1 General information about the data provided in this catalogue General Definitions Outputs, torques and speeds The outputs, torques and speeds specified in the catalogue are rounded values and apply to: ˘ Operating time/day = 8 h (100% OT) ˘ Duty class I for up to 10 switching operations/h ˘ Mounting positions and designs in this catalogue ˘ Standard lubricant ˘ f mains = 50 Hz constant ˘ T amb = 20°C for gearbox 40°C for motors (in accordance with EN 60034) ˘ Site altitude < = 1000 m amsl ˘ The selection tables provide the permissible mechanical powers and torques. For notes on the thermal power limit, see page 2-2. ˘ The rated power specified for motors and geared motors applies to operating mode S1 (in accordance with EN 60034). Under different operating conditions, the values obtained may vary from those listed here. In the case of extreme operating conditions, please consult your Lenze sales office. Load capacity c of gearbox Characteristic value for the load capacity of Lenze geared motors. ˘ c is the ratio of the permissible rated torque of the gearbox to the rated torque delivered by the drive component (e.g. the integrated Lenze motor). ˘ c must always be greater than the application factor k determined for the application. Application factor k (corresponding to DIN 3990) Takes account of the effect of any loads that are actually present and that vary during the anticipated operating time of gearboxes and geared motors. k depends on ˘ The type of load ˘ The load intensity ˘ Temporal influences 1-10 G-motion atex en 7/2006
