Digital Output Function Description

Value

 

 

 

 

Output overload warning. OLW is activated when the servo drive has detected that the

 

 

motor has reached the output overload level set by parameter P1-56.

 

 

tOL = Permissible Time for Overload x setting value of P1-56

 

 

When overload accumulated time (continuously overload time) exceeds the value of

 

 

tOL, the overload warning signal will output, i.e. DO signal, OLW will be ON. However,

 

 

if the overload accumulated time (continuously overload time) exceeds the permissible

 

 

time for overload, the overload alarm (ALE06) will output.

OLW

10

For example:

If the setting value of parameter P1-56 (Output Overload Warning Level) is 60%, when

 

 

the permissible time for overload exceeds 8 seconds at 200% rated output, the

 

 

overload fault (ALE06) will be detected and shown on the LED display.

 

 

At this time, tOL = 8 x 60% = 4.8 seconds

 

 

Result:

 

 

When the drive output is at 200% rated output and the drive is continuously

 

 

overloaded for 4.8 seconds, and the overload warning signal will be ON (DO code is

 

 

10, i.e. DO signal OLW will be activated). If the drive is continuously overloaded for 8

 

 

seconds, the overload alarm will be detected and shown on the LED display (ALE06).

 

 

Then, Servo Fault signal will be ON (DO signal ALRM will be activated).

 

 

 

WARN

11

Servo warning activated. WARN is activated when the drive has detected Reverse

limit error. Forward limit error, Emergency stop, Serial communication error, and

 

 

Undervoltage these fault conditions.

CMDOK

12

Internal position command completed. CMDOK is activated when the servo drive has

detected that the internal position command has been completed or stopped after the

 

 

delay time which is set by the parameter P1-62 has elapsed.

 

 

 

NOTE

1) When P2-18 to P2-22 is set to 0, it indicates output function is disabled.
