A4H124-24TX P0973JM switches

All data only apply for SIEMENS pre–assembled cables as these are correctly dimensioned regarding the cable cross–sections. For SIMODRIVE connection systems and also for the measuring system suppliers, remote/sense operation is only possible for encoder systems with voltage signals. For motor measuring systems and mounted SIMODRIVE sensor encoders, the sense lines are connected in the encoder or in the connector on the encoder side. For third–party encoder systems, the customers must make the appropriate connections.For SIMODRIVE, an internal 5 V is provided to supply encoders. When using SSI encoders, the power supply voltage must be externally connected to the encoder cable.

Encoder signal input (for encoders with current signals) at the signal amplification electronics (SVE). A 9–pin flange–mounted socket with socket contacts for standard round encoder connectors is provided at the SVE. The input is located on the side with the PE connection.Output of the SVE (connection to the SIMODRIVE controls, input at the direct measuring system for voltage signals). A 12–pin flange–mounted socket with plug contacts for standard round encoder connectors is provided at the SVE.

Encoder power supply for SSI encoders

The encoders must be supplied with a separately regulated 24 V voltage (e.g. SITOP power) in order to avoid disturbances/noise due to contactors, etc. The external 24 V power supply must have ”safe separation” (PELV). Filter data: – The special filter is required in order to filter–out noise and disturbances – Maximum continuous operating current = 0.8 A (use a fuse!) – Max. voltage = 30 V – One filter is designed for two encoders with a maximum current = 0.4 A The 24 V supply (reference potential) should be connected to the electronics ground of the system (e.g. terminal X131 on the NE module) if this connection is not already provided in the encoder. Maximum cable length between the 24 V supply and the filter  10 m Maximum encoder cable = 40 m The technical data of the encoder manufacturer must be carefully observed. Third–party encoders must be connected using the adapter cables provided by the particular manufacturer.

Signal amplifier electronics

 The signal amplifier electronics (SVE) is used for encoders with current signals between the encoder and drive module to convert the current signals into voltage signals 1 Vpp . The signal amplifier electronics were developed for optical encoder systems equipped with photodiodes and no additional supplementary electronics (example, ROD 456 from the Heidenhain company). However, there are many encoder systems in the market with integrated electronics where the behavior of current signals is only roughly emulated. As a result of the many options available, a general statement regarding the compatibility between the encoder, SVE and closed–loop control cannot be made. Notice For new applications, no longer use encoders with current signals, as voltage signals offer a higher noise immunity. The signal amplification electronics can be used in conjunction with the following control modules: SIMODRIVE 611 digital High Standard or High Performance SIMODRIVE 611 universal HRS/E HRS for encoders with sin/cos 1Vpp HLA module ANA module
