Servo system setting
 Framework
The controller outputs the pulse signals to the chain conveyor. When the chain conveyor
delivers the packing contents, it uses the pulse by-pass function built in the servo drive to
transmit the pulses to other slave axes at the same time, so the master axis can send pulses to
other slave axes with the slave servos. The delay time for each axis is 50 ns and the pulse
signal does not attenuate during transmission.
To use the E-Cam phase alignment function, install the mark sensor on the wrap feeder and use
DI: [0x35]ALGN to correct the E-Cam phase. The mark sensor for the synchronous Capture axis
is installed on the chain conveyor and sends the signals through the high-speed input point
(DI7) to the servo drives controlling the wrap feeder and cutter. In other words, the synchronous
Capture axis provides the source pulses for E-Cam master axis of these two servo drives.
The electrical framework is as shown in Figure 7.3.11.2.
