P1 - 56
OVW
Output Overload Warning Time
Communication Addr.: 0138H
Default: 120
Related Section: N/A
Applicable Control Mode: ALL
Unit: %
Range: 0 ~ 120
Settings:
This parameter is used to set output overload time.
If the setting value of parameter P1-56 is set to 0 ~ 100, the function of parameter P1-56 is
enabled. When the motor has reached the output overload time set by parameter P1-56, the
motor will send a warning to the drive. After the drive has detected the warning, the DO signal
OLW will be activated.
If the setting value of parameter P1-56 exceeds 100, the function of parameter P1-56 is disabled.
tOL
= Permissible Time for Overload x the setting value of parameter 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 (ALE06) 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
(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, the overload warning signal will be ON (DO code is 10, i.e. DO signal OLW will be
activated) and the overload warning (ALE23) will be displayed. 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).
