Overview — VM24 The VM24 external I/O modules act as an interface for the general-purpose programmable inputs and outputs of all the 6000 Series servo and microstepping products. The VM24 module consists of a base board and one to three SIM (single in-line module) style boards that can be inserted to provide the user with a scaleable solution for their input and output needs. • The outputs are enhanced by an undervoltage lockout circuit and a thermal shutdown protection circuit.
Specification Summary Parameter Specification Power Requirements V o ........................ User-supplied voltage that drives output circuitry. Vo does not affect input circuitry, so it is not necessary for the VM24-IN. V o Range................ 5-24VDC Vo Current.............. 144mA, plus the sum of the load currents outputs that are in sourcing mode. V i .......................... User-supplied voltage that drives input circuitry & determines switching levels for inputs.
Impedance................ 6 kΩ, minimum. Requires input current (sourcing or sinking) of 0.111mA per volt of user-supplied voltage Vi. (e.g., 1.11mA for Vi=10V). Status:.................... Check with the TIN or INFNC command. Active Level: ........... Set by 6000 Series Controller/Indexer. Default is active low, but can be changed to active high with the INLVL command. Input frequency......... 50 kHz (the maximum frequency is limited practically to 500 Hz by the 2 ms update rate of the 6000 Series.
Undervoltage Protection......... The under-voltage lockout circuit is meant to prevent the output driver from sinking or sourcing unless the user-supplied voltage Vo is between 5VDC and 24VDC. Thermal Shutdown.... The thermal shutdown protection is intended to protect the device from marginal environmental factors. It must not be considered short circuit protection.
VM24 Assembly Configurations The VM24 is available in five different configurations, as shown in the following table. Each configuration uses the same base unit. The combination of SIM boards installed in the base unit determine the I/O configuration.

Jumper Configuration The jumpers are used to configure the inputs for the I/O boards as sinking or sourcing. Each socket has its own corresponding jumper, allowing each board with inputs to be independently configured for sinking or sourcing. Sinking Inputs: Sourcing Inputs: Position 3 (shown) Jumps pull-up to Vi (pin 3) Position 1 Jumps pull-up to Ground (pin 1) The default jumper position when shipped from the factory is position 3, as shown below.
Ribbon Cable Connection Caution Remove power to the VM24 before attaching or removing the cable. The VM24 is shipped with a 2-foot ribbon cable, with mating connectors. Connectors are keyed to ensure that they are inserted into mating connectors correctly.

Output Connections Caution Remove power to the VM24 before making any connections. Connect the output pull-up pin OUT-P of the 6000 Series unit to Vo on the VM24 module to ensure the proper sequencing of output signals upon application of power to the VM24. The Output, Ground, and +5V connections between the 6000 Controller and the VM24 are made with the 50-pin ribbon cable to the J4 connector. Use an external diode when driving inductive loads.
VM24 Module Configuration Summary The VM24 is shipped with the SIM8 boards already installed. 1. Mount the VM24 module (standard DIN rail). 2. Set the jumpers to position 3 (default) for sinking inputs or to position 1 for sourcing inputs. (See page 11). 3. Connect the 50-pin ribbon cable to the I/O connector(s) of the 6000 Series Controller/Indexer (see page 12). Connect the other end of the cable to the J4 connector of the VM24 module.
2 C H A P T E R T W O Troubleshooting
Basic Troubleshooting When your system does not function properly (or as you expect it to operate), the first thing that you must do is identify and isolate the problem. When you have accomplished this, you can effectively begin to resolve the problem.
6000 Series Controller/Indexer First, verify that 6000 Series Controller/Indexer I/O is functioning properly to aid in isolating the problem. Disconnect the 50-pin ribbon cable, or just disconnect the cable from connector J4 of the VM24, before performing this test. Outputs: Use the Transfer Output Status (TOUT) command to check the status of the outputs. Use the Output State (OUT) command to change the outputs.
50-pin Ribbon Cable Next, verify that the ribbon cable is relaying the signals properly. Connect the 50-pin ribbon cable to the 6000 Series unit, but do not connect the other end of the cable to the VM24. Repeat the above test, applying and checking voltages at the connector that would plug into J4. (The red stripe on the ribbon cable corresponds to pin 50 on the 6000 Series Controller/Indexer I/0 connectors.) As an alternative, disconnect the 50-pin ribbon cable from the 6000 Series unit and the VM24.
Outputs Use the Transfer Output Status (TOUT) command to check the status of the outputs. Use the Output State (OUT) command to change the outputs. Use a voltage meter to check individual outputs at the screw terminals (J4) of the VM24 to verify that the voltage level toggles between Ground and (Vo-2). [The output level should be approximately 2 volts less than the user supplied voltage Vo.] If one output does not appear to toggle, check all other outputs. If none of the outputs will toggle, check Vo again.
P/N: SIM8-OUT PARKER COMPUMOTOR Notch Fig. 9: I/O Board and Socket To Insert I/O Boards 1. Insert the I/O board into the socket, as shown in Fig. 9 above, and in Fig. 10 below. Start the I/O board at an angle of approximately 30°. 2. Firmly press the board into the socket and rotate it forward until it snaps underneath the metal clips. 3. Make sure both clips have snapped into place to secure the I/O board. 2 1 30 Fig.
To Remove I/O Boards 1. Gently depress or push the metal socket clamps (see Fig. 11 below) to release the I/O board from the socket. 2. Tilt the I/O board toward the back of the socket and lift it out gently. Never force the I/O board out of the socket without releasing the clamps. Failure to release the clamps may break the socket, causing damage which is not covered by warranty. Depress - or - Push Fig. 11: SIM Socket Clip - Top View Caution Remove power to the VM24 before removing or inserting boards.
