8.3 Isolating Transformer
z It is recommended that the power of drive unit is supplied by isolating transformer for
reducing the possibility of electric shock and jamming by power supply and electromagnetic
field.
z Drive units of 0.8kW and below can adopt single-phase power supply while drive units of
more than 0.8kW can adopt three-phase power supply.
We provide the following several models of transformers for the user to select. The user can
make a choice by referring to the power and actual load of servo motor.
