Function Description
START/
RESET
Start/continue programs or quit faults
The sequence of created programs will be started or continued or a fault will be
acknowledged with a rising edge at this input. Prerequisites:
 there must be a 1−signal at the STOP input
 there must be a 1−signal at the ENABLE input
in order to start/continue: there must
be a 1−signal at the READY output.
Reset program
If there is a 0 signal at the STOP input and a 1 signal at the ENABLE input, a RESET
(Program Reset) can be triggered by a rising edge at the START input. This will have
the following effects:
 the NC record pointer is
reset to 0
 the pre−settings G90 and G02 (speed and acceleration values and workpiece mass
in initial state), as well as the positioning quality class set in the application data
become valid
 the nominal value input is switched off (M12)
 all settings undertaken with M10, M11, M13 or M14 are reset to the
defined stan
dard values (parameter set for the axis, Nominal value specification" tab)
 pre−switch off values defined with G25 are reset again
 direct control of the valve voltage (M39) is deactivated
 all settings undertaken with M40 and M41 are reset to the standard values
 all freely programmable outputs and the SYNC outputs are
reset
 the set starting programs are made available
 any active faults are acknowledged.
All flags (F), registers (R) and position registers (@) remain unchanged.
ENABLE Controller enable
An 0−signal at this input causes:
 the controllers of all axes will be switched off. The valve control voltage will be set
to an electrical medium value (offset).
 the READY output will be reset
if you use a stepping motor, the ENABLE signal for the stepping motor controller
will be reset and
the reference position will be deleted.
No further positioning tasks will then be accepted.
If there is a 1−signal again at this input:
 the READY output will be set
 the valve control voltages and the controllers of all axes will be switched on
 the current position will become the nominal position (closed−loop controlled
stop).
If you are using a stepping motor, reference travel must be carried out again.
At the next ST ART signal, the program sequence will be continued.
In the following cases a rising signal edge is required at the ENABLE input for
controller enable.
 during the first commissioning after the project−specific parameters have been
set
 after a Data Reset and resetting of the project−specific parameters
 when the movement test has been carried out.
