Parameterizing the NC axis

Parameter "Reference Velocity"

Parameterizing the NC axis 1:

Unit: °/s
Factory setting: 2200dec

Calculate the "Reference Velocity" using this formula:

 

Parameterizing the NC axis 2:

nref: "Reference Velocity" [°/s]

fmax: "Speed range" [full steps/s]

φ: Step angle of the motor [°]

Example for an AS1050-0120 motor:

 

Parameterizing the NC axis 3:

Setting the acceleration time

In order to pass through any resonances that may occur as quickly as possible, the ramps for the acceleration time and the deceleration time should be as steep as possible.

Parameterizing the NC axis 4:

Note

Short braking times can lead to overvoltages in the DC link.

In the event of an overvoltage in the DC link, a protective mechanism switches off the motor output stage. The "Error" status bit in the process data object STM status is set.

  • Check whether impermissibly high voltages occur in the DC link during braking.
  • If necessary, use EP9576-1032 to prevent overvoltages in the DC link.
    EP9576-1032 contains a brake resistor to dissipate drive-related overvoltages.
