QUICK LOAD SERVO 80 S2
2.2.4. Servo amplifier
The SERVO amplifier enables the programmable controller to control 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, and, therefore, the axes do not need to be placed at zero when the bar feeder
is powered on.
Although the batteries last for a relatively long time (2-3 years), it is advisable to keep spares on hand.
When a battery becomes low, the amplifier signals this through a control light. The battery is not
rechargeable, and must be replaced right away. The replacement must be done while the bar feed system
is still powered up. The reference for the battery is 44.0107.
Procedure:
1. Disconnect the connector CN4 (A).
2. Open the battery compartment (B) according to the procedure below.
The wires on the extremities of the battery connecting it to the connector are part of the battery.
3. Fit the new battery inside the support and close it.
Connect the connector.
Used batteries must be disposed of in an ecologically safe manner.
