Mounting & Terminal Cabling Protocol

DIN-Rail Attachment

• Hook the upper module notch onto a standard 35 mm DIN rail and slide laterally into the bus coupler stack until side locks snap tightly.
• Maintain a minimum 30 mm vertical clearance above and below the housing for unrestricted air convection cooling.

MIL Wiring & Shielding Directives

• Use shielded twisted-pair cables for all line driver output channels, restricting cable run lengths to a maximum of 10 m.
• Limit auxiliary I/O cable lengths to 3 m max, ensuring continuous cable shields bond to a low-impedance functional earth ground bar.

Technical Inquiry Resolutions

• What is the maximum pulse output frequency supported by the module?

  The line driver circuit outputs differential pulse trains at a maximum speed of 4 Mpps (4,000,000 pps).

• Which pulse output modes can be configured on each channel?

  Configurations support Forward/Reverse pulse outputs, Pulse plus Direction, or Phase differential x1/x2/x4 multiplication.

• How many total physical pins are provided across the MIL connectors?

  The unit incorporates two 34-pin MIL connectors, providing a total of 68 external connection terminals.

• What are the physical cabling distance limits for the I/O signals?

  Line driver pulse output cables are rated up to 10 m max, while general auxiliary I/O lines are limited to 3 m max.

• Does the module support synchronized axis refreshing?

  Yes, the module supports both synchronous I/O refreshing and task period prioritized refreshing across the backplane.

• What types of drive amplifiers can be interfaced to this unit?

  It directly controls servo drive amplifiers or stepper motor drives that accept differential pulse train inputs.

• What is the current draw from the external I/O power supply?

  The current consumption from the external I/O power supply is 50 mA max per MIL connector interface.

• Is hot-swapping supported while the NX bus backplane is energized?

  The main power supply to the NX bus backplane must be completely switched off before removing or installing the module.
