Chapter 7 Servo Parameters
Setting value: 0x08
DO Name
Electromagnetic brake control. BRKR is activated
(Actuation of motor brake). (Please refer to
parameters P1-42 ~ P1-43)
BRKR
Setting value: 0x10
DO Name
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
OLW
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,
