Safety Guidelines for Hazardous Locations

The NI 9514 is suitable for use in Class I, Division 2, Groups A, B,

C, D, T4 hazardous locations; Class I, Zone 2, AEx nA IIC T4 and

Ex nA IIC T4 hazardous locations; and nonhazardous locations

only. Follow these guidelines if you are installing the NI 9514 in a

potentially explosive environment. Not following these guidelines

may result in serious injury or death.

Caution Do not disconnect I/O-side wires or connectors

unless power has been switched off or the area is known to

be nonhazardous.

Caution Do not remove modules unless power has been

switched off or the area is known to be nonhazardous.

Caution Substitution of components may impair

suitability for Class I, Division 2.

Caution For Division 2 and Zone 2 applications, install

the system in an enclosure rated to at least IP 54 as defined

by IEC/EN 60079-15.

4|ni.com |NI 9514Operating Instructions and Specifications

Caution For Division 2 and Zone 2 applications, install a

protection device between the input signal and the Vsup

pin. The device must prevent the Vsup-to-channel voltage

from exceeding 42 V if there is a transient overvoltage

condition.

suitable for use in Zone 2 hazardous locations, in ambient

temperatures of – 40 °C Ta 70 °C. If you are using the NI 9514

in Gas Group IIC hazardous locations, you must use the device in

an NI chassis that has been evaluated as Ex nC IIC T4, Ex IIC T4,

Ex nA IIC T4, or Ex nL IIC T4 equipment.

Caution You must make sure that transient disturbances

do not exceed 140% of the rated voltage.

Caution The system shall only be used in an area of not

more than Pollution Degree 2, as defined in IEC 60664-1.

degradation, install and use this product in strict accordance with

the instructions in the product documentation.

Furthermore, any changes or modifications to the product not

expressly approved by National Instruments could void your

authority to operate it under your local regulatory rules.

Caution To ensure compliance with the applicable

regulatory requirements, product installation requires

either special considerations or user-installed, add-on

devices. See the product installation instructions for

further information.

Caution The inputs/outputs of this product can be

damaged if subjected to Electrostatic Discharge (ESD). To

prevent damage, industry-standard ESD prevention

measures must be employed during installation,

maintenance, and operation.

Special Guidelines for Marine Applications

Some products are Lloyd’s Register (LR) Type Approved for

marine (shipboard) applications. To verify Lloyd’s Register

certification for a product, visit ni.com/certification and

NI 9514 Operating Instructions and Specifications |© National Instruments |7

search for the LR certificate, or look for the Lloyd’s Register mark

on the product label.

Caution In order to meet the EMC requirements for

marine applications, install the product in a shielded

enclosure with shielded and/or filtered power and

input/output ports. In addition, take precautions when

designing, selecting, and installing measurement probes

and cables to ensure that the desired EMC performance is

attained.

Connecting the NI 9514

The NI 9514 servo drive interface module is part of a family of

C Series motion modules. The module provides servo drive

interface signals for a single axis, a full set of motion I/O including

inputs for a home switch and limit switches, incremental encoder

inputs for position feedback, and 0 to 30 V digital input lines. The

NI 9514 also includes a processor to run the spline interpolation

engine and PID control loop. Working together they produce

smoother motion resulting in precise servo motion control.

System Connection

The NI 9514 has two connectors, a 15-pin DSUB drive interface

connector and a 20-pin MDR feedback connector. The 15-pin

DSUB includes command signals for interfacing with servo

amplifiers or drives, a 0 to 30 V general-purpose digital input line,

and a 19 to 30 V input for power connection. Refer to Table 1 for

the DSUB connector pin assignments.

Note The remainder of this document does not

distinguish between drives and amplifiers. All

references to drives also apply to amplifiers.

The 20-pin MDR connector includes incremental encoder

feedback inputs, a +5 V output for encoder power, home, limit,

and position compare inputs, an output for position compare, an

additional 19 to 30 V input for power connection, and an additional

0 to 30 V general-purpose digital input line. Refer to Figure 2 for

the MDR connector pin assignments.

Note The NI 9514 requires an external power supply.

You can connect the external power supply to the Vsup

input provided on the DSUB or MDR connector. Do not

connect more than one external power supply to the

module.

NI 9514 Connection Options

National Instruments offers several options for connecting the

NI 9514 to servo drives. You can use the NI 9514/16 to AKD cable

to connect the NI 9514 to the AKD analog servo drive and AKM

series servo motors from NI. To connect to third-party servo drives

use the NI 951x Cable and Terminal Block Bundle. Refer to

Figure 3 for the 37-pin terminal block pin assignments. Refer to the

NI 951x User Manual, which you can download from ni.com/

manuals, for information about additional connection accessories

and cabling recommendations.

Tip NI offers AKD analog servo drives and matched

servo motors. Refer to Getting Started with NI 9514/16

C Series Drive Interface Modules and AKD Analog Servo

Drives for installation and configuration information.
