listed on pages 18 and 19 for the various types. When using cabinets for voltages up to and including 415 V, this voltage is derived from the mains supply. In addition to the switching devices for setpoint input, the door also includes an E-STOP button and the OP1S control panel for parameterization and local control of the converter. Furthermore, the door includes a switch for the control voltage in the case of units of 1500 A and above, or those with mains voltages greater than 415 V.
• The “E-STOP” button fitted as standard is not an EMERGENCY OFF function. Only the supply (armature and field) is disconnected from the mains, and the drive coasts. The control voltage circuit is still live.
• The converter unit has 4 digital inputs with relay couplers which are designed as standard by the customer with a 230 V coil (specify option C51 for 24 V coil).
• Please note with standard cabinets that it is assumed that the mains voltage is the same as the rated unit voltage, i.e. 400 V, 460 V, 500 V, 690 V, 830 V. Please specify other mains voltages and frequencies using option V48.

Ordering

Always pass on as much information as possible when ordering cabinet units 6RM70. When ordering cabinets for mains voltages greater than 400 V, and if a 3-ph. 400 V control voltage is not available, it is advantageous to know all data of the outgoing circuits to be supplied (field, motor fan). The matching transformers can then be designed according to the drive. The following data are generally important:

• Contact partner for any queries.
• Motor data (armature, field, cooling, pick-up) or, if a Siemens motor is used, its Order No. including all options.
• Power/current/voltage of the fan motor or, if none is present (external ventilation using pipe system), option W15.
• Specify different degrees of protection or regulations together with the order.
• If available, specify duty cycle.

Notes

• An additional cabinet may be necessary when combining certain options, e.g. A45 “Overvoltage protection”, W10 “Radio interference suppression filter”, mains voltage greater than 400 V without the availability of a 400 V control voltage supply with relatively large control voltage transformers.
• The set values for the motor circuit breakers must be checked during commissioning.
• The scope of delivery includes the hardware, but not parameterization and commissioning.
• With a mains voltage less than or equal to 415 V/50 Hz, the motor fan and the internal cabinet supplies are derived from the primary current path and also supplied with this voltage. With mains voltages greater than 415 V/50 Hz, an external supply provided by the customer is expected for the motor fan and auxiliaries. This must be 3-ph. 400 V. When specifying the option V60 (60-Hz frequency), the control voltage provided by the customer must be 3-ph. 460 V/60 Hz.
