Adjustment 25 MIN FLUX
(Default) (=100%)
Setting 100
Notes If MIN FLUX is set below 100% and the reference
input equals the feedback input, then the motor
voltage will be reduced to improve motor
efficiency. However, this can cause surging
of the motor voltage if the reference or feedback
signals are varying. To avoid surging, increase
MIN FLUX to 100%.
Adjustment 42 DEC3
(Default) (=10.0Hz/s)
Setting 2.0
Notes Slower to limit current required to decelerate
pump and to prevent regeneration (VLT).
Adjustment 54 FB RLY
(Default) (= 10.0Hz)
Setting 5.0
Notes Hysteresis band around the reference
frequency outside which the feedback sense
relay changes state.
MODES
Mode 64 REF FR
(Default) (= 010V)
Setting 010V
Notes 010V is the reference input.
Mode 65 FB SRC
(Default) (= 0/LOOP)
Setting 420mA
Notes Connects the 420mA input as the feedback
source.
Mode 66 I/P MODE
(Default) (= 01)
Setting 022 WIRE
Notes Sets the multi-function inputs up for two wire
control.
Mode 68 O/P RELAY 2
(Default) (= 00 NO FAULT)
Setting 13 FEEDBACK SENSE
Notes Sets relay 2 to open when the feedback signal
is higher than the reference plus half the
hysteresis.
Mode 71 REV INHIBIT
(Default) (= N)
Setting Y
Notes Inhibits operation in the reverse direction should
this ever inadvertently be demanded.
Mode 78 RUN AT MINIMUM FREQUENCY
(Default) (= N)
Setting Y
Notes Allows the drive to run at the minimum frequency
(Screen 21) causing the pressure rise
necessary to reach the upper hysteresis level.
