8.2 POWERING AND EMERGENCY STOP
8.2.1 Powering up
The main power is supplied by the interface cable. Before connecting the interface cable to the
lathe, make sure the power supply meets the interface specifications.
Depending on the power supplied by the lathe a Transformer (optional) may be needed.
The power supplied to the bar feeder should be protected by a circuit-breaker (6A max) located
in the lathe.
The servo motor of bar feeder is equipped with a built-in absolute encoder that continuously
controls the position of the carrier. When the bar feeder is powered down or there is a power
failure, this position is kept in the memory by the PLC.
When powering up, the pusher position value saved is immediately taken into account. The PLC
reads signals from sensors and gives the operator allowable operations only.
