Frequently Asked Questions
Q: Can I use the 1766-L32BXB/B to drive a servo motor for positioning control?
A: Yes. The B version controller of this model provides three 100kHz high-speed outputs, which can be configured as Pulse Train Output (PTO). This allows it to send pulse and direction signals to servo drives (such as the Panasonic A5 series), thereby achieving speed and position control of the servo motor. You need to configure it using PTO-related instructions in programming software (such as RSLogix 500).
Q: Why does the relay output I use to control indicator lights fail so quickly?
A: Although relay outputs have a large current carrying capacity, their electrical life is limited, especially in applications with frequent switching (such as rapidly flashing indicator lights). The mechanical life of a relay can typically reach 20 million cycles, but under load switching conditions, the electrical life is significantly shortened depending on the load type and current magnitude. For indicator lights requiring high-frequency switching (e.g., twice per second), it is recommended to use the FET (transistor) type solid-state output on this controller, as its contactless and long-life characteristics are more suitable for such applications.
Q: What are the functional differences between the 1766-L32BXB/B and the earlier A version?
A: The most significant difference lies in the support for the Modbus TCP protocol. While the A version controller also has an Ethernet port, it does not support the Modbus TCP protocol and can only support Modbus RTU via the serial port. The B version, however, fully supports Modbus TCP/IP on the Ethernet port, which is crucial for applications requiring Modbus communication with third-party devices (such as power meters, frequency converters, etc.) via Ethernet.
