Product Overview

The IC695PMM335 is a multi-axis motion controller from the PACSystem RX3i platform. Emerson Automation now owns this product line. GE Intelligent Platforms (GE Fanuc) originally manufactured this module. The IC695PMM335 mounts to any RX3i universal backplane. This controller handles up to 4 servo axes simultaneously. Virtual or time-based axes can also be configured. Position, velocity, and torque loops run on the FANUC Serial Servo Bus (FSSB). Fiber optic communication achieves 50Mb/s speeds. The module includes built-in discrete I/O on its faceplate. For large systems, up to 8 modules occupy one RX3i rack. Consequently, a single rack controls up to 40 motion axes.

Motion Control Capabilities

The IC695PMM335 executes three independent control loops with impressive speed. Position loop updates every 500 microseconds. Velocity loop updates every 125 microseconds via FSSB. Torque loop updates every 62.5 microseconds via FSSB. Motion path planning runs every 1 millisecond. Floating point math supports complex motion trajectories. High-speed position capture uses 2 inputs per axis. Electronic CAM profiles are fully configurable. The built-in cam editor within Proficy Machine Edition software creates these profiles. Alternatively, you can import CSV files for custom cam shapes.

FANUC Serial Servo Bus (FSSB) Interface

Fiber optic cabling connects the IC695PMM335 to servo drives and motors. Communication speed reaches 50 Mb/s for real-time control. Cable length between nodes extends to 100 meters. Total cable length per module reaches 400 meters. Consequently, distributed machine layouts work perfectly. Noise immunity from fiber optics exceeds copper solutions. The FSSB interface reduces wiring complexity dramatically. One fiber pair replaces dozens of analog and encoder wires.

Built-In I/O Details

The IC695PMM335 includes 8 built-in I/O points on its faceplate. Four general purpose inputs accept 24VDC signals. Optical isolation protects the controller from field noise. These inputs configure for either source or sink wiring. Two high-speed inputs handle faster signal transitions. General purpose I/O points (2 total) configure as inputs or outputs. All I/O runs at 24VDC with flexible wiring. For this reason, many applications avoid separate I/O modules. Limit switches, home sensors, and drive enables connect directly.

Software & Programming Support

Proficy Machine Edition software configures the IC695PMM335. Data logging uploads and displays through this same package. PLCopen specifications guide the motion function blocks. Three interrupt routines per module handle time-critical events. Diagnostic logic blocks aid troubleshooting. Electronic CAM profiles are created using the integral cam editor. Runtime data logging captures performance metrics. For advanced automation, the IC695PMM335 unifies motion and logic seamlessly.

Installation Guidelines

Follow these steps for proper installation of the IC695PMM335.

1. Power down the RX3i rack completely before handling any modules.

2. Select an empty universal backplane slot for the controller.

3. Align the module with the upper and lower card guides.

4. Slide the IC695PMM335 firmly into place until the connectors seat fully.

5. Secure the module using the retaining screws at top and bottom.

6. Connect fiber optic cables to the FSSB ports. Observe TX/RX orientation carefully.

7. Wire built-in I/O to the faceplate terminals according to source or sink configuration.

8. Power up the system and configure the module using Proficy Machine Edition.

Note: The IC695PMM335 requires a universal backplane. Standard VME backplanes do not support this module. Verify your RX3i rack part number before installation.

Common FAQs

1. How many IC695PMM335 modules can I install in one RX3i rack?

Up to 8 modules fit in a single RX3i rack. Each module controls 4 axes. Therefore, maximum axes per rack reaches 40. The universal backplane provides sufficient power and bandwidth for full configurations.

2. What encoder types work with the IC695PMM335?

This module supports both incremental and absolute serial encoders. FSSB communication carries encoder data back to the controller. For absolute encoders, battery backup retains position after power loss. Consult the user manual for specific encoder model compatibility.

3. What is the maximum FSSB cable length for the IC695PMM335?

Distance between two FSSB nodes reaches 100 meters maximum. Total cable length per module reaches 400 meters. For example, you can daisy-chain four drives with 100 meter segments. Fiber optic cables maintain signal integrity over these distances.

4. Does the IC695PMM335 support electronic CAM profiles?

Yes, electronic CAM profiles are fully supported. Create profiles using the integral cam editor in Proficy Machine Edition. Alternatively, import CSV files with custom cam tables. Up to 3 interrupt routines per module handle CAM synchronization events.

5. What is the difference between the general purpose inputs and high-speed inputs on the IC695PMM335?

General purpose inputs handle standard limit switches and pushbuttons. High-speed inputs capture fast position events. Each axis uses 2 high-speed inputs for position capture. Response time for high-speed inputs is significantly shorter. Consequently, registration and mark sensing applications use the high-speed inputs exclusively.
