15. USING A DIRECT DRIVE MOTOR
15 - 19
(1) Dynamic brake operation
(a) Calculation of coasting distance
Fig. 15.3 shows the pattern in which the servo motor comes to a stop when the dynamic brake is
operated. Use equation 15.1 to calculate an approximate coasting distance to a stop. The dynamic
brake time constant IJ varies with the direct drive motor and machine operation speeds. (Refer to (1)
(b) of this section.)
