Model Suffix Decoding — NA:

• N = No brake
• A = Natural convection cooling

Key Features:

• Standard-length S712 variant — balanced torque and speed
• Resolver feedback — immune to EMI, suitable for harsh environments
• High continuous torque for large machine axes
• No brake — requires external brake for vertical hold

Applicable Industries: Heavy machine tools, press machines, large conveyors, printing presses, metalworking equipment

Installation Requirements:

• Mount using B5 flange or B35 foot+flange
• Bolt torque: 60 Nm (M10)
• Coupling alignment: ≤ 0.03 mm TIR, angular ≤ 0.1°
• Resolver cable: shielded twisted pair, max 30 m

Usage Notes:

• Do not operate above 3500 RPM
• Continuous torque above 80% rated requires derating or forced cooling
• Resolver excitation: 10 Vrms, 10 kHz (provided by drive)
• Do not subject to axial loads > 150 N
• Verify phase resistance matches drive settings before energizing
