NOTES:.
1. If a fault occurs that has a Y in the “Controlled Stop” column, and P21 (Controlled Fault Stop) is set to
On, and P9 (Stop Mode) is set to dcL, then the starter will perform a voltage decel to stop. Otherwise it
will coast to stop.
2. If a fault occurs that has a Y in the “Auto Reset” column, and P22 (Auto Fault Reset Time) is set to some
value other than OFF, then the fault will automatically be cleared after the time specified by P22.
3. Manual reset is accomplished by pressing the reset button on the LED display. See Figure 38. A stack
over temperature fault (number 61) requires pressing the reset button located on the stack first.
