- if, when tuning the loop, the blue LED does not light up, this could mean that the
motor is not drawing any current.
Possible reasons for this include:
 the motor is not correctly connected or not connected at all:
check the motor cable and the connections by the AUTODETECT MODE
 the motor is at the stroke end:
type a different frequency and tune again
 the motor is faulty:
contact customer support
- If there is no keyboard, you will see the message WAIT KEYBOARD .

AUTO MODE (available only with the optional card I/O RS232 interface).
