Characteristics: Tr20 worm screw, pitch 4 (1 handwheel turn = 4 linear mm) or M20 worm screw, pitch 2.5 (1 handwheel turn = 2.5 linear mm). Positioning accuracy: ±0.3 mm/300mm*. Operation: STEP-BY-STEP (NO continuous operation). Max. 120 rpm; max time: 1 (min; on/off ratio=1/10 (max 10%). Millimetre scale marking p. . WARNINGS * the ACCURACY indicated is theoretical. Accuracy levels depend on the actual conditions of use and are affected by the accuracies of the kinematic chain - consisting of the handwheel/crank handle/revolution counter kit or any connection joints - and by the performance of the position control system (encoder, etc.).
