5) When display shows:
Forward limit switch error:
Please check if any of digital inputs DI1~DI6 signal is set to “Forward inhibit limit (CCWL)” and check if
the signal is ON or not.
Corrective Actions:
„ If it is no need to use “Forward inhibit limit (CCWL)” as input signal, the users only need to
confirm that if all of the digital inputs DI1~DI8 are not set to “Forward inhibit limit (CCWL)”. (The
setting value of parameter P2-10 to P2-15 is not set to 23.)
„ If it is necessary to use “Forward inhibit limit (CCWL)” as input signal, the users only need to
confirm that which of digital inputs DI1~DI6 is set to “Forward inhibit limit (CCWL)” and check if
the digital input signal is ON (It should be activated).
When “Digital Input 1 (DI1)” is set to Servo On (SON), if DI1 is set to ON (it indicates that Servo On
(SON) function is enabled) and the following fault message shows on the display:
6) When display shows:
Overcurrent:
Corrective Actions:
„ Check the wiring connections between the servo drive and motor.
„ Check if the circuit of the wiring is closed.
„ Remove the short-circuited condition and avoid metal conductor being exposed.
7) When display shows:
Undervoltage:
Corrective Actions:
„ Check whether the wiring of main circuit input voltage is normal.
„ Use voltmeter to check whether input voltage of main circuit is normal.
„ Use voltmeter to check whether the input voltage is within the specified specification.
8) When display shows:
