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.
Special Conditions for Hazardous Locations Use in

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.
