MOOG D136-002-005 servo controller

There are two possibilities available for the interface between a PLC and the converter with a control board SDCS-CON-1. The first one consists of the SDCS-IOB-1 board, which can be mounted inside the converter module. The other one consists of the SDCS-IOB2x and SDCS-IOB-3 board. If these two boards are in use they must be mounted outside the converter. In addition to this an extension of I/O´s by SDCSIOE-1 is possible.

The converter with a control board SDCS-CON-2 can be connected in 4 different ways to a control unit via analogue/digital links. Only one of the four choices can be used at the same time (Description of the I/O's see chapter SDCS-CON-2). In addition to this an extension of I/O´s by SDCS-IOE-1 is possible.

The SDCS-IOB-1 board can be mounted inside the converter module equipped with a control board SDCS-CON-1. The SDCS-IOB-1 board has 8 digital inputs, 7 digital outputs, 5 analogue inputs including a tacho generator interface, 2 analogue outputs, one dedicated analogue output of actual current and incremental encoder interface.

Digital I/O board SDCS-IOB-2

As described at the beginning of the chapter, there are various options for configuring the inputs/outputs. The board IOB-2x has 8 digital inputs and 8 digital outputs. There are three different types existing, which differ at the input voltage level: SDCS-IOB-21 24...48V DC SDCS-IOB-22 115 V AC SDCS-IOB-23 230 V AC The inputs are filtered and galvanically isolated by using opto couplers. Inputs can form two galvanically separated groups by using either X7:1 or X7:2. If these boards are in use, they have to be mounted outside the DCS module. They must be mounted in a way, that the conductive supports have a good connection to ground of the installation.The cable length between X1:/X1: and X2:/X2: is 1.7 m and between X1:/X3: is 0.5 m because of EMC reasons.

supports are conductive diameter of all supports: 4.3 mm * this dimension may vary (4/5 mm) dependingon revision

Input resistance: see diagram

 Input smoothing time constant: see diagram. Smoothing time constant of channel 7 and 8 can be changed; see layout of the board. The functionality of the input channels, which will be read, can be defined by software; default values are shown within the software diagrams Power supply for digital inputs: 48V /
50mA; not galv. isolated from the DCS electronics! If the inputs are supplied from the internal +48 V (X7:3 and/or X7:4) a connection must be done from either X7:1 and/or X7:2 to ground of the DCS 500 modules. In default condition ground is identical to the converter's frame. If the inputs are supplied by any external source (+48 V DC, 115 V AC or 230 V AC) the neutral line / - line must be connected to either X7:1 or X7:2. If the inputs should be controlled with the same voltage level, but from two different voltage sources, having probably two different ground levels, the first neutral line should be connected to X7:1 and the second to X7:2. In this case the jumpers Wx connecting the inputs to X7:2, but controlled by the source, connected to X7:1, must be cut off. The same method is needed for the other jumpers Wx. High frequency grounding is done by 100 nF capacitor.
