2.2.5 Automatic continuous stroke (operating mode 5)
Definition
This operating mode differs from the continuous mode in that two steps are
required to enable the machine for the first time:
• First, the automatic continuous stroke mode is enabled using the two-hand
control.
• Then the machine can be started by an external enable signal via the terminal.
Note
• If at the time of the two-hand activation there is an external enable signal, the
machine starts immediately.
• In this mode, the two-hand control acts as a command device only (not a
safety device). The operator must be protected by additional safety
equipment, e.g. ESPE!
