Connecting to Peripheral Devices
This section shows a standard example of connecting Σ-Series products to peripheral devicesand briefly explains how to connect to each peripheral device.
NOTE Read the following notes before wiring:
• Connect only one cable to one terminal. Never connect two cables to one terminal.
• Do not solder the cable.
• Peel back the cable shield by about 10mm (0.39in.) min. Then insert the cable into the terminal securely and tighten the screw. Never leave the bare wires outside of the termianl.
• When the cable is inserted into the flat terminal, use the following ferrules. Non−insulated ferrules, 2.5mm2 or less (Made by PHOENIX CONTACT)
<Reference> Terminal block type: FRONT 2.5H/SA5
Form a power ON sequence as follows:
a) Form a power ON sequence so that the main power is turned OFF when a servo alarm signal is output. (See the circuit diagram shown on the previous page.)
b) Hold down the power ON push-button for at least two seconds. The Servopack outputs
a servo alarm signal for approximately two seconds or less when the power is turned ON. This operation is required to initialize the Servopack.
After turning the power OFF, do not touch the power terminals for 5 minutes. High voltage may remain in the Servopack.
Avoid frequently turning the power ON and OFF. Since the Servopack has a capacitor in the power supply, a high charging current flows (for 0.2 second) when the power is turned ON. Therefore, frequently turning the power ON and OFF causes the main power devices (such as capacitors and fuses) to deteriorate, resulting in unexpected problems.
