Figure 9-28: Example of Actual Value Signal Scaling
2.9.9 PID error value inversion ID340
This parameter allows you to invert the error value of the PID controller (and thus the
operation of the PID controller).
0 No inversion
1 Inverted
2.9.10 Sleep frequency ID1016
The drive is stopped automatically if the frequency of the drive falls below the Sleep
level defined with this parameter for a time greater than that determined by
parameter 2.9.11. During the Stop state, the PID controller is operating switching the
drive to Run state when the actual value signal either falls below or exceeds (see par.
2.9.13) the Wake-up level determined by parameter 2.9.12. See Figure 9-29.
2.9.11 Sleep delay ID1017
The minimum amount of time the frequency has to remain below the Sleep level
before the drive is stopped. See Figure 9-29.
2.9.12 Wake-up level ID1018
The wake-up level defines the frequency below which the actual value must fall or
which has to be exceeded before the Run state of the drive is restored. See Figure
9-29.
2.9.13 Wake-up function ID1019
This parameter defines if the restoration of the Run state occurs when the actual
value signal falls below or exceeds the Wake-up level (par. 2.9.12). See Figure 9-29.
