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 = V0 • (0.03 + M • (A + B • V02))
Lmax: Coasting distance of the machine [m]
V0: Speed when the brake is activated [m/s]
M: Full mass of the moving part [kg]
A: Coefficient (Refer to the following table.)
B: Coefficient (Refer to the following table.)
Permissible load to motor mass ratio when the dynamic brake is
used
