300 Terminal 16, input
(DIGITAL INPUT 16)
Function:
In this and the following parameters it is possible to
choose between the different possible functions rela-
ted to the inputs on terminals 16-33.
The function options are shown in the table on page
111. The maximum frequency for terminal 16, 17, 18
and 19 is 5 kHz. The maximum frequency for terminals
29, 32 and 33 is 65 kHz.
Description of choice:
No function is selected if the frequency converter is
not to react to signals transmitted to the terminal.
Reset zeroes the frequency converter after an alarm;
however, not all alarms can be reset.
Coasting stop inverse is used for making the frequency
converter let go of the motor to make it coast freely to
stop. Logic '0' leads to coasting stop and reset.
Reset and coasting stop inverse , is used for acti-
vating coasting stop at the same time as reset. Logic
`0' leads to coasting stop and reset
Quick-stop inverse is used for stopping the motor in
accordance with the quick-stop ramp (set in parameter
212). Logic '0' leads to a quick-stop.
DC braking inverse is used for stopping the motor by
energizing it with a DC voltage for a given time, see
parameters 125-127.
Please note that this function is only active if the value
of parameters 126-127 is different from 0. Logic '0'
leads to DC braking.
Stop inverse is activated by interrupting the voltage to
the terminal. This means that if the terminal has no
voltage, the motor cannot run. The stop will be effected
in accordance with the selected ramp (parameters
207/208/209/210).
None of the above-mentioned stop com-
mands (start-disable) are to be used as
disconnection switch in connection with
repairs. Cut mains instead.
NOTE
It must be noted that when the frequency
converter is at the torque limit and has re-
ceived a stop command, it will only stop if
terminal 42, 45, 01 or 04 has been con-
nected to terminal 27. The data choice on
terminal 42, 45, 01 or 04 must be
Torque
limit and stop [27].
Start, is selected if a start/stop (operating command,
group 2) command is desired. Logic '1' = start, logic '0'
= stop.
Latched start - if a pulse is applied for min. 3 ms, the
motor will start, provided no stop command (operating
command, group 2). The motor stops if Stop inverse is
activated briefly.
Reversing is used for changing the direction of rotation
of the motor shaft. Logic "0" will not lead to reversing.
Logic "1" will lead to reversing. The reversing signal
only changes the direction of rotation; it does not acti-
vate the start function.
Reversing requires that Both directions has been se-
lected in parameter 200.
Is not active if
Process control, closed loop
,
Torque
control open loop or Torque control, speed feedback
has been selected.
Start reversing , is used for start/stop (operating com-
mand, group 2) and for reversing with the same signal.
No signal is allowed on terminal 18 at the same time.
Acts as latch start reversing, provided latch start has
been chosen for terminal 18.
Is not active if
Process control, closed loop
has been
selected.
Start clockwise only, on is used if the motor shaft is
only to be able to rotate clockwise when starting.
Should not be used with
Process control, closed loop.
Start anti-clockwise only, is used if the motor shaft is
to rotate anti-clockwise when started.
Should not be used with
Process control, closed
loop .
