Chapter 9. How to Use Torque Servo

9.5.1 Inputting digital speed limit
The following is how to input 3 digital speed commands. First, move to [Speed Mode (P3--)],
the speed-related parameter group, from the main menu. Then, input the desired digital
speed command in [RPM]. Speed limit does not have any relation with codes.
Absolute values are used regardless of positive value or negative value. To prevent
confusion, always use the positive value.

9.5.2 Inputting analog speed limit
To input analog speed limit, apply a voltage between -10[V] and 10[V] to the analog input
terminal (SPDIN). The speed limit used inside the servo can be adjusted as follows
according to the absolute value of the voltage of the analog input (SPDIN) and the set values
of [10V Speed (P3-13)], [SPD CMD OFFS (P3-14)].

9.6 Inputting Torque Command
The torque command can be input to the analog input terminal (TRQIN). Apply a voltage
between -10[V] - 10[V] to (TRQIN). The torque command and voltage have the following
relationships.
