Data
Description
Display scale
10 to 100
・
Set the scale of the load ratio to the actual load.
・
Setting 50% changes the result as follows.
Number of moving
average
sampling times
1 to 50
・
Set the number of sampling times for
calculating the moving average (average of
the latest sampling values) of the load
detected by the Shock Monitor.
・
This moving average value is assumed as the
load ratio and used for monitoring, LCD
display, and analog output.
・
Increasing the number of sampling times
reduces the display fluctuation; however, it
takes the following period at the longest for
level detection.
Motor power supply frequency: 50 Hz or more
Detection time = 20 ms x (Setting value of Parameter 16)
Motor power supply frequency: Less than 50 Hz
Detection time = 1 cycle x (Setting value of Parameter 16)
IH
・
Load monitoring is disabled while the input
signal IH is ON. The load ratio display
shows flashing 0%.
・
When the input signal IH turns OFF and the
load ratio has reached or exceeded the setting
level for the Shock Time period or longer, the
relay output is activated immediately.
0.1 to 10.0 s
・
When the input signal IH turns from OFF to
ON, load monitoring is disabled within this
specified time.
・
After the process switching signals X1, X2, and
X3 are changed, load monitoring is disabled
within this specified time.
・
When this specified time elapses and the load
ratio has reached or exceeded the setting level
for the Shock Time period or longer, the relay
output is activated immediately.
(1)On
When the Shock Monitor detects the change in
the motor power supply frequency and the
frequency continues changing at the rate of 4
Hz or higher per second, inhibit function is
activated regardless of the inhibit time setting.
(2)Off
The Auto Inhibit is disabled.
(1)POWER
・
Load is monitored based on the input
electric power value of the motor.
(2)TORQUE
・
Load is monitored based on the torque value
calculated from the motor's input electric
power and motor current frequency.
