5.2 Key Installation Traps & Avoidance Guidelines
- Trap 1: Unregulated Power Input: Direct access to unfiltered unstable mains power will cause drive overvoltage alarm and component burnout. Solution: Must match industrial power filter, strictly follow 110–480 VAC rated input range, avoid overvoltage/undervoltage operation.
- Trap 2: Non-standard Shielding Wiring: Incomplete shielding grounding or mixed wiring of power and signal cables leads to communication interference and position jitter. Solution: Separate power cables and signal cables, fully ground all shielding layers, fix shielding plates in place, avoid floating grounding.
- Trap 3: Insufficient Heat Dissipation Space: Crowded cabinet installation without reserved ventilation space causes over-temperature protection and performance attenuation. Solution: Reserve standard heat dissipation gap around the drive, ensure cabinet ventilation or external cooling equipment, ambient temperature strictly controlled below 40℃.
- Trap 4: Incorrect STO Safety Wiring: Single-channel STO wiring or wrong pin definition leads to safety function failure and non-compliant equipment. Solution: Strictly implement dual-channel wiring, verify pin assignment according to official manual, test STO on-off function after installation.
- Trap 5: Mismatched Feedback Signal Configuration: Inconsistent encoder type and software parameter settings cause motor runaway or position error.Solution: Confirm feedback type before power-on, match software protocol parameters, avoid mixed use of different specification encoders.
- Trap 6: Unregulated Tightening Torque: Excessive or insufficient terminal torque causes poor contact, heat generation and intermittent failure. Solution: Follow official recommended tightening torque for all power and signal terminals.
- Trap 7: Live Plugging and Unpowered Maintenance: Live plugging of connectors easily damages interface circuits; long-term unpowered storage causes internal capacitor aging. Solution: Cut off total power before plugging/unplugging connectors; regular power-on maintenance for long-term idle equipment.
