317 Time out
(LIVE ZERO TIME O)
Settings:
1 - 99 sec.
10 sec.
Function:
If the value of the reference signal connected to the
input, terminal 1, falls below 50% of the setting in
parameter 336 for a period longer than the time set in
parameter 317, the function selected in parameter
318 will be activated.
Description of choice:
Set the desired time.
318 Function after time out
(LIVE ZERO FUNCT.)
Settings:
Off (OFF)
Stop and trip (STOP AND TRIP)
Function:
This parameter allows a choice of the function to be
activated if the value of the reference signal
connected to the input, terminal 1, falls below 50% of
the setting in parameter 336 for a period longer than
the time set in parameter 317.
If a time-out function (parameter 318) occurs at the
same time as a bus time-out function (parameter
514), the time-out function (parameter 318) will be
activated.
327 Pulse reference/feedback, max. frequency
(PULSE REF/FB MAX)
Settings:
100 - 70000 Hz
5000 H
Z
Function:
In this parameter, the signal value is set that
corresponds to the maximum reference/feedback
value set in parameter 205/415.
Description of choice:
Set the desired pulse frequency.
= factory setting. ( ) = parameter window text. [ ] = value for use in communication via serial communication port

This parameter allows a choice between the different
functions available for the input, terminal 1.
Scaling of the input signal is effected in parameters
338 and 339.
[0]
No operation. Is selected if the FC motor is not to
[5]
react to signals connected to the terminal.
Reference. Is selected to enable change of reference
by means of an analogue reference signal.
If other inputs are connected, these are added up,
taking account of their signs.
Feedback. Is selected if closed loop regulation with an
analogue signal is used.
