DSP LASER
DSPLSR01EN 49
INPUTS USED BY EVERY FUNCTION
Each function needs specific inputs to be executed. If an input is not used by any function, it
can be left disconnected.
The list of the inputs used by every function of DSP LASER is reported here below: verify,
depending on the chosen option, which inputs are used and which can be left disconnected.
Blanking Type A: uses the inputs 'Press brake closing pedal (IN PD)' and 'Press brake
opening (IN AP)'.
Blanking Type B: uses the inputs 'High speed in press brake closing (IN AV)' and 'Press
brake opening (IN AP)'.
Stopping Distance Check: uses the inputs 'High speed in press brake closing (IN AV)',
'Stopping Distance Check (IN VSA)' and 'Maximum Top Dead Centre (IN PMSM)'.
Restart Interlock: uses the inputs 'High speed in press brake closing (IN PD)' and 'High
speed in press brake closing (IN AV)'.
For example in the configuration RXA211, where the functions Blanking type A, Stopping
Distance Check and Restart Interlock, all the inputs shall be connected. In the configuration
RXB200, instead, only the inputs 'High speed in press brake closing (IN AV)' and 'Press
brake opening (IN AP)' shall be connected, because used by the Blanking Type B, while the
signals 'High speed in press brake closing (IN PD)', 'Stopping Distance Check (IN VSA)'
and 'Maximum Top Dead Centre (IN PMSM)' can be left disconnected because not used by
any function of this configuration.
Note: the power supply signals, the synchronism signal (IN SINC) and the signals Operating
mode 1, Operating mode 2 and Operating mode 3 must be always connected,
independently from the chosen configuration.
Safety PLC
If only one safety PLC is used and You wish to interface the PLC outputs, which command
Press brake opening (IN AP) and High speed in press brake closing (IN AV) directly with
DSP LASER, it is necessary to act as follows:
- Verify that the voltage of the outputs is, at most, 24V DC;
- Connect 0Vcc, which the outputs of safety PLC refers to, to the clamp 0Vcc of AL module
if present, or to 0Vdc of the RX module.
Connection of DSP LASER AP inputs to inductive signals
If the RX input signals are taken at the ends of the inductive components, these have to be
equipped with VDR or diode or proper components for the suppression of the voltage
peaks.
