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

Analog setting
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.
Combine the ON/OFF statuses of M0 to M2 inputs to select operation data No. 0 or 1.
3.
Connect an external potentiometer or external DC voltage to pins 4 to 6 of the analog I/O
connector (CN6).
Refer to p.42 for details on the connection method.
4.
Set the gain.
Set the torque limit value per 1 V of voltage command in the application parameter for analog torque
limit gain [APP-2-03].
Setting range: 0 to 300%
Initial value: 30%
5.
Adjust the offset.
If there is even a slight margin of error in the voltage value, the torque limit value may not become 0%
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 input terminal (pin 5 of CN6).
3. Apply the offset for analog torque input using the OPX-2A or MEXE02.
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 torque limit offset voltage [APP-2-05].
6.
Use an external potentiometer or external DC voltage to set the torque limit value.
