Vmax = maximum velocity of the drive
t = acceleration time
The values for Vmax and the aCceleration time may be read from the
velocity diagram for the application.
P6 — Mdbes • Vk

Mdbes = Permissible accelerating torque (Nm)
Motor = Moment of Inertia of the motor (kgm
2)
Load = Moment of lnertia of the bad (kgm2)
If there is a gear reduction, the bad moment of inertia should be reflected to the
motor shaft by dividing it by the square of the gear ratio.
Vk = Feed constant; Feed per Revolution
= Gear Reduction Ratio
Note:
The permissible accelerating torque should be determined according to the
Duty Cycle of the motor.
