[2] Installation
Powering on the weaving machine after wiring between the machine and the inverter box will turn on the ZERO
POSITION ALARM LED (PL2) located in the inverter box, as well as displaying alarm 23 or 32 on the servo amplifier
7-segment display. This is because the cable between the servomotor and servo amplifier was disconnected at the time of
shipment. Therefore, you need to register the zero point according to the procedure below.
