FCD Series
Description of choice:
Set the required pulse reference or pulse feedback
to be connected to terminal 33.
328
328 Pulse Max. 29
(PULSE MAX 29)
Value:
1000 - 67600 Hz
✭
5000 Hz
Function:
This parameter is used for setting the signal value
that corresponds to the maximum value set in pa-
rameter 205
Maximum reference, Ref
MAX
or to the
maximum feedback value set in parameter 415
Max-
imum feedback, FB
MAX
.
Description of choice:
Set the required pulse reference or pulse feedback
to be connected to terminal 29.
341
341 Digital output terminal 46
(DO 46 FUNCTION)
Value:
✭
Drive ready (UNIT READ Y)
[1]
✭
See the selection made in parameter 323
Relay
output
.
Function:
The digital output can be used for giving the present
status or warning. The digital output (terminal 46)
gives a 24 V DC signal when a given condition is ful-
filled.
Description of choice:
Pulse output
is to be selected if a pulse sequence is
required that corresponds to the reference value.
Pulse output
can only be selected in parameter 341
Digital output
.
Pulse Output
cannot be selected if
Pulse Reference
or
Pulse Feedback
is selected in
parameter 305.
See parameter 323
Relay output
for the other de-
scriptions.
342
342 Terminal 46, max. pulse scaling
(DO 46 MAX. PULS)
Value:
150 - 10000 Hz
✭
5000 Hz
Function:
This parameter is used for setting the pulse output
signal’s maximum frequency.
Description of choice:
Set the required frequency.
343
343 Precise stop function
(PRECISE STOP)
Value:
✭
Normal ramp stop (NORMAL)
[0]
Counter stop with reset
(COUNT STOP NO RESET)
[1]
Counter stop without reset
(COUNT STOP NO RESET)
[2]
Speed-compensated stop (SPD CMP STOP)
[3]
Speed-compensated counter stop with reset
(SPD CMP CSTOP W. RES)
[4]
Speed-compensated counter stop without reset
(SPD CMP CSTOP NO RES)
[5]
Function:
In this parameter you select which stop function is
performed in response to a stop command. All six
data selections contain a precise stop routine, thus
ensuring a high level of repeat accuracy.
The selections are a combination of the functions
described below.
NB!:
Pulse start [8] may not be
used together with the precise stop function.
Description of choice:
Normal ramp stop
[0] is selected to achieve high
repetitive precision at the stopping point.
Counter stop
. Once it has received a pulse start sig-
nal the frequency converter runs until the number of
pulses programmed by the user have been received
at input terminal 33. In this way an internal stop
signal will activate the normal ramp down time (pa-
rameter 208).
