Motor drive alarm board
If the machine drive stops, control the status LED (fig. B, ref. 13) to identify the error code. In the
absence of malfunctions, the status LED is lit steadily while the machine is in operation. If a
malfunction is detected, the status LED provides two types of information, a slow flash (2 Hz) or a
rapid flash (4 Hz) to indicate the severity of the malfunction.
Malfunctions with a slow flash are cancelled automatically once the malfunction has been repaired
and the machine functions normally again. Malfunctions with a rapid flash ("*" in the table) are
considered more serious. The machine must be turned of using the key switch (fig. B ref. 3) to reset
operation after repairing the malfunction.
The indication of severity remains active for 10 seconds, after which the status LED flashes
constantly showing a two digit malfunction code until the repairs have been carried out.
For example, error code "1,4" is displayed as follows:
