(8) Servo amplifier
By means of the SERVO amplifier, the programmable controller controls the movements of the motor.
The input values, as well as the position of the pusher carrier, are continuously registered. The values are
saved by means of a battery. Therefore, the axles do not need to be placed at zero when the bar feeder
is powered up.
Ensure that the emergency stop equipment or device is connected and working
correctly before operating the motor that is connected to a mechanical system.
