6.6.9.6 Reference Freeze (Menu Index 5.8.5)
This feature makes it possible to freeze the active reference by a digital input to the actual output speed and to increase/decrease the
reference by using 2 other digital inputs. Additionally, independent ramp times, delays, and speed steps can be configured.
When enabling the freeze reference feature, the reference is frozen to the actual output. If this reference is out of the allowed speed
range, the frozen reference is set to the closest speed limit. After starting up or after cycling the power of the drive, the reference for the
freeze feature is set to either the last freeze reference or to the minimum speed of the drive. See parameter 5.8.5.7 Freeze Initialization.
When reaching the upper speed limit or the lower speed limit of the drive, the freeze reference is not further increased or decreased
in the limited direction. If the drive is configured for both rotation directions and a minimum speed has been defined, the reference
bypasses the area between the positive and the negative minimum speed while Freeze Up or Freeze Down are used.
