WARNING & FAULT MESSAGES
99
SCREEN DESCRIPTION
No Motor. The drive has not detected a connected motor at its
output when the Start order has been given. The protection is
enabled setting the parameter Pr.31 to a value different to 0 ‘NONE’.
Slot 1 Fail. The optional board located in the slot1 has been
extracted or there is no possible communication.
STO. Automatic internal protection of several of the IGBT
semiconductors has acted or the safe stop contact of the drive
(connected to an external circuit by the user) has been activated (for
example, emergency stop).
BX: One of the digital inputs (In.65-In.71) has been enabled
configured as 1 ‘DIS START’, forcing the drive to cut the output
supply and making it stop due to inertia.
LV. The drive trips when the voltage within the DC bus is under the
detection level. Therefore, the torque generated can be insufficient
or the motor can be overheated if the input voltage decreases.
Lost command. The drive trips due to a loss of speed set point
established by the use of the control or communication terminals.
ADC Error. Analog Input error.
Shown upon detection of an error in the EEPROM memory or the
analogue input, or when a micro-controller internal fault is detected
(
Watchdog-1 Err, Watchdog-2 Err ).
IO board fault. Displayed when the I/O board or external
communication card is not connected to the drive or there is a bad
connection.
