Fig. 31: Examples of Standard Connections between SERVOPACKs and Peripheral
Devices - SGD7S 200V - Rotary Servomotors
*1. This example is for a SERVOPACK with a three-phase, 200-VAC power supply input.
The pin layout of the main circuit connector depends on the voltage.
*2. External Regenerative Resistors are not provided by Yaskawa.
*3. The power supply for the holding brake is not provided by Yaskawa. Select a power
supply based on the holding brake specifications.
If you use a 24-V brake, install a separate power supply for the 24-VDC power supply
from other power supplies, such as the one for the I/O signals of the CN1 connector.
If the power supply is shared, the I/O signals may malfunction.
