404 Terminal 27 stop (INPUT 27)
Value:
★
Motor coasting stop (MTR. COAST)

Quick-stop (Q-STOP)

Function:
Used for choosing between different possible
functions of terminal 27.
NB!:

NB!:
NB!:
The motor is only able to run if 24 V DC is
supplied from terminal 12 to terminal 27
(logic "1"). However, this feature can be dis-
regarded by using serial communication or
Local Mode.
Description of choice:
Motor coasting stop
[0]:
Chosen if the frequency converter is to "release" the
motor and the motor runs freely until stopping. When
the connection from terminal 12, 24 V DC, to terminal
27 is broken, motor coasting stop is effected.
Quick-stop
[1]:
Selected if the motor is to be stopped in accordance
with the alternative ramp time set in parameter 218.
When the connection from terminal 12, 24 V DC, to
terminal 27 is broken, this leads to a quick-stop.
DC braking
[2]:
Selected if the motor is to be stopped by energizing it
with a DC voltage for a certain time - as chosen in
parameters 306 and 308. This function is only active
when the value in parameters 306 and 308 are other
than 0. When the connection from terminal 12, 24 V
DC, to terminal 27 is broken, this leads to DC braking.
Reset and coasting stop
[3]:
Selected if coasting stop is to be activated (see under
coasting stop at the top of the description) and a
reset applied (see description of reset in parameters
400, 401) at the same time. When the connection
from terminal 12, 24 V DC, to terminal 27 is broken,
this leads to Reset and Coasting Stop.
Stop
[4]:
Chosen if it is desired to stop the frequency converter
(see description of stop in parameters 400, 401).
When the connection from terminal 12, 24 V DC, to
terminal 27 is broken, this leads to a Stop.

and parameter
402 Latch Start
[1]:
If a latch start has been selected in par. 402, latch
start with reversing will be set automatically.
NB!:
NB!:
NB!:
NB!:
NB!:
If 24 V DC is supplied from terminal 12 to
effect a start command (logic "1") to terminals
18 and 19 at the same time, the motor will
stop.
No operation
[2]:
As parameter 402.
External H-O-A Hand
[3]:
Selected if the H-O-A function is to be used externally
from the frequency converter to switch between
hand-operation (Hand) and the normal remote control
(Auto). By providing 24 V DC from terminal 12 to ter-
minal 16, the hand-operation mode is activated and
the output frequency can be adjusted by the refe-
rence selected as external hand-operation reference
in parameter 420.
Latch start Hand
[4]:
Selected for starting the inverter when the frequency
converter is in the hand-operation mode, "Hand".
When 24 V DC is supplied from 12 to terminal 19 for
min. 20 msec., the start will be activated.
