  • Page 6: Introduction

    8 optically isolated digital outputs. The SI-I/O 24 Plus module has been designed to work alongside the PTi210 Motion Made Easy option module to provide the same digital I/O and main motor encoder input as the Epsilon EP servo drives. A 44-way high density D-type connector is used to provide both the encoder input and digital I/O connections.

  • Page 7: Installing The Option Module

    The SI option mounting kit can be ordered from the supplier of the drive. Refer to the Digitax HD M75X Series Installation and Technical Guide for further information. NOTE Once fitted, the option module remains at an angle with respect to the drive. SI-I/O 24 Plus User Guide...
