Page 44: Reset Method And Status Indications
There are two ways to configure the motor overtemperature indication. Example 1 The ACS880 primary control program has two separate temperature monitoring functions. In this example, one of these functions (External event function 1) is configured to monitor digital input DI6 (you can also use another digital input). When off (0), the function triggers the user-selected indication and shows the user-defined message. -
