1756-L63/B processor module

If switching elements are used without leading contact, then it must be absolutely ensured that after powering–down and –up the NE module again, terminal 48 (start/contactor control) is deenergized in order to activate the precharging circuit. If this is not the case, then high re–charging currents (similar to short–circuit currents) can occur when powering–up again. These re–charging currents are not limited by the pre–charging circuit. This can trip the fuse or damage/destroy the NE module. For the subsequently described configurations, it is not absolutely necessary that a leading contact is used for the switching element: Only one NE module is connected to the switching element. Caution When using I/R modules, no additional loads may be connected to the switching element. Connection of NE modules with the same power class to one switching element. In this case, the restrictions for connecting several NE modules to a switching element must be carefully observed (refer to the following page).

General information

 The line filters limit the cable–borne noise and disturbances, originating from the converter units, to permissible EMC values for industrial environments. If the system is consequentially executed in–line with the Configuration Manual and the EMC Guidelines for SIMODRIVE, SINUMERIK, SIROTEC, then the prerequisites are created so that the limit values at the installation location will be in compliance with the EU Directives for EMC. The line filters can be used both for sinusoidal current as well as squarewave current operation. The mounting/installation and connection regulations as listed in Chapter 9.1 must be carefully observed. For more detailed information regarding an EMC–correct design, refer also to the EMC Guidelines for SINUMERIK (Order No.: 6FC5297–0AD30–0AP1). Other suitable measures can also be adopted to comply with the EMC limits. An EMC examination is necessary in particular cases. Note The line supply connection conditions as specified in Section 7.1 must always be observed. If the line supply does not comply with the requirements according to EN–/IEC 61000–2–4 Class 3, then the filters could be overloaded. The use of a matching transformer does not mean that the HFD reactor or the line filter can be omitted.

Wideband line filte

Wideband line filters function in the frequency range from 2 kHz to 30 MHz. Load frequency harmonics are effectively limited using a wideband line filter. They are required when sensitive loads, such as electronic power supplies, etc., are operated on the same line supply. This can prevent impairment, damage, and premature aging of these loads. Basic line filters function in the frequency range from 150 kHz to 30 MHz. This especially suppresses disturbances for radio–based services. ! Caution The line filters are only suitable for the direct connection to TN systems. The line filters listed conduct a high leakage current over the PE conductor. A permanent PE connection for the line filter or control cabinet is required due to the high leakage current of the line filters. Only the line filters described in this Configuration Manual should be used. Other line filters can cause line harmonics that can interfere with or damage other loads powered from the line supply. It is not permissible to connect other loads after the line filter. Measures according to DIN EN 61800–5–1 must be taken, e.g. a PE conductor 10 mm2 CU or fit an additional connection terminal for a PE conductor with the same cross–section as the original PE conductor. Optional line filter rows that are coordinated with the power range are also available with the SIMODRIVE 611 digital converter system. These line filters differ with regard to the frequency range in which they reduce the conducted emissions.
