OLW
Output overload warning. OLW is activated when the servo
drive has detected that the motor has reached the output
overload time set by parameter P1-56.
t
OL = 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
accumulated overload time (continuous overload time)
exceeds the permissible time for overload, the overload
alarm (AL006) will occur.
For example:
If the setting value of parameter P1-56 (Output Overload
Warning Time) is 60%, when the permissible time for
overload exceeds 8 seconds at 200% rated output, the
overload fault (AL006) will be detected and shown on the
LED display.
At this time,
t
OL = 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, the overload
warning signal will be ON (DO code is 0x10, 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 (AL006). Then,
Servo Fault signal will be ON (DO signal ALRM will be
activated).
