Please ask the sales office. * 1: When it is running at 1/5000 of the rated speed, motor may not run smoothly. When load is 100%, the speed control range become a condition of motor not to stop. When matching with NA20 series motors, speed control range will be 1:3000.
* 2: When the power-supply voltage descends, neither the declared power nor the ratings rotational speed are guaranteed.
* 3: To be changed by the power supply impedance
* 4: Please select the no fuse breaker according to the power supply caPACity with enough block capacity for protection. In regards of specifications, the mentioned values are based on the surroundings temperature 40 after our recommended heat sink is installed. The allowable radial load value is measure by the position of 20 mm from the installation surface. Each values are at the temperature of 20 to 30. The value without a/the common difference is becoming an authorized value.   Heat sink dimensions 50w, 100w 200 x 200 x T12 Aluminum plate 200w,400w 305 x 305 x T12 Aluminum plate 600w, 750w 305 x 305 x T12 Aluminum plate   Servomotor Model NA80-05 NA80-10 NA80-20 NA80-40 NA80-60 NA80-75 Rated voltage V DC24V ±10％ Quiet friction torque NmMIN 0.32 1.27 2.55 Kgf.cmMIN 3.25 13 26 Consumption power W 5 9 9.5 Release time ms MAX (20) (20) (50) Suction time ms MAX (40) (50) (80) Purpose For holding still
