REVEHYST (P99)
This parameter is used to be able to control when the compensation should really be applied after
detecting a movement reversal and not applying it every time a reversal command is received.
This a.m.p. should be set with the value that the position must vary after the first movement reversal
(hysteresis) so it is considered that the command to compensate has been issued, hence prevent
it from issuing the compensations every time it receives the command to reverse the moving
direction if that margin has not been exceeded. The value entered in this parameter must be in mm
for linear axes and in degrees for rotary axes. Default value 0.0000.
Example
If REVEHYST= 5 dµm, the CNC will not activate the reversal compensation in all the reversals after
the first one as long as the position does not change at least a value equal to the setting of a.m.p.
REVEHYST since the first command to reverse the position command was issued.
In other words, if a reversal command is sent when the position command has varied 2 dµm from
the position where the first reversal command took place, it does not issue the compensation (it has
not exceeded the value given by a.mp. REVHYST) and it just reverses the movement.
Only when the position command variation reaches 5 dµm, it will issue the compensation and the
next command to reverse will be taken as the new reference for evaluating the position variation to
determine when it reaches the value given in a.m.p. REVEHYST again and it compensates for it
again.
Considerations
•
Being a.m.p. REVEHYST (P99) =0, the backlash compensation by reversal peak or backlash
will always be applied in each reversal.
•
Having set a.m.p. REVEHYST (P99) with a value other than 0, to set a.m.p. PEAKDISP (P14)
to cut the backlash peak, we recommend to use a smaller REVEHYST value than that of
PEAKDISP so as not to apply the backlash peak.
•
If they have been set as DRO axes, the value of a.m.p. BACKLASH (P14) will be taken into
account for these axes. In these cases, especially if they have sinusoidal feedback, we
recommend to use a value of a.m.p. REVEHYST (P99) other than 0 in order to apply backlash
compensation.
