AN1AN2 function
XXXXXXXX
Inde-
pend-
ent
Operating logic of the analogue inputs AN1,AN2:
• Independent. The active sensor is relative to analog input 1 while the sensor connected
to analog input 2 acts as an auxiliary in case of failure of the sensor or analog input 1.
• Selectable. The active sensor may be selected via digital input 3.
• Difference 1-2. The digital difference in absolute value is performed between the meas-
urements of the analog input 1 and the analog input 2.
• Higher value. The maximum value between the measurements of the two sensors is
considered.
• Lower value. The minimum value between the measurements of the two sensors is con-
sidered.
Digital input1
N.O./N.C.
N.O.
If N.O.(Normally Open) is selected, the device will continue to operate the motor if digital
input 1 is open. Conversely, it will stop the motor if digital input 1 is closed.
Selecting N.C. (Normally Closed) will continue to operate the motor if digital input 1 is
closed. Conversely, it will stop the motor if digital input 1 is open.
Digital input2
N.O./N.C.
N.O.
If N.O. (Normally Open) is selected, the device will continue to drive the motor if digital in-
put 2 is open. Conversely, it will stop the motor if digital input 2 is closed.
Selecting N.C. (Normally Closed) will continue to drive the motor if digital input 2 is closed.
Conversely, it will stop the motor if digital input 2 is open.
Digital input 2 is also used to select set value 1 or set value 2 in the control mode
Const.value 2set or to select working frequency 1 or 2 in the control mode Fix speed 2
val..
Digital input3
N.O./N.C.
N.O.
If N.O. (Normally Open) is selected, the device will continue to drive the motor if digital in-
put 3 is open. Conversely, it will stop the motor if digital input 3 is closed.
Selecting N.C. (Normally Closed) will continue to operate the motor if digital input 3 is
closed. Conversely, it will stop the motor if digital input 3 is open.
Digital input 3 is also used to select sensor 1 or sensor 2 when the parameter AN1AN2
function is set to Selectable.
Digital input4
N.O./N.C.
N.O.
If N.O. (Normally Open) is selected, the device will continue to drive the motor if digital in-
put 4 is open. Conversely, it will stop the motor if digital input 4 is closed.
Selecting N.C.(Normally Closed) will continue to operate the motor if digital input 4 is
closed. Conversely, it will stop the motor if digital input 4 is open.
Digital input 4 is also used to select the main or auxiliary control mode in case they are
different.
Digital input 4 also acts as an alarm reset.
Man reset In Dig1
OFF
Enabling or disabling of the manual reset of the digital input.
Man reset In Dig2
OFF
Enabling or disabling of the manual reset of the digital input.
Dig.In.2/3 delay
t = XX [s]
1
Delay of digital inputs 2 and 3.
Digital inputs 1 and 4 have a fixed delay of 1 second.
