Short Description

Systemwide Definition of Velocity / Speed

Description

VUNIT gives the systemwide definition of velocity / speed resolution. This parameter effects all parameters that are related to velocity of the velocity controller and speed of the position controller.

VUNIT = 0 gives velocity in RPM and speed in µm/sec. This setting is equal to the firmware < 4.00.

Remark:

  1. All parameters that are related to velovity have a fixed format of 32 Bit with 3 fractional digits. This causes a problem with some of the VUNIT settings (especially VUNIT=6), related to the resolution of the position controller (PGEARI), that not the full range of speed can be used. Under this condition, a different setting of VUNIT is necessary.
  2. All parameters that are related to speed have a fixed format of 32 Bit with no fractional digits. This causes a problem with some of the VUNIT settings (especially VUNIT=3) to give fractional digits. Under this condition, a different setting of VUNIT is necessary.
