Description of Parameters
Figure 8-54: Example of Parameter Setting
Variable Speed Drive and One Auxiliary Drive
1010 Start delay of auxiliary
drives
7 (P1.9.10)
The frequency of the drive controlled by the frequency converter 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.
This prevents unnecessary starts caused by the start limit being momentarily
exceeded. See Figure 8-54.
1011 Stop delay of auxiliary
drives
7 (P1.9.11)
The frequency of the drive controlled by the frequency converter must remain below
the stop limit of the auxiliary drive for the time defined with this parameter before the
auxiliary drive is stopped. The delay defined applies to all auxiliary drives. This
prevents unnecessary stops caused by the stop limit frequency momentarily dropping
below the limit. See Figure 8-54.
