Example of I/O Signal Connections

The following diagram shows a typical connection example.
(1) SERVOPACK
 Σ-V Series
Control power supply
for sequence signal
Forward run prohibited
(Prohibited when OFF)
Reverse run prohibited
Deceleration limit switch
24 V
Safety function signal
∗1.
∗2. Connect when using an absolute encoder. When the encoder cable for the battery case is connected, do not connect a
backup battery.
∗3. The 24-VDC power supply is not included. Use a power supply with double insulation or reinforced insulation.
∗4. To turn the servomotor power ON, a safety unit must be connected and the wiring to activate the safety function must
be done. When not using the safety function, use the SERVOPACK with the safety jumper connector (provided as an
accessory) inserted into the CN8.
