DSP LASER AP with MCS
10.4.2.8. Machine movement command (upstroke/downstroke/STOP)
Safety Output and Monitor
Le uscite di sicurezza sono preposte alla movimentazione della traversa mobile (asse Y)
della macchina.
Information :
We usually refer to hydraulic components because the great part of the
press brakes use them, but the safety outputs can command any type of
actuator, as long as the command is electric.
Depending on the hydraulic or electric configuration of the machine, it is possible to assign to
every output the state to assume in the different phases of the machine cycle (see Chap.
11.2).
Phases of the machine cycle managed by MCS:
•
High Speed
•
Low Speed
•
Stop
•
Upstroke
The state of the outputs can be assigned in the 4 states of the machine cycle, while it cannot
be assigned in the Lock state where no movement is allowed and the safety outputs are set
to 0V by MCS.
For every output (except OUTS8) we can activate the use of the relevant monitor. The
monitors of the first four outputs (OUTS1, OUTS2, OUTS3 and OUTS4) are managed by
MCS in relation to the machine cycle, so that it is suggested to use these outputs to drive the
High Speed Solenoid Valves (OUS1 and OUTS2) and the proportional solenoid valves
(OUTS3 and OUTS4). The management of the monitors of the remnant outputs (OUTS5,
OUTS6 and OUTS7) follows the state of these without being conditioned by the machine
cycle. These outputs can then be used to drive the other Solenoid Valves or other devices.
Information :
When the hemming function is active, by means of the programming
parameter B8, the output OUTS7 and the relevant Monitor (INS20)
cannot be used for any other function.
Information :
The status of the Monitor must be negated with respect to the state of the
relevant output. If OUTSn=+24V the relevant Monitor should be
MONITORn=0V. Vice versa, if OUTSn=0V, the relevant Monitor should
be MO24V.
