When you use an option and peripheral equipment (200 V class)
■When you use a regenerative option for 5 kW or less servo amplifiers
• The lead wire between P+ terminal and D terminal should not be connected.
• The regenerative option wire should be connected between P+ and C terminal.
• Twisted wires should be used. Page 341 Connection of regenerative option
■When you use a regenerative option for 7 kW or more servo amplifiers
• 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.
• The regenerative option wire should be connected between P+ and C terminal.
• Twisted wires should be used. Page 341 Connection of regenerative option
■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. Page 353
