Speed reduction ratio
Gr-r
When setting the speed reduction ratio with
respect to the rotation speed of the motor output
shaft, the speed being converted by the speed
reduction ratio can be displayed. If the conveyor
speed reduction ratio is calculated and input, the
conveyor transfer speed can also be displayed.
1.00 to 9999 1.00
Speed increasing ratio
Sp-r
When increasing the motor rotation speed
using the external mechanism and others, the
converted speed can be displayed.

In the speed stability of this product, the display
of the last digit on the rotation speed monitor may
not be stable. If the last digit is xed to "0," the
display status becomes stable.

Prevention of operation at
power-on alarm
opAL
If the power is supplied when the FWD input or
REV input is being ON, an alarm will generate.
When starting or stopping the motor by ON-OFF
control of the power supply, set this parameter to
OFF (Disable).

Note
•
Do not turn the control DC power supply while the display is blinking after executing the data setting or
initialization. Doing so may damage the data.
•
When setting the speed increasing ratio to 1.00, the speed reduction ratio will be effective. When setting the
speed increasing ratio to other than 1.00, the speed increasing ratio will be effective.
