Using the internal potentiometer VR1
1.
Set the system parameter for analog input signals [SyS-1-05] to “Enable.”
Note
When a system parameter has been changed, the new parameter will become
effective after the power is cycled. If a 24 VDC power supply is used, also cycle the
24 VDC power supply.
2.
Turn the M0 to M2 inputs OFF and select operation data No. 0.
3.
Set the speed command using the internal
potentiometer VR1.
Setting range: 0 to 5500 r/min
Factory setting: 0 r/min
VR1
4.
Set the acceleration/deceleration time using the
internal potentiometer VR2.
The acceleration time and deceleration time are the
same.
Setting range: 5 to 10000 ms / (1000 r/min)
Factory setting: 5 ms / (1000 r/min)

Using an external potentiometer or external DC voltage
1.
Set the system parameter for analog input signals [SyS-1-05] to “Enable.”
Note
When a system parameter has been changed, the new parameter will become
effective after the power is cycled. If a 24 VDC power supply is used, also cycle the
24 VDC power supply.
2.
Turn the M0 input ON and M1 and M2 inputs OFF, and select operation data No. 1.
3.
Connect an external potentiometer or external DC voltage to pins 1 to 3 of the analog I/O
connector (CN6).
Refer to p.42 for details on the connection method.
4.
Set the gain.
Set the speed command value per 1 V of voltage command in the application parameter for analog speed
command gain [APP-2-00].
Setting range: 0 to 5500 r/min
Initial value: 550 r/min
5.
Set the minimum speed.
To clamp all speed command values below a certain speed at 0 r/min, set the application parameter for
analog speed command clamp [APP-2-01].
