1 Overview
During the communication and data exchange between the PLC and V90PN, it is often necessary to read the actual operating data of the driver for display or calculation. This article introduces two methods for reading the driver's relevant operating data.
2. Reading runtime data
Method 1: When V90PN is configured in EPOS control mode and standard message 111 is selected, the message contains a user-defined reserved word (PZD12) in both the receiving and sending directions, as shown in Figure 2-1.
Figure 2-1 User-defined reserved words
At this point, the content of the transmission direction PZD12 can be defined by modifying parameter P29151 (user-defined PZD transmit word). Selectable operating data includes actual torque, actual absolute current, and DI status. For other operating data, please refer to Method 2.
Method 2: The driver's operating data can be read using the FB286 (SINA_PARA) or FB287 (SINA_PARA_S) function blocks based on aperiodic communication.
