10.414 (ID 1010) Start Delay of Auxiliary Drives
Location in the menu:
P2.9.10
(Pump and Fan Control Application)
Use this parameter to set the delay time to start the auxiliary drive.
The frequency of the drive controlled by the AC drive must remain above the start frequency of the auxiliary drive for the time
defined with this parameter before the auxiliary drive is started. The delay defined applies to all auxiliary drives, which prevents
unnecessary starts caused by momentary start limit exceedings. See
.
10.415 (ID 1011) Stop Delay of Auxiliary Drives
Location in the menu:
P2.9.11
(Pump and Fan Control Application)
Use this parameter to set the delay time to stop the auxiliary drive.
The frequency of the drive controlled by the AC drive must remain below the stop limit of the auxiliary drive for the time defined
with this parameter before the drive is stopped. The delay defined applies to all auxiliary drives, which prevents unnecessary stops
caused by momentary falls below the stop limit. See
10.416 (ID 1012) Reference Step after Start of Auxiliary Drive 1
Location in the menu:
P2.9.12
(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.
The reference step is automatically added to the reference value always when the corresponding auxiliary drive is started. With the
reference steps, for example, the pressure loss in the piping caused by the increased flow can be compensated.
