8.4.33 Speed monitoring in speed control mode (P93="4")
There are 2 settings for O5 "Position reached" which are set with P227:
P227 Bit 4=1
27
Meaning / function
OM1
28
:
O5 toggles when speed is reached
O5 toggles after every new speed definition when speed is
reached.
P227 bit 4 ="0"
P14>0, small
values
(small in comparison
with the changes in
speed)
OM2
:
O5 = "1": nominal value reached and < P14
O5="1" if set point generator has finished the ramp and the
speed difference is smaller than P14.
If, after O5="1", the speed difference is again greater than P14,
then O5 = 0 until the difference is again less than P14.
P14>P15
(large in comparison
with changes in
speed)
OM3
:
O5 = "1": nominal value reached (independent of P14)
O5=1 as soon as the set point generator has reached the set
speed, and stays at "1" until the next speed change.
Functional description:
In speed control mode, P14 is given as a percentage of the set speed.
In addition, the speed is checked against the speed tolerance defined in P13.
P13 is defined in speed control mode as a percentage of the set speed and is an
absolute limit.
Speed difference > P13: error E10 is triggered
When P13=0, error E10 (and E49) can be switched off.
O5 is toggled (=changed, i.e. from O5="1" to O5="0", from O5="0" to O5="1")
following every speed change (set point generator has reached demanded speed)
In case of error (Exx is indicated), O5 remains at the current value.
Can be adjusted using:
