Additional information from the manufacturer’s manual:
Compliance: UL/C-UR-US listed, UL file E480221 (cooling type J); standards EN 60034-1/5/6/7/11/14; class 3K3/3Z12. Life-cycle status not stated in the manual.
Rating & cooling: EN 60034-1 S1 continuous; insulation class F; cooling liquid-cooled with integrated heat exchanger, IC 3W7 (incoming coolant 10-25 degC, max. 5 K below ambient); thermal protection KTY84-130, max winding 155 degC.
Mounting per EN 60034-7: horizontal IM B5 or IM B35. FF flange per IEC; shaft end DIN 748; key DIN 6885-1 Form A; balancing DIN ISO 8821; runout DIN 42955 N; coating water-based RAL 9005; bearing life LH10 20,000 h.
Environment: class 3K3/3Z12 at 0..+40 degC (= -15..+60 degC), rel. humidity 5-85%; max. elevation 1000 m; IP54; vibration resistance radial 3 g / axial 1 g (10-55 Hz).
Shaft loads: permissible radial force per model (Fr vs speed diagrams); reinforced A-side bearing option. Noise: no motor-body sound level; liquid cooling significantly reduces noise emissions vs fan-cooled variants.
Feedback: resolver, EnDat 2.1 (ECN 1313/EQN 1325) or EnDat 2.2; encoders for functional safety available. Power via terminal box; encoder via speedtec or ITEC.
Safety: encoders support functional safety; STO implemented by ACOPOS servo drive.
