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
74.1 ESP control wordIf Fieldbus is used as the primary control
interface for the application, the ESP con-
trol word provides suitable access to all
major functions of the ESP control pro-
gram.
74.20 Restart delay enableConfigure the restart delay function.
74.21 Restart delay timeThe function prevents undesired pump
start while fluid column is draining through
the pump.
Note: For further information on Backspin
supervision function, see Backspin supervi-
sion (page 46).
ESP reference control
75.11 Pump speed ref sourceSelect the source for the production speed
reference.
75.12 Fixed speed refSet the frequency reference if parameter
75.11 Pump speed ref source is selected as
Fixed speed ref.
75.13 Speed reference scalerSet 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 refer-
ence = 75.11 Pump speed ref source.
75.15 Starting speedSet starting speed at which drive starts
modulating.
75.21 Acceleration timeSet the desired acceleration time for ESP
motor to speed up from zero to the value
set in parameter 46.2 Frequency scaling.
75.22 Deceleration timeSet the desired deceleration time for ESP
motor to slow down from the value set in
parameter 46.2 Frequency scaling.
