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 - Ref
MIN
An output signal is obtained, which is proportional
to the resulting reference value in the interval
Minimum reference, Ref
MIN
Ref (parameters 204/205).
MAX
Pulse feedback FB -FB
MIN
An output signal is obtained, which is proportional to the
feedback value in the interval Minimum feedback, FB
- Maximum feedback, FB
MAX
Output frequency 0-f .
MAX
An output signal is obtained, which is proportional to
the output frequency in the interval 0 - f
202 Output frequency, high limit, f
Pulse current 0 - I .
INV.
An output signal is obtained, which is proportional
to the output current in the interval 0 - I
Pulse power 0 - P .
M,N
An output signal is obtained, which is proportional to
the present output power. Par. 342 corresponds to the
value set in parameter 102 Motor power, P
Pulse temperature 0 - Temp.
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).

Description of choice:
Set the required frequency.
343 Precise stop function
(PRECISE STOP)
Value:
Precise ramp stop (NORMAL)
Counter stop with reset
(COUNT STOP RESET)
Counter stop without reset
(COUNT STOP NO RESET)
MIN
Speed-compensated stop (SPD CMP STOP)
Speed-compensated counter stop with reset
(SPD CMP CSTOP W. RES)
Speed-compensated counter stop without reset
(SPD CMP CSTOP NO RES)
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.
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
repetitive precision at the stopping point.
Counter stop. Once it has received a pulse start signal
the variable 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 will
activate the normal ramp down time (parameter 208).
The counter function is activated (starts timing)
at the flank of the start signal (when it changes
from stop to start).
Speed compensated stop. To stop at precisely
the same point, regardless of the present speed,
a stop signal received is delayed internally when
the present speed is lower than the maximum
speed (set in parameter 202).
