  • Page 4: Overview

    1 — OVERVIEW OVERVIEW The Curtis 1352 eXm expansion module provides a simple, flexible, and low- cost method for adding additional and specialized I/O to a system. The eXm utilizes the popular CANopen communication bus for all control, status, and setup.
  • Page 5 The eXm can add a programmable level of dither to the PWM output. This keeps the seals of a proportional valve oiled, allowing the valve to move freely for accurate PV control. Dither is only active on drivers in Constant Current mode. Curtis 1352 eXm Manual, Rev. D...
  • Page 6 Each output can be also be used as a digital input. Each input is digitally filtered to eliminate switch “bounce” or noise in the signal. The eXm has internal resistor pull-downs to B– to provide active high to B+ inputs (standard Curtis input format). The inputs utilize Schmidt Trigger logic to provide signal hysteresis, further improving noise immunity and reducing faulty readings.

  • Page 7: Installation And Wiring

    INSTALLATION AND WIRING MOUNTING THE MODULE The outline and mounting hole dimensions for the 1352 eXm module are shown in Figure 2. The module should be mounted using two #10 or M5 screws. Care should be taken to prevent contaminating the connector area C A U T I O N before the mating 14-pin connector is installed.
  • Page 8 EMC performance complies with applicable regulations; suggestions are presented in Appendix A. The 1352 eXm contains ESD-sensitive components. Use appropriate precautions in connecting, disconnecting, and handling the module. See instal- lation suggestions in Appendix A for protecting the module from ESD damage.

  • Page 16: Canopen Communications

    The eXm adheres to the industry standard CANopen communication protocol and thus will easily connect into many CAN systems, including those using the Curtis AC and Vehicle System controllers (1234/36/38, 1298, and 1310). Any CANopen-compatible master can be programmed to control the eXm.

  • Page 18: Nmt Messages

    (FFXXh) per DS301. Therefore the upper byte is FFh when a fault is present, and the lower byte is equal to the Curtis fault code. When no faults are present and/or the last fault has just been cleared, the emergency message will use the error code value of 0000h.

  • Page 20: Pdo Communications

    PDO incoming at any rate without faulting. Take care using this setting as the last PDO commands will stay on the eXm indefinitely. The 1352's PDO-TX (MISO) can also be set to cyclical transmission every 4ms to 1000ms rate as soon as the eXm put in Operational Mode. Finally, the PDO-TX (MISO) can be set to one of 5 types.
