Adjustment using a parameter
1. Set the application parameter for analog input signal automatic offset [APP-2-06] to “Disable.”
2. Set the offset voltage in the application parameter for analog speed limit offset voltage [APP-2-02].
7.
Set the speed limit value using an external potentiometer or external DC voltage.

Description
① 550 r/min 0 r/min 0 V
The speed limit value per 1 V of voltage
command becomes 550 r/min.
② 10 r/min 0 r/min 0 V
The speed limit value per 1 V of voltage
command becomes 10 r/min.
③ 550 r/min 0 r/min 1 V
The home position of voltage command
becomes 1 V. The gain of speed limit
value is the same as in example①.
④ 550 r/min 10 r/min 0 V
If the speed limit value is set less than
10 r/min of the voltage command (less
than 1 V), the speed limit value will be
0 r/min.

Digital setting
• When the analog input signal parameter [SyS-1-05] is set to “Enable”
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.
Use the OPX-2A or MEXE02 to set one of operation data Nos. 2 to 7 as the speed command
value.
3.
Combine the ON/OFF statuses of M0 to M2 inputs to select one of operation data Nos. 2 to 7.
• When the analog input signal parameter [SyS-1-05] is set to “Disable”
1.
Set the system parameter for analog input signals [SyS-1-05] to “Disable.”
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.
Use the OPX-2A or MEXE02 to set one of operation data Nos. 0 to 7 as the speed command
value.
3.
Combine the ON/OFF statuses of M0 to M2 inputs to select one of operation data Nos. 0 to 7.
