System Design
*1. The left value is for single-phase input power, and the right value is for three-phase input power.
*2. Use the same wire sizes for B1 and B2.
* 3. Connect an OMRON Servomotor Power Cable to the Servomotor connection terminals.
 Wire Sizes and Allowable Current (Reference)
The following table shows the allowable current when there are three power supply wires.
Use a current below these specified values.
