This migration requires designated conversion cables for both the high-resolution encoder line and the main power connector due to differences in physical terminal sizing and pinouts.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eOperating this motor at continuous high duty cycles requires adequate heat dissipation. Ensure it is bolted to a steel or aluminum mounting flange of at least 400 mm x 400 mm x 20 mm to prevent thermal alarms on the drive. For vertical applications, avoid using this standard model; instead, deploy the brake-equipped variant (HF-SP702B) to prevent load drop during emergency stops or power failures.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo eliminate electromagnetic interference (EMI) issues with high-resolution feedback signals, ensure the encoder cable shield is grounded directly to the amplifier cabinet's main backplate. Power cables carrying the high-frequency PWM drive outputs must be routed separately from sensor and control lines, maintaining a minimum physical clearance of 30 cm.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 15px; margin-bottom: 1.5rem; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Verify that all incoming three-phase AC power sources are completely locked out and tagged out before beginning the installation process.
