Dynamic Brake Characteristics - Mitsubishi Electric MELSERVO-JET User Manual

Dynamic brake characteristics

The approximate coasting distance from when the dynamic brake is activated until when the linear servo motor stops can be
calculated with the equation below.
Lmax = V • (0.03 + M • (A + B • V
0
Lmax: Coasting distance of the machine [m]
V : Speed when the brake is activated [m/s]
0
M: Full mass of the moving part [kg]
A: Coefficient (Refer to the following table.)
B: Coefficient (Refer to the following table.)
