CHAPTER 2 WIRING
2.2 P-N Junction
Directly connect the DC link circuit of two servo amplifiers to exchange power.
In a system having a powering (driving) shaft and regenerating (back tension) shaft such as the
2
winder/unwinder unit, the power consumption of the entire system can be reduced. Do not supply main
power to the servo amplifier on the other side of the P-N junction.
The capacity of the servo amplifier on the PN junction side must be equal to or less than that of the
servo amplifier on the power supply side.
