The hard speed reference is a reference value which does not pass through the ramp system (Menu 2). It is added to the normal post ramp speed
reference. Its value may be written from the keypad, via serial comms, from an analog input or from an encoder input. This parameter can also be
used by the position controller (Menu 13) as the speed reference input. The hard speed reference is selected when Pr 3.23 = 1.
0, drv: Drive encoder
The position feedback from the encoder connected to the drive itself is used to derive the speed feedback for the speed controller.
1, Slot1: Solutions Module in slot 1
The position feedback from the option module in option module slot 1 is used to derive the speed feedback for the speed controller. If a position
feedback category option module is not installed in slot 1 the drive produces an Enc9 trip if the drive is active.
2, Slot2: Solutions Module in slot 2
3, Slot3: Solutions Module in slot 3
4, tACHO: Tachometer
5, ESt.SPEED: Estimated speed
Provided the setup parameters for the drive encoder are correct this parameter shows the encoder speed in rpm.
It should be noted that the value shown by this parameter is measured over a 16 ms sliding window period (in the same way as Pr 3.02 {di05, 0.40}),
and so the ripple in this parameter accessible via comms or by an Solutions Module is as defined for Pr 3.02 {di05, 0.40}. The FI attribute for this
parameter is set, and so further filtering is applied when this parameter is viewed with one of the drive keypads.
This is used in conjunction with Pr 3.29. See the description under Pr 3.29 overleaf.
