10.419 (ID 1015) Reference Step after Start of Auxiliary Drive 4
Location in the menu:
P2.9.15
(Pump and Fan Control Application)
Use this parameter to set a reference step that is added to the reference value when the auxiliary drive is started.

10.416 (ID 1012) Reference Step after Start of Auxiliary Drive 1
10.420 (ID 1016) Sleep Frequency
Location in the menu:
P2.1.15
(PID Control Application, Pump and Fan Control Application)
Use this parameter to set the limit below which the output frequency of the drive must stay for a set time before the drive goes to
the sleep state.
The drive goes to sleep mode (that is, the drive stops) when the output frequency of the drive is less than the frequency limit that is
set in this parameter for a time greater than that determined by parameter
ID 1017
. During the Stop state, the PID controller is
operating switching the AC drive to Run state when the actual value signal either falls below or exceeds (see parameter
ID 1019
) the
Wake-up level determined by parameter
ID 1018

10.421 (ID 1017) Sleep Delay
Location in the menu:
P2.1.16
(PID Control Application, Pump and Fan Control Application)
Use this parameter to set the minimum duration that the output frequency of the drive must stay below the set limit before the
drive goes to the sleep state.
See
10.422 (ID 1018) Wake Up Level
Location in the menu:
P2.1.17
(PID Control Application, Pump and Fan Control Application)
Use this parameter to set the level at which the drive wakes up from the sleep state.
The wake-up level defines the level below which the actual value must fall or which has to be exceeded before the Run state of the
AC drive is restored.
