Hardware Installation and Configuration
You can configure the P7000 series stepper drives using the external DIP switches or with
software through the RS-232 port. If you have an NI stepper motor, you can configure the drive
and motor using only the DIP switches. If you have a third-party motor, you must use the
P7000 Tools configuration software.
Note This document assumes you have already installed your NI 9512 C Series
module and all required software to the host computer. Refer to the Getting Started
with NI 951x C Series Modules and LabVIEW, available from ni.com\manuals
and installed with the NI LabVIEW NI SoftMotion Module, for installation
information. Software installation onto the RT target is covered in Step 3: Install
Software on and Configure the NI RT Controller.

Step 1: Set Up the CompactRIO System
Complete the following steps to set up the CompactRIO hardware.
1. Install the real-time CompactRIO controller on the chassis if you are not using an integrated
controller and chassis.
Note Write down the controller serial number before installing the controller onto
the chassis. You will be unable to read the serial number after you install the
controller.
a. Make sure that no power is connected to the controller or the chassis.
b. Align the controller with the chassis as shown in Figure 2.
Figure 2. Installing the Controller on the Chassis (Eight-Slot Chassis Shown)
c. Slide the controller onto the controller slot on the chassis. Press firmly to ensure the
chassis connector and the controller connector are mated.
d. Using a number 2 Phillips screwdriver, tighten the two captive screws on the front of
the controller.

2. Connect the controller to a power supply and an Ethernet network on the same subnet as
the development computer. Refer to the controller operating instructions for information
about wiring the controller to the power supply and Ethernet network.
Note Do not plug in or turn on any power to the system until after you complete
Step 5: Connect Power to the P7000 Drive.
3. Install the NI 9512 module in slot 1, 2, 3, or 4 of the chassis.
Step 2: Connect the Stepper Motor to the Drive
Connect the stepper motor as shown in Figure 3. The NI stepper motors are highly
recommended, as they are optimized to work with the P7000 series stepper drives.
Caution Do not hot-plug the motor connector. Also, avoid “whiskers” from
stranded phase leads protruding from the motor plug.

Using Table 4 or 5, set switches S1 and S2-1 to configure the drive for your motor. If you have
a third-party motor set the switches for a third-party motor and use the serial configuration using
P7000 Tools.
For the remaining DIP switches, refer to Table 2 for the switch settings and to Table 3 for the

Step Resolution
Table 6 lists the step resolution switch settings.
Load Inertia
The P7000 series stepper drives eliminate the resonance typical of step motors with high-speed,
digital processing of motor electrical activity. To use this feature, you must set three switches
based on the load-to-rotor inertia ratio. These switches select the gain parameter the drive uses
to stabilize the motor. You can calculate the load inertia by hand or by using the Motioneering

Dynamic Smoothing
Dynamic smoothing is a temporal filter (second-order, low-pass) applied to the command
sequence to reduce jerk. It helps reduce overshoot and lessens the excitation of mechanical
resonance in the system. It filters from slightly below the resonant frequency up to well above
resonance to remove spectral content that would be misrepresented in the motor output and may
also excite other parts of the machine.
Dynamic smoothing is a very powerful feature for achieving maximum torque from the motor.
However, it is difficult to optimize and is not necessary for the vast majority of applications.
Therefore, National Instruments recommends setting both DIP switches to OFF for minimal
smoothing.
Table 8 lists the dynamic smoothing switch settings.

Current Reduction
Current reduction reduces drive and motor heating by invoking standby current reduction. When
enabled, current reduction cuts motor current to 75 percent of its commanded value 100 ms after
receipt of the last step pulse. You can adjust the reduction proportion and delay to other values
using the P7000 Tools configuration software.
When current reduction is enabled, the motor holding torque is reduced. Do not enable it for
applications that require full holding torque when the motor is stationary.
Table 9 lists the current reduction DIP switch settings.
Note Current reduction is enabled when switch S2–10 is OFF.
Multistepping
Multistepping is similar to dynamic smoothing, except it is a much more aggressive use of the
filter. Typically, it results in a filter that begins to roll off two octaves below the resonant frequency.
This is intended for use with coarse resolution (full/half-step input pulses) to smooth large steps
into a continuous train of microsteps, and may provide smoother motion depending on your motion
application. Disable multistepping if you are not using full or half step resolution.
Table 10 lists the multistepping switch settings.

Encoderless Stall Detection
The P7000 series stepper drive is uniquely designed to sense the motor shaft position at all times.
The drive monitors the commanded position and compares it to the actual position. As with any
two-phase step motor, when the shaft position and commanded position are greater than two full
steps apart, a stall is detected, and the drive faults.
Table 11 lists the encoderless stall detection switch settings.
Encoderless stall detection uses an internal motor model for stall detection. Motors listed in
Tables 4 and 5 work well with encoderless stall detection. Third-party motors may not work as
well, as the algorithm is subject to constraints. National Instruments makes no guarantees of
reliability of this feature when using third-party motors.
Step 4: Connect the NI 9512 to the P7000 Drive
Use the direct connect cable to connect the NI 9512 to the P7000 drive.
1. Connect the NI 9512 module DSUB connector to the P7000 series drive Command I/O
connector using the NI 9512-to-P7000 cable.
2. Connect the power supply to the NI 9512-to-P7000 direct connect cable Vsup inputs.
Note Refer to the Specifications section of the NI 9512 Operating Instructions and
Specifications for power supply requirements.
3. Connect the NI 9512 module MDR connector to the 37-pin terminal block using the
terminal block cable. Refer to Chapter 4, Accessory and Cable Connections, in the NI 951x
User Manual for cabling recommendations.
4. Connect the limits, feedback, and other I/O signals to the 37-pin terminal block or custom
cable.
5. Connect the drive power supply to the P7000 drive.

When connecting only the MDR connector to the terminal block, all DSUB signals on the
terminal block are no connects (NC). The following figure shows the 37-pin terminal block
pinout when connecting only the MDR connector.

Step 5: Connect Power to the P7000 Drive
Connect either AC or DC input power to your P7000 series stepper drive. If you are using the
P70360 drive, connect AC power as shown in Figure 10. Refer to Table 12 for AC power
connector pin descriptions. If you are using the P70530 drive, connect DC power as shown in
Figure 11. Refer to Table 13 for DC power connector pin descriptions.
Connecting AC Power to the P70360
Caution Do not use J7 as an on/off switch. Hot plugging damages the connector.

Figure 10. 320 VDC Bus Connection
Refer to the P70360 (AC) High Performance Micro-stepping Drive Reference Guide, available
from ni.com/manuals or from the Product Support Package CD in your kit, for 160 VDC bus
connection. This configuration is required for third-party motors with 7 to 30 mH inductance.
Connecting DC Power
Power on your DC or AC power supply. Once powered, the P7000 drive enters a configuration
mode that causes the LED to flash and the motor to audibly squeal. This is expected operation,
as the drive is measuring the motor windings to optimize its settings. Once complete, the status
LED should illuminate green. If it is not, refer to the Tips and Troubleshooting section.
