The following functions can be assigned to the freely configurable digital input:
Function Control via ”Fluxx” or via digital IOs Control via CAN bus Control via Profibus
Unused No function No function No function
Reference (reference
switch)
In the case of the reference type ”Edge” or ”Reference switch”, the digital input is evaluated as a reference
switch. When a reference run is effected and the reference switch is reached, the home position is set in
consideration of the settings carried out on the ”Reference” tab.
Output stage off The output stage of the inverter is switched off if this input
is activated, while the electronics/control is supplied further
on. If the motor is running at the time of activation, it will
coast in an uncontrolled manner after the output stage has
been switched off. There is no actively injected torque
available on the motor shaft.
After deactivation of the input, the drive can be restarted.
No function No function
Reference window No function No function No function
Start reference run The reference run which is specified in the ”Reference”
menu and which serves to the protective multiple earthing
of the drive or to define all absolute position values is
started when transition to the active status takes place, if
the drive has not yet been referenced beforehand. A second
referencing cannot be started via the input. For this
purpose, the digital input is to be selected as ”Reference
start” in the ”Reference” tab.
No function No function
Goto 99 If the input is activated, the current travel data set is interrupted immediately, and the travel data set 99 is
selected or started.
Synchronisation For synchronising several drive systems, the
”Synchronisation” function can be used. The term
”synchronisation” in this connection refers to the
simultaneous start of several drive systems. For this
purpose it is required to specify the number of the next
travel data set with a negative sign in the field ”Next travel
data set”. If, for instance, in the case of a linkage between
travel data sets, the travel set data number is entered in the
field ”Next travel data set” with a negative sign (e.g. -5 for
the fifth travel data set), the subsequent travel data set is
only started if the input is active.
No function No function
Stopover The current travel program is stopped if the input is active,
and the drive is decelerated to the speed 0. The output
stage remains active during stopover. As soon as the input
is deactivated, the program or the current travel data set is
continued.
No function No function
Single step mode In the case of a linkage of travel data sets, the subsequent
travel data set only is started if the input is active.
No function No function
Teach By means of the ”Teach” function, the current actual
position of the drive can automatically be transmitted as a
set position of the travel data set 0 under the following
conditions:
A The controller type of travel data set 0 is ”Absolute
position”
B The output stage has to be switched off (motor at zero
current)
This function can only be used in the operating modes
”Online level 1” or ”Offline” of the Fluxx program.
No function No function
Stopover at zero
current
The current travel program is stopped if the input is active,
and the drive is decelerated to the speed 0. Afterwards the
output stage is switched off (motor at zero current). As soon
as the input is deactivated, the output stage is activated,
and the program or the current travel data set is continued.
No function No function
