SieiDrive ADV200 and XVy-EV are two drives families designed to control synchronous or asynchronous motors.
The SieiDrive ADV200 inverter can be used with asynchronous motors controlling the Extruders and pump in the Hydraulic machines.
     • power range from 0.75kW up to 1.5MW
     • Field Oriented Control in Sensorless mode

Servo drive type SieiDrive XVy-EV, for brushless motors, is used for clamp, translations, Parison and nozzle in the Full Electric machines.
     • power range from 1.5kW up to 315kW
     • Feedback from Resolver, Encoder SinCos and Absolute Encoder EnDat, SSI and Hyperface

Main features:
     • communication via GDNet and CANopen
     • integrated PLC under standard IEC 61131-3 (5 programming languages)
     • configuration tool integrating a software oscilloscope with synchronous sampling (buffered) at 250µsec us for an easy commissioning
