Actual signals and parameters 281
4025 WAKE-UP DEV Defines the wake-up deviation for the sleep function. The
drive wakes up if the process actual value deviation from
the PID reference value exceeds the set wake-up deviation
(
4025 ) longer than the wake-up delay ( 4026 ). Wake-up level
depends on parameter 4005 ERROR VALUE INV settings.
If parameter 4005 is set to 0:
Wake-up level = PID reference ( 4010 ) - Wake-up deviation
( 4025 ).
If parameter 4005 is set to 1:
Wake-up level = PID reference ( 4010 ) + Wake-up deviation
( 4025 )

4027 PID 1 PARAM
SET
Defines the source from which the drive reads the signal
that selects between PID parameter set 1 and 2.
PID parameter set 1 is defined by parameters
4001 … 4026 .
PID parameter set 2 is defined by parameters 4101 … 4126 .
