GE IC697HSC700

Product Introduction

The GE IC697HSC700 is a 2-channel high-precision high-speed counter module in GE’s Series 90-70 PLC family, engineered as the “motion parameter sensing core”—converting high-frequency pulse signals from incremental encoders into actionable position, speed, and count data for Series 90-70 CPUs. Unlike the discrete state-focused IC697MDL350 digital input module, the IC697HSC700 specializes in “high-bandwidth motion monitoring”: it processes 1 MHz pulse signals with 4x quadrature decoding (equivalent to 4 MHz effective resolution) per channel, enabling sub-millimeter positioning accuracy in industrial motion systems.

Technical positioning for precision manufacturing and motion control (e.g., CNC machine tool spindles, automated guided vehicles (AGVs), high-speed packaging lines), the IC697HSC700 retains Series 90-70’s industrial-grade reliability: differential signal input resists electromagnetic interference from motor drives , while 2500V AC optical isolation prevents backplane signal crosstalk. It pairs seamlessly with Series 90-70 components—powered by IC697PWR720 (high-capacity power supply) and controlled by IC697CPU770 (high-performance CPU)—acting as the “motion feedback hub” in automation architectures. For dual-axis systems (e.g., X/Y table positioning), it eliminates the need for two single-channel counter modules, reducing chassis slot usage by 50%.

Core Advantages and Technical Highlights

1 MHz High-Frequency Processing for Precision Motion: The IC697HSC700’s 1 MHz counting frequency with 4x decoding captures 4 million position increments per second. In a CNC milling machine using a 1024-line encoder, the module resolves positional changes as small as 0.00035° (360°/1024 lines/4x decoding)—enabling surface finish accuracy of Ra 0.4 μm, a 60% improvement over 250 kHz counter modules.

Dual-Channel Independent Operation for Multi-Axis Control: Two isolated channels support simultaneous monitoring of dual motion axes. An AGV navigation system tracking both X (lateral) and Y (longitudinal) axis encoders uses one IC697HSC700 instead of two single-channel modules—simplifying wiring by 40% and reducing CPU communication latency by 30%.

Programmable Compare Triggers for Real-Time Control: 4 configurable compare values per channel enable event-driven actions without CPU intervention. A high-speed packaging line uses compare triggers to activate sealers (at 500 mm position) and ejectors (at 1000 mm position)—reducing trigger delay to ≤1 μs versus software-based control (≥10 ms).

Differential Input for Noise Immunity: RS422 differential signaling rejects common-mode interference from welding equipment or VFDs . In a metal stamping plant, the module maintains stable counting even with 30V AC noise on signal cables—error rate drops from 2% (single-ended input) to 0.01%.

Typical Application Scenarios

In CNC machine tool spindle positioning, the IC697HSC700 (installed in IC697CHS750 10-slot chassis) connects to two 1024-line incremental encoders (spindle and feed axis). Controlled by IC697CPU770, it sends real-time position data to IC697MDL760 VFD module—adjusting spindle speed within 1 ms of position 偏差. 1 MHz counting ensures tool change positioning error <0.1 mm, preventing workpiece scrap.

For high-speed packaging lines, the IC697HSC700 monitors a 5000-line encoder on a 300 m/min conveyor. Paired with IC697CPM915 CPU, it triggers IC697MDL751 solid-state outputs at pre-set positions (e.g., 200 mm for label application, 500 mm for cutting). Compare triggers reduce packaging cycle time by 15% versus CPU-based timing.

In elevator traction control, the IC697HSC700 tracks an encoder on the elevator motor (1000 lines/revolution). Installed in IC697CHS730 chassis, it works with IC697CPU731 to calculate speed (via pulse interval measurement) and position—stopping accuracy improves to ±5 mm, meeting EN 81-20 safety standards. Z-phase zero mark resets the counter at each floor, eliminating cumulative error.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Power off the chassis (e.g., IC697CHS750) and verify CPU compatibility (IC697CPU770 recommended for 1 MHz operation). Required tools: anti-static wristband, torque screwdriver (0.8–1.2 N·m), wire strippers (24–20 AWG), and oscilloscope (for signal verification). Clean slot contacts with lint-free cloth.

Installation and wiring: Align the module with chassis rails, push until latched, and secure with screws. Wire encoders using shielded differential cable : Channel 1 (A1+, A1-, B1+, B1-, Z1+) to encoder A/B/Z signals; Channel 2 similarly. Connect shield to chassis ground (single-point grounding). External encoder power (5–15V DC) must be isolated from chassis power.

Commissioning and maintenance: Power on the chassis, use Proficy Machine Edition to configure counting mode (e.g., quadrature 4x) and compare values. Test with encoder: rotate 1 revolution—confirm counter increments by 4096 (1024-line encoder ×4). Verify compare output triggers at set values. Daily maintenance: check channel LEDs (green = signal present). Every 12 months: test isolation resistance (≥100 MΩ @ 500 V DC) and signal integrity (oscilloscope check for pulse distortion). Replace if fault LED persists or counting error >0.1%.

Service and Guarantee Commitment

The GE IC697HSC700 includes a 1-year manufacturer’s warranty (consistent with Series 90-70 special function modules) covering material defects (differential receivers, isolation circuits) and workmanship. GE provides 24/7 technical support via phone/email, with engineers specializing in motion control to assist with encoder compatibility and trigger configuration.

Beyond warranty, GE offers on-site calibration and repair services. Global service centers stock genuine spare parts (signal processing chips, isolation modules), ensuring 2–3 business days delivery for urgent replacements. Each module undergoes 100% factory testing—validating counting accuracy (±1 pulse at 1 MHz), isolation, and surge protection—to meet precision manufacturing and motion control industry standards.
