Item Display Description
Rotation speed
*
•
Monitors the rotation speed of the motor.
•
Monitors the rotation speed of the gear output shaft or conveyor transfer speed when the
"speed reduction ratio" parameter is set.
•
When the "speed increasing ratio" parameter is set, the rotation speed being increased by the
external mechanism is displayed.
Load factor
The motor generating torque can be checked. The present load factor is displayed based on the
rated torque being 100%.
The load factor is displayed in 1% increment between 40% and 200%, and "
" is displayed
if the load factor is smaller than 40%.
The display is the load factor on the motor output shaft. It is not for the gearhead output shaft.
In the case of the gearhead output shaft, the permissible torque varies depending on the gear
ratio of the gearhead used.
Use the product so that the load does not exceed the permissible torque of the gearhead
output shaft.
When the slight position-keeping is enabled, "
" is displayed.
Operation data No.
Monitors the operation data No. currently selected.
Alarm
When an alarm generates, the alarm code is displayed. You can also reset alarms or check and
clear alarm records. Refer to p.34 for alarm type.
Warning
When a warning generates, the warning code is displayed. You can also check and clear warning
records. Refer to p.37 for warning type.
I/O monitor
You can check the ON/OFF status of each I/O signal of the driver. If the signal is ON, the
corresponding digit is lit. If the signal is OFF, the digit is unlit.

For the factory setting, the rotation speed is displayed when the power is turned on.
The display for when turning on the power can be changed using the parameter. Panel initial view parameter: p.28
Display of the rotation speed
In the case of motors with the
JH
gearhead, the
JB
gearhead, and the
JV
gearhead, use the actual gear ratio about the
gear ratio of gearhead. Check the operating manual of the motor for the actual gear ratio.
z
Displayed digit number when setting the speed reduction ratio or speed increasing ratio
Since the number of signicant gures for the integer part is changed if the speed reduction ratio or speed increasing
ratio is set, the digit number displayed on the panel will also be changed.
