(c) When you use an option and auxiliary equipment
1) 200 V class
a) 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.
A twisted cable should be used. (Refer to section 11.2.4.)
b) 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.
A twisted cable should be used. (Refer to section 11.2.4.)
c) When you use a brake unit and power regeneration converter for 5 kW or more servo
amplifiers
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 the built-in regenerative resistor connected to P+
terminal and C terminal should not be connected.
Brake unit, power regeneration converter should be connected to P+ terminal and N-
terminal. (Refer to section 11.3 to 11.4.)
A twisted cable should be used when wiring is over 5 m and under 10 m using a brake unit.
(Refer to section 11.3)
d) 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. (Refer to section 11.5.)
e) The power factor improving DC reactor should be connected between P3 and P4. (Refer to
section 11.11.)
