Product Introduction
This unit is a dedicated single-axis motion coprocessor for Series 90-30 control systems. It executes acceleration/deceleration profiles, homing routines and electronic gearing locally without burdening the main PLC CPU.
In follower mode, the axis can synchronize to an external master encoder signal for cutting, winding and printing machinery. All motion parameters and program sequences are configured via programming software. Multiple modules can be installed in one rack to expand total axis count. It is widely used on single-axis machine retrofits.
QA & Testing SOP (Transparency Building)
- Incoming Inspection: Verify part marking. Inspect backplane edge pins for bending or corrosion; examine D-Sub motion connectors and housing for physical damage.
- Live Testing: Mount into validated Series 90-30 rack, apply rack power. Download motion configuration, simulate encoder feedback and verify axis trajectory execution over a continuous 24-hour test cycle.
- Electrical Testing: Use Fluke 115 to monitor backplane 5VDC rail stability. Insulation resistance testing must exceed 10MΩ between field terminals and chassis protective ground.
- Firmware/Config Backup: Record onboard module firmware version. Photograph front panel labels and connector pin layout before erasing resident motion programs.
- Final QC & Packaging: Place unit inside anti-static shielding. Attach dated QC test tag confirming motion profile execution and encoder interface validation prior to shipment.
Installation Pitfalls & Guide (Engineer to Engineer)
❗ No Hot Swap Support: Series 90-30 backplanes lack hot-swap bus logic. Live removal disrupts all rack operation and risks permanent backplane trace damage. Full rack power shutdown mandatory. ❗ Wiring Pinout Risk: Servo encoder and command wiring uses proprietary GE pinout. Generic cables lead to loss of feedback or axis runaway. Use validated GE motion cables. ❗ Follower Mode Noise Susceptibility: Master encoder wiring must be routed separately from high-power cables to avoid synchronization jitter. ❗ ESD Dangers: Un-grounded handling damages encoder receivers and motion logic circuits. Static faults manifest as position drift or intermittent axis faults after commissioning. ❗ Power Budget Oversight: Include the module’s 340mA @5VDC load when calculating total rack power consumption to avoid power supply voltage sag. ❗ Module Quantity Limit: Respect per-CPU and per-baseplate APM installation limits; exceeding limits causes backplane communication bandwidth overload.
Replacement Guide:
- Pre-install: Activate lockout-tagout on rack power; back up full hardware configuration and motion programs. Photograph all motion D-Sub wiring connections.
- Removal: Unplug motion cables, unlatch module and slide straight out without twisting backplane connectors.
- Install: Seat new unit fully into vacant slot, lock latches, reconnect D-Sub motion cabling.
- Power-on Test: Restore rack power, confirm OK LED status, download saved motion configuration, execute homing and positioning cycles and verify no axis fault alarms.
FAQ (Frequently Asked Questions)
Q: Does this module support hot swapping? A: No. Series 90-30 architecture does not implement hot-swap functionality. Complete rack power shutdown is required before removing or installing the unit.
Q: What is the core difference between and IC693APU302? A: = single-axis motion module. IC693APU302 / 302P = dual-axis motion module. They are mechanically interchangeable but cannot substitute for each other without program and machine wiring modifications.
Q: Can this module be installed inside PACSystem RX3i racks? A: No. Form factor, backplane signaling and firmware are exclusive to Series 90-30 chassis. It cannot operate within RX3i systems.
Q: Does this module support stepper drives? A: It interfaces with differential pulse/direction servo drives. Direct stepper compatibility depends on drive signal interface; external signal conditioning may be required.
Q: Can the axis operate in follower mode while executing independent positioning sequences? A: Yes. The axis can switch between standard positioning and electronic gearing mode via PLC command.
Q: Will saved motion configuration download directly onto a replacement unit? A: Motion program logic imports without modification. Homing offsets, gear ratios and fault thresholds should be verified after replacement. Always execute a full machine homing sequence.
Q: Can multiple modules be installed in one rack? A: Yes, subject to the CPU type limits. Multiple single-axis modules can be combined to achieve multi-axis machine control.
