Select a desired speed limit value from among the predefined settings, based on a combination of ON/OFF
statuses of M0 to M2 inputs.

Using the internal potentiometer VR2
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 limit value using the internal
potentiometer VR2.
Setting range: 0 to 5500 r/min
Factory setting: 0 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
limit 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 limit clamp [APP-2-01].
6.
Set the offset.
If there is even a slight margin of error in the voltage value, the speed limit value may not become
0 r/min even when the voltage command specifies 0 V (minimum value). In this case, adjust the offset
using one of the two methods described below.
Automatic adjustment
1. Set the application parameter for analog input signal automatic offset [APP-2-06] to “Enable.”
2. Input 0 V to the analog speed input terminal (pin 1 of CN6).
3. Apply the offset for analog torque input using the OPX-2A or MEXE02.
