When ordering a drive converter with options, add the suffix "-Z" to the order number and then state the order code(s) for the desired option(s) after the suffix.

Example:
6SL3710-7LE32-1AA3-Z
M07+D60+...

¹⁾ This option is listed for the input- and output-side options, but is only required once.

²⁾ The order code Y.. requires data in plain text.

Option selection matrix

Certain options can mutually exclude one another
(options that are not involved are not shown).

Electrical options

¹⁾ A combination of L87 and K82 is available on request.

Mechanical/electrical options

²⁾ If the line connection (option M13) and the motor connection (option M78) are from above, the EMC shield bus is not required in the lower cabinet area.

³⁾ Can only be selected for converters in the voltage range 400 V to 250 kW and 690 V to 315 kW. The M60 option is fitted as standard for higher outputs.

Example 1

Task:
A drive system is required for a vehicle test stand to perform exhaust gas analysis which can simulate driving profiles and cycles as encountered in everyday traffic situations. This means for the drive system that the dynamometer must be operated both in the motoring as well as regenerating modes.

A drive with regenerative feedback into the line supply is required as regenerative operation is the predominant operating mode and dynamic switching operations are required.

The max. regenerative power is 200 kW. The drive converter must have degree of protection IP54 as a result of the environmental conditions. An installation altitude of < 1000 m and 45 °C as the maximum ambient temperature can be assumed. The windings must be equipped with Pt100 resistance thermometers and monitored by the drive converter for alarm and trip. A switch disconnector must be provided to disconnect the converter from the 400 V power supply. In addition, the cabinet is to have a special paint finish in RAL 3002.

Solution:
Taking into account the derating factors for degree of protection IP54 and the increased ambient temperature of 45 °C, a converter with a minimum power rating of 223 kW must be configured.
A converter with a power rating of at least 250 kW and options M54 (degree of protection IP54), L26 (main control switch including fuses), L86 (Pt100 evaluation unit) and Y09 (special paint finish) is selected.

The ordering data are as follows:
6SL3710-7LE35-0AA3-Z
M54+L26+L86+Y09
Cabinet color RAL 3002

Example 2

Task:
A drive system is required for a conveyor belt in a brown-coal open-cast mine which is capable of both motor and generator operation. Since the conveyor belt must be capable of starting after a fault when loaded with bulk material, and it is possible for peak loads to occur where 1.5 times the power is required for up to 60 s, the drive system must be designed according to the overload requirements of such a case. The drive converter is installed in a climate-controlled container as a result of the environmental conditions typical of an open-cast mine. The installation altitude is 320 m above sea level and the maximum ambient temperature in the container is 35 °C. The drive is supplied through a converter transformer from the medium-voltage network. The drive is operated from an ungrounded line supply and must have insulation monitoring. A motor with separately-driven fan is selected here as the motor is subject to a high load torque when starting and in the lower range. The fan supply voltage is 690 V and must be drawn from the drive converter.

The required motor power is 420 kW.

Solution:
Since the converter is installed in an air-conditioned container, it can be designed with IP20 degree of protection. The 35 °C ambient temperature does not necessitate any additional derating. However, due to the specified overload conditions, the base load current IH (for high overload) must be applied. This results in a power of approx. 520 kW for the drive converter. The converter with Order No. 6SL3710-7LG35-8AA3 must be selected.

Option L87 (insulation monitoring) must be selected for insulation monitoring.

Option L19 (connection for external auxiliaries) must be selected for the controlled outgoing feeder to supply the separately-driven fan.

The ordering data are as follows:
