413 Terminal 60 Analog Input Current
(INPUT #60)
Value:
No operation (NO OPERATION)
[0]
★
0 to 20 mA (0 to 20 mA)
[1]
✔
4 to 20 mA (4 to 20 mA)
[2]
20 to 0 mA (20 to 0 mA)
[3]
20 to 4 mA (20 to 4 mA)
[4]
Function (parameters 412 and 413):
Choose the desired analog input references.
Description of choice (parameters 412 and 413):
Enter the type of analog input signals to inputs 53 and 60.
Choose voltage or current, and whether the signals are to
be normal or inverted. If two inputs are used for reference
signals, the total reference signal is the sum of those two
signals. If a PID controller is used without latched input be-
ing used ( terminal 17 parameter 401), one of the inputs
must be used for the feedback signal. If current control is
used as selected in parameter 102, one of these inputs
must be for setting the current limit.
NOTE:
If terminal 53 and/or terminal 60 is not used, NO
OPERATION [0] must be chosen in parameters 412
or 413 to avoid a reference fault.
NOTE:
If a 4 to 20 mA, 20 to 4 mA, 2 to 10 V, 10 to 2 V,
1 to 5 V, or 5 to 1 V reference signal is chosen and
no reference signal is connected, the drive will dis-
play a reference fault. These are also chosen in
Quick Set Up Menu steps 4 and 5.
414 Time Out Interval (TIME OUT)
Value:
0 to 99 seconds
★
100 = OFF
✔
005 sec
415 Time Out Interval Function (TIME OUT A)
Value:
★
Freeze (FREEZE)
[0]
Stop (STOP)
[1]
Jogging (JOG)
[2]
Max. speed (MAX)
[3]
Function: (parameters 414 and 415):
If one of the “live zero” signals, such a 4 to 20 mA, has
been selected and the actual signal is less than 50% of this
minimum value, REF FAULT will be displayed immediately.
The desired operating mode selected in parameter 415 will
be followed after the programmed time delay set in param-
eter 414 has expired.
Description of choice: (parameters 414 and 415):
The desired operating mode is selected in parameter 415.
Freeze [0] makes the drive go to the speed which is asso-
ciated with the minimum speed reference signal.
Stop [1] stops the drive by setting its output frequency to 0
Hz.
Jog [2] sets the drive to the speed set in parameter 203.
Max [3] sets the drive to its maximum frequency.
This function is not active during “Local/Hand” operation or
when closed loop control has been selected in parameter
101.
420 Reference Type to H-O-A (EXT.HOA RE)
Value:
★
Voltage #53
[0]
Current #60
[1]
Speed up/down (SPEED UP/DOWN)
[2]
Function:
When external H-O-A is selected in parameter 003, a refer-
ence for manual operation (Hand) must be selected. This
reference cannot be the same one that is used for remote
control (Auto).
Description of choice:
If
Voltage #53 [0] is selected, an analog voltage reference
at terminal #53 is used, which is programmed in parameter
412.
If
Current 60 [1] is selected, an analog current reference at
terminal #60 is used, which is programmed in parameter
413.
If
Speed Up/Down [2] is selected, digital speed up/down
(floating point control) is used, which is programmed in pa-
rameter 406.
