250 Parameters
75.25 Drive start dly Start delay for the pump that is directly controlled by the
drive. This does not affect the starting of the auxiliary pumps.
WARNING! There must always be a delay set if the
pumps are equipped with star-delta starters. The
delay must be set longer than the time setting of the
starter. After the pump is switched on by the relay output of
the drive, there must be enough time for the star-delta starter
to first switch to star and then back to delta before the pump
is connected to the drive.
0…600 s Start delay for drive-controlled pump. 1 = 1 s
75.26 Master speed acc Defines the acceleration time in case the latest reference
received by the drive is higher than the previous reference.
This is likely to happen when the master status is passed on
from one drive to another. The parameter sets the ramp-up
time as seconds from zero to maximum frequency (not from
previous reference to new reference).
The parameter is effective only in the Copy of mstr and
Master speed follower modes. See parameter 75.03
Follower mode.
0…1800 s Acceleration time. 1 = 1 s
75.27 Master speed dec Defines the acceleration time in case the latest reference
received by the drive is lower than the previous reference.
This is likely to happen when the master status is passed on
from one drive to another. The parameter sets the ramp-
down time as seconds from maximum frequency to zero (not
from previous reference to new reference).
The parameter is effective only in the Copy of mstr and
Master speed follower modes. See parameter 75.03
Follower mode.
0…1800 s Deceleration time. 1 = 1 s

76 MF communication
Communication configuration for applications consisting of
multiple pumps with dedicated drives.
76.01 Enable MF comm Enables/disables drive-to-drive communication through the
D2D link.
Note: Drive-to-drive communication can only be enabled if
the embedded fieldbus interface is disabled (parameter
58.01 Protocol ena sel is set to Disabled).
No Drive-to-drive communication disabled. 0
Yes Drive-to-drive communication enabled. 1
76.02 Pump node Node number of the drive on the drive-to-drive link.
Notes:
• Each drive on the link must have a unique node number.
• If the drive is not given a priority class, the node number is
also used in determining the starting order of pumps.
0…8 Node number. 1 = 1
76.03 Master enable Determines (or defines a source that determines) if the drive
is allowed to be master on the drive-to-drive link.
No The drive can only be a follower on the drive-to-drive link. 0
Yes The drive is allowed to be master on the drive-to-drive link. 1
Const Bit pointer setting (see Terms and abbreviations on page
109).
