Q&A
Q: What is the difference between the R4D and the R4C?
A: The R4D and R4C have the same dimensions (122×200mm) and identical digital input/output and analog interface configurations. The main difference is the expansion interface: the R4D is equipped with a CAN expansion interface, while the R4C has a reserved CAN&485 interface (the R4C's interfaces are in reserved status, while the R4D's CAN interface is a formal function).
Q: Which EtherCAT functions does the R4D support?
A: The R4D supports a 100Mbps bus rate and distributed clock (DC) functionality, with a minimum communication cycle of 200us. It can connect with INEXBOT controllers and master station devices that support the standard EtherCAT protocol.
Q: Which encoder types does the R4D interface support?
A: The R4D supports AB-phase incremental encoder input using a differential signal interface.
Q: Does the R4D support PWM output?
A: Yes. The R4D has a built-in PWM output interface, which can be used in applications such as speed control and dimming.
Q: What is the operating temperature range of the R4D?
A: The R4D operating temperature range is 0~60°C, with an even wider storage temperature range, making it suitable for industrial site deployment.
Q: Which devices can connect to the R4D's CAN expansion interface?
A: The R4D's CAN expansion interface can connect to devices supporting CANopen or custom CAN protocols, such as sensors, remote IO expansion modules, and drives.
