Setting method of the rotation speed and torque limiting value
The setting method can be selected using the "Speed, torque limiting command selection" parameter. Refer to the table below
for four types of parameter setting methods.

Calculation method of speed reduction ratio:
"Speed reduction ratio" parameter (ID: 2033), "Speed
reduction ratio digit setting" parameter (ID: 2038)
Set using the "Speed reduction ratio" parameter (ID: 2033) and "Speed reduction ratio digit setting" parameter (ID: 2038).
In the case of motors with the
JH
gearhead, the
JB
gearhead, and the
JV
gearhead, input the actual gear ratio into the gear
ratio of the gearhead. Check the operating manual of the motor for the actual gear ratio.
To display the rotation speed for the gearhead gear ratio

Example)
When the speed reduction ratio 15 is set
Set 150 to the "Speed reduction ratio" parameter and 1 to the "Speed reduction ratio digit setting" parameter.
15 that was calculated by the formula "150 x 0.1" was set.
At this time, one-fteenth speed of the motor rotation speed is displayed.
For example, when the motor rotation speed is 1300, "86.6" is shown on the display.
To display as the conveyor transfer speed
To display the conveyor transfer speed, calculate the conveyor speed reduction ratio by using
the formula below and set to the "Speed reduction ratio" parameter.

When the calculated conveyor speed reduction ratio is used, the conveyor transfer speed is
converted as follows.

From the conversion formula, the conveyor speed reduction ratio is calculated as 63.7 in this example.
If the conveyor speed reduction ratio is 63.7 and the rotation speed of the motor is 1300 r/min, the conveyor transfer speed is
converted as follows:

Accordingly, "20.4" is shown on the display.
