2-5 Gain adjustment and oset adjustment for rotation speed
If the gain or oset is adjusted when the rotation speed is set using the external potentiometer or external DC voltage, the slope
of the speed command can be changed and the speed can nely be adjusted.
Note
The rotation speed corresponding to the voltage value varies depending on the product.

1821 Analog operation speed command gain
Sets the speed command per 1 VDC of the input voltage by
the external analog setting device.
0 to 4000 r/min 850
1822 Analog operation speed command oset
Sets the oset of the speed command input by the external
analog setting device.
–2000 to +2000 r/min 0
2085 Speed upper limit Sets the upper limit value of the speed command. 50 to 4000 r/min 4000
2086 Speed lower limit Sets the lower limit value of the speed command. 50 to 4000 r/min 50

Setting example 1:
When operating the motor linearly up to the maximum rotation speed of 4000 r/min with external DC voltage
between 0 and 10 VDC
Set the "Analog operation speed command gain" parameter (ID: 1821) to 425.

Setting example 2:
When operating the motor linearly up to the maximum rotation speed of 2000 r/min with external DC voltage
between 0 and 10 VDC
Set the "Speed upper limit" parameter (ID: 2085) to 2000 rst, and set the "Analog operation speed command gain" parameter
(ID: 1821) to 213.
