Function
Inputs Description
RESET 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 RESET input. This will have
the following effects:
Ĉ the NC record pointer is reset to 0
Ĉ 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
Ĉ the ACK outputs will be reset
Ĉ the set starting programs are made available
Ĉ any faults are acknowledged.
ENABLE Controller enable
An 0−signal at this input causes:
Ĉ the controllers of all axes will be switched off. The valve control voltage will be set
to an electrical medium value (offset).
Ĉ the READY output will be reset
Ĉ 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:
Ĉ the READY output will be set again
Ĉ the valve control voltages and the controllers of all axes will be switched on
Ĉ the current position will become the nominal position (closed−loop controlled
stop)
Ĉ If you are using a stepping motor, reference travel must be carried out again.
With the next CLK signal, the positioning task at the RECBIT... inputs will be
processed.
In the following cases a rising signal edge is required at the ENABLE input for conĆ
troller enable.
Ĉ during the first commissioning after the project−specific parameters have been set
Ĉ after a Data Reset and resetting of the project−specific parameters
Ĉ when the movement test has been carried out.
