Output Overload Warning Level - Delta Electronics AC Servo Drive ASDA-AB User Manual

P1 - 56 OVW

Output Overload Warning Level

Default: 120
Applicable Control Mode: ALL
Unit: %
Range: 0 ~ 120
Settings:
This parameter is used to set output overload level. When the motor has reached the output
overload level 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.
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 overload
accumulated time (continuously 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 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, 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, and the overload warning signal will be ON (DO code is 10, i.e. DO signal OVW 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).
