Horizontal and vertical upward

Vertical downward

[ZM] = h-1

Permitted switching frequency of the motor

[Z0] = h-1

No-load starting frequency of the motor with brake

[KJ] = 1

Factor for external mass moment of inertia

[KM] = 1

Factor for load torque

[KP] = 1

Factor for static power and relative cyclic duration factor
