It assigns the up and down
reference function for two of the
digital inputs.
DI5 = Up (NO contact)
DI6 = Down (NC contact)
Reference limits will be the
speed limits set in ‘G10 LIMITS’.
Programming a change ramp is
possible at:
G5.7 PMT ACL1=3%/s
G5.8 PMT DCL1=3%/s
G5.9 PMT ACL2=1%/s
G5.10 PMT DCL2=1%/s
G5.11 PMOT BRK=OFF
Note: In this mode, the reference
set by potentiometer will be
memorized even if the motor is
stopped and also in the case of a
power loss.
It operates in the same way as
option 4, but when the motor is
stopped or a power loss occurs,
the reference will not be
memorized. In this case the
minimum reference value set in
G10.1 or G10.3 will be the
default speed. This will happen
when the limit is above zero, if
the limit is equal or below zero,
the default speed will be zero.
Pumps program activation, in G1.7 PROG = PUMP, requires the following considerations:
There are some configuration options available when the pump program is active, which can be set in the same way
that the options available in the standard program.
Nevertheless, when the pump program is active, the drive will assume that only the configurable options from 50 to 75
(for G4.1.5 to G4.1.10) can be set, without taking into consideration the setting on parameter ‘G4.1.4 DIGIT I MODE’,
which means a block setting.
All that means that the user will configure the pump program freely, according to his requirements, selecting the correct
functionality and protections. For a correct programming of the digital inputs when the pump program is active, there is
additional information in ‘Pump Application Manual’, where information about Pump Control (G25) is included.
Note: Selection of the pump program will set all the Digital Inputs to mode ’00 – un used’. If re-programming is needed,
it will be necessary to configure their functionality in a separate way again. So it guarantees a safety installation
operation, avoiding that hardware external to the equipment can cause any kind of damage.
Note: The digital outputs will also be affected due to pump control activation.
To select one auxiliary pump it is necessary to act in the following way:
o Set any free digital input to options ’52 FIX PUMP1 FLT’, ’53 FIX PUMP2 FLT’, ’54 FIX PUMP3
FLT’, ’55 FIX PUMP4 FLT’ or ’56 FIX PUMP5 FLT’
o To enable the control of the pump in the corresponding screen G25.9.1, G25.9.2, G25.9.3, G25.9.4
and G25.9.5 respectively.
To remove this pump configuration and release the relay for another use, the user should:
o Disable the control of the pump in the corresponding screen G25.9.1, G25.9.2, G25.9.3, G25.9.4 or
G25.9.5 respectively.
