Function:
The different possible functions related to the inputs
on terminals 16-33 listed in the table above, are only
accessable when running in FC profile..
The maximum frequency for terminal 16, 17, 18,
19, 27, 32, 33 and 37 is 5 kHz. The maximum
frequency for terminal 29 is 50 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.
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.
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).
None of the above-mentioned stop
commands (start-disable) are to be used
as disconnection switch in connection
with repairs. Cut mains instead.
Start , is selected if a start/stop (operating
command, group 2) command is desired. Logic
’ 1 ’ = start, logic ’ 0 ’ = stop.
Reversing is used for changing the direction of rotation
of the motor shaft. Logic ’ 1 ’ will lead to reversing.
The reversing signal only changes the direction of
rotation; it does not activate the start function.
Jog is used for overriding the output frequency to
the jog frequency set in parameter 213. The ramp
time can be set in parameter 211. Jog is not active
if a stop command has been given (start-disable).
Jog does not override a start signal.
NB!:
The Jog function is not available in Crane profile.
If the VLT 5000 Crane is programmed to run
as a normal VLT 5000 (see parameter 512),
the Jog function will, however, be available.
