ADWin DCS Control Box

There are two versions of the ADWin based control box, one based on the ADWin-Light16 processor and one based on the ADWin Gold processor.

Voltage Check for both versions:

DCS - 8 channel using ADwin-Light processor

Check that all connectors are firmly plugged in.

ADV-DCS - 8 or 16 channel using ADWin Gold processor

Outputs

The simplest place to start diagnosing the base functionality of a GDS ADWin based Dynamic System is to use the ADWin Test v1.2 software, which is a piece of GDS debugging software, in conjunction with a good quality Multimeter to measure the Control voltages and the Digital Input and Output signal voltages.

GDS ADWin Test v1.2 allow debuggging of all of the data acquisition channel values, encoder values, VCS control Signals, Digital Outputs and Digital Inputs.

Open GDS_ADwin_Test.exe and select the relevant Tab for your Dynamic System (MINIDYN / EMDCSS / MAXIDYN/HCA).

The first place to check that the hardware is receiving the digital input signals from the control system, and is sending back the digital output signals to the control system is on the MD Intercon PCB (see photo below) inside the dynamic system. There is one of these PCB’s per dynamic axialaxis. Therefore a MINIDYN will have one and an EMDCSS/HCA will have two. The digital outputs are the signals that are sent to the dynamic system by the control system to instruct the dynamic system to enable the motor drives and other functionality.

First check that the +5V, +12V and -12V LED lights are illuminated. If they are not all illuminated the use a Multimeter to check the voltages on the connection block on the bottom of the PCB. Place the Black probe on the 0V terminal. Then with Red probe check the +5V, +12V and -12V are giving those voltages respectively.

Next individually set each one of the Digital Outputs using GDS ADWin Test and check the corresponding signal on the MD Intercon PCB. On the appropriate Tab in the software corresponding to your hardware click on Start Process.

To test a Digital Output place the Black probe of the Multimeter on the 0V loop at the top right of the MD Intercon PCB, and place the Red probe on the relevant Digital Output number (see table below).

• Place the Red probe on the FAC Bit (Disable Forward Movement) on the MD Intercon PCB (bit 2). The voltage measured should be 0V. Now tick the Forward Disabled (Axis 1 for an EMDCSS/HCA - Axis 1 is the Vertical Axis) Digital Output in the GDS ADWin Test software (see below). The voltage measured should be 5V.

• Place the Red probe on the RAC Bit (bit 3). The voltage measured should be 0V. Now tick the Reverse Disabled Digital Output in the GDS ADWin Test software (see below). The voltage measured should be 5V.

• Place the Red probe on the Enable DIO Bit (bit 4). The voltage measured should be 0V. Now tick the Enable DIO Digital Output in the GDS ADWin Test software (see below). The voltage measured should be 5V. Before ticking Enable DIO the motor belts should be free to turn by hand. Once Enable DIO has been ticked the motor should be energised and be locked from turning by hand by the control voltage and the FAC and RAC Digital Outputs.

• If the system has a second dynamic axis (EMDCSS/HCA/MAXIDYN) then repeat this process for the MD Intercon PCB for the second dynamic axis. Note: If the second dynamic axis is the rotational of an HCA then there is too much friction in the 40:1 gearbox to turn the motor belt by hand when Enable DIO is unticked.

Digital Inputs

The the digital inputs are the signal sent by the dynamic system back to the control system to report it’s current state and if any problems/errors exist.

To test a Digital Inputs place the Black probe of the Multimeter on the 0V loop at the top right of the MD Intercon PCB, and place the Red probe on the relevant Digital Output number (see table below).

Ensure that the Enable DIO Digital Output for the Axis to be tested is Unticked.

• Place the Red probe on the FWD Limit Switch Bit on the MD Intercon PCB (bit 8). The voltage measured should be 0V. Now manually press in the Forward (upper) Software Limit switch until you hear a click. In the GDS ADWin Test software the Forward Limit (Axis 1) indicator should come on. The voltage measured should be 5V.
