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 fulfilled.
Terminal can also be used for frequency output.
Parameter 342 sets the maximum pulse frequency.
Description of choice:
Pulse reference Ref
MIN
- Ref
MAX
An output signal is obtained, which is proportional to
the resulting reference value in the interval Minimum
reference, Ref

(pa-
rameters 204/205).
Pulse feedback FB

.
An output signal is obtained, which is proportional to
the feedback value in the interval Minimum feedback,

An output signal is obtained, which is proportional to
the present output power. Par. 342 corresponds to the
value set in parameter 102

Pulse temperature 0 - Temp.
MAX
.
An output signal is obtained, which is proportional to
the present heatsink temperature. 0 Hz corresponds
to a heatsink temperature of less than 68 °F (20° C),
and 20 mA corresponds to 212 °F (100° C).
NOTE
Output terminal 46 is not available on De-
viceNet. Minimum output frequency at fre-
quency output = 16 Hz

Function:
This parameter is used for setting the pulse output sig-
nal's maximum frequency.
Description of choice:
Set the required frequency.

Precise stop function
(Precise stop)
Value:
Precise ramp stop (normal)

Counter stop with reset
(Count stop 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 re-
set
(Spd cmp cstop no res)
[5]
Function:
In this parameter you select which stop function is per-
formed in response to a stop command. All six data
selections contain a precise stop routine, thus ensur-
ing a high level of repeat accuracy.
The selections are a combination of the functions de-
scribed below.
NOTE
Pulse start [8] may not be used together
with the precise stop function.
Description of choice:
Precise ramp stop
[0] is selected to achieve high re-
petitive precision at the stopping point.
Counter stop
. Once it has received a pulse start signal
the adjustable frequency drive runs until the number of
pulses programmed by the user have been received
at input terminal 33. In this way an internal stop signal
