Description
When the overtemp detection device of the brake unit and brake resistor
(optional) or the user’s external thermal relay is activated, the inverter will
stop output and hold the fault trip (motor coasts to stop).
If the inverter CPU operation is abnormal, the inverter will stop output and
hold the fault trip (motor coasts to stop).
When low limit frequency setting exceeds that of the high limit frequency.
When a Function Code that cannot be set while inverter is running has been
attempted to be set.
Stored setting data is abnormal. This error message cannot be reset.
Replace the Main Control Card.
NOTE: may be possible to c/ear this condition by removing and
reinserting any socketted integrated circuit chips on the Main Card
of three).
Automatically extends acceleration time to restrict overcurrent during rapid
acceleration (to prevent overcurrent trip).
Automatically extends deceleration time to restrict overcurrent and over-
voltage during rapid deceleration (to prevent overcurrent and overvoltage
trip).
The inverter can be protected from standard impact wave voltage which
will invade from the main circuit power.
