38 Quick start-up guide
ESP application minimum configuration
This section contains the following alternative control schemes for starting up the
drive with the ESP control program.
Note: For other ESP control program features, refer to the corresponding chapter of
this manual.
ESP control
In case Fieldbus is used as the primary
control interface for the application, the ESP
control word provides suitable access to all
major functions of the ESP control program. 74.01 ESP control word
Configure restart delay function.
The function prevent undesired pump start
while fluid column is draining through the
pump.
Note: For further information on Backspin
supervision function, see Backspin
supervision (page 42 ).
74.20 Restart delay enable
74.21 Restart delay time
ESP reference control
Select the source for the production speed
reference. 75.11 Pump speed ref source
Set the frequency reference if parameter
75.11 Pump speed ref source is selected as
Fixed speed ref .
75.12 Fixed speed ref
Set the frequency reference scaler.
Note: The used speed reference = 75.19
Maximum production speed * ( 75.11 Pump
speed ref source / 75.13 Speed reference
scaler .
If 75.13 Speed reference scaler = 0, then
there is no scaling: The used speed
reference =
75.11 Pump speed ref source .
75.13 Speed reference scaler
Set starting speed at which drive will start
modulating. 75.15 Starting speed
Set the desired acceleration time for ESP
motor to speed up from zero to the value set
in parameter
46.02 Frequency scaling .
75.21 Acceleration time
Set the desired deceleration time for ESP
motor to slow down from the value set in
parameter
46.02 Frequency scaling .
75.22 Deceleration time
