Use an SELV-compliant power supply according to EN/IEC 60950-1 to input 24 VDC to the control power sup-
ply input terminals.
*2.
If using these terminals, contact your YASKAWA representative.
*3.
The SGD7S-210D, -260D, -280D, and -370D do not have the D1, D2, and D3 terminals.
*4.
Make sure you check the brake specifications of the Servomotor for the 24-VDC power supply input to the Ser-
vomotor brake power supply terminals.
*5.
SERVOPACKs without built-in Servomotor brake control do not have these terminals.
If you use a DC power supply input to the SERVOPACK, make sure to set parameter Pn001
to n.1 (DC power supply input supported) before inputting the power supply. Refer to
the following section for details.

None. (Do not connect anything to these terminals.)
These are the Σ-7S connection terminals for the Servomotor
Main Circuit Cable (power line).
Note: Do not connect the PE terminal to anything other than a ground
terminal.
In the following cases, remove the lead or short bar between
D2 and D3 and connect a Dynamic Brake Resistor between
D1 and D2.
• To specify the brake torque when stopping with the
dynamic brake
• To use a larger load moment of inertia than in the standard
specifications
The Dynamic Brake Resistor is not included. Obtain it sepa-
rately.

Connect these terminals to the Servomotor's holding brake
terminals. The holding brake terminals on the Servomotor do
not have any polarity.
This is the ground terminal to prevent electric shock. Always
connect this terminal.
