Some alarm condition cause the motor to trip or stop operation. For example, if an over temperature condition exists, the device will shutdown to protect the motor and all other components from damage.
Diagnostic information is also available on the display. The operator can access the diagnostic information from a menu option while in Remote Control mode. Press the menu key is access the diagnostic menu and review all the diagnostic information. The operator can view speed feedback, speed loop feedback, and the scaled motor output voltage.
Some alarms display as hexadecimal codes. For example, 0X0020 indicates the device is running at an over voltage condition.
