P1 - 56 OVW
Default: 120
Applicable Control Mode: ALL
Unit: %
Range: 0 ~ 120
Data Size: 16-bit
Display Format: Decimal
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.
t OL = Permissible Time for Overload x the setting value of parameter P1-56
When overload accumulated time (continuously overload time) exceeds the value of t OL ,
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, 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).
