A collision detecting method for quickly securely detecting a collision between a driven body driven by a servomotor and an obstacle by using an observer, thereby preventing machine components from being damaged by the collision. An estimated distrubance torque (y) is obtained in accordance with a torque command (I) and an actual motor speed (.theta.) by means of the observer (50) formed of blocks (51 to 54) having transfer functions (Kt/J, K3, K4/S, 1/S), which depend individually on a torque constant, inertia, and parameters corresponding thereto, and a multiplier (61) having a transfer function (J.multidot.A) equivalent to the product of the inertia and a unit system conversion constant. The drive of the servomotor is stopped before any of the components of the machine is broken, in response to an alarm delivered from a comparator (62) when the estimated disturbance torque exceeds a threshold value (Ts) which is set at a value smaller than servomotor output torques corresponding to the breaking limits of the machine components.

摘要:
According to one embodiment, a magnetic disk drive includes a parameter management table, a parameter adjustment module and an interpolation module. The parameter management table stores a parameter used to write or read data to or from a disk in the parameter management table in association with each of a plurality of predetermined temperature divisions. The parameter adjustment module adjusts a first parameter stored in the parameter management table in association with a first temperature division to a second parameter adapted for the first temperature division if an ambient temperature detected by a temperature detector corresponds to the first temperature division and if the first parameter is unadjusted. The interpolation module updates an unadjusted third parameter corresponding to a third temperature division between the first temperature division and a second temperature division for which the parameter is adjusted based on a result of the adjustment of the first parameter.
