6.2.7 Behaviour in the event of inverter disable
In standard cases, the setpoint position is compared against the actual position when the
inverter is disabled. A position window can be used to control the automatic comparison
between the setpoint position and actual position in the case of a disabled inverter. In the
position window, positive and negative deviations can be set separately. If the distance
between the last setpoint position before inverter disable and the current actual position is
smaller than the parametrised value, the setpoint position keeps its last value. The setpoint
position and the actual position will be compared upon exiting this window.
If the value is set to 0 units, the setpoint position is equated with the actual position in the
case of an inverter disable. The limit value set for the upper and lower limits of the window in
the parameters must not exceed the drift of the actual position at drive standstill plus an addi-
tional safety margin.
If higher values are set, the position controller makes a jerky compensation after the inverter
is enabled. This is due to the existing system deviation.

Behaviour in case of an inverter disable during a movement
If the drive is disabled during a movement, for instance by the control word in the application
or via the STO safety function, an error is triggered.
The Resp. to inverter disable during motion parameter can be used to set a different
response.
