6.1.2 Connecting to a Σ-V or Σ-7 Servo Drive
This section describes how to connect to a Σ-V or Σ-7 Series Servo Drive.
Brake ON/OFF Circuit Example
A circuit is configured to turn the brake ON and OFF using the /BK contact output signal from
the SERVOPACK and a brake power supply. The following diagram shows a standard connec-
tion example.
*1. BK-RY: Brake control relay
*2. 90-V brake power source 200-V input voltage: LPSE-2H01-E
100-V input voltage: LPDE-1H01-E
A 24-VDC power supply must be supplied if a 24-V brake is used.
Note: Refer to the relevant SERVOPACK manual for connection details.
Parameter Settings
The SERVOPACK parameters that are related to controlling the holding brake are listed in the
following table.
