When you use a brake unit and power regeneration converter for 5 kW or more servo
amplifiers
• For 5 kW servo amplifiers, the lead wire between P+ terminal and D terminal should not be connected.
• For 7 kW servo amplifiers, the lead wire of the built-in regenerative resistor connected to P+ terminal and C terminal should
not be connected.
• Wires of a brake unit or power regeneration converter should be connected to P+ terminal and N- terminal.

• Twisted wires should be used when wiring is over 5 m and equal to or less than 10 m using a brake unit.
■
When you use a power regeneration common converter
• For 5 kW or less servo amplifiers, the lead wire between P+ terminal and D terminal should not be connected.
• For 7 kW servo amplifiers, the lead wire of built-in regenerative resistor connected to P+ terminal and C terminal should not
be connected.
• The wire of power regeneration common converter should be connected to P4 terminal and N- terminal.
