The max torque measurement method for the Stall Torque and Performance Graph are different. Stall torque is measured from the max torque that it can reach. This is generally how
traditional RC servos measure maximum torque. The Performance graph which is also called the N-T Curve, measured by gradually increasing the load. The actual motor operating
environment is similar to the performance graph, not stall torque measurement method. For this reason, the performance graph is broadly used in the industrial market. Generally the max
torque of the performance graph is measured smaller than the stall torque.
Precautions when connecting to power supply!
- For a stable power supply, it is recommended using ROBOTIS controller or SMPS2Dynamixel.
- Connect your DYNAMIXEL to power supply while it’s off and turn on/off with the power switch.
Control Table
The Control Table is a structure of data implemented in the Dynamixel. Users can read a specific Data to get status of the Dynamixel with Read Instruction Packets, and modify Data as well to control
Dynamixels with WRITE Instruction Packets.
Control Table, Data, Address
The Control Table is a structure that consists of multiple Data fields to store status of the Dynamixel or to control the Dynamixel. Users can check current status of the Dynamixel by reading a specific
Data from the Control Table with Read Instruction Packets. WRITE Instruction Packets enable users to control the Dynamixel by changing specific Data in the Control Table. The Address is a unique
value when accessing a specific Data in the Control Table with Instruction Packets. In order to read or write data, users must designate a specific Address in the Instruction Packet. Please refer to the
for more details about Packets.
Note : Two's complement rule is followed to find the negative value.
For more information, please refer to the following link (
Area (EEPROM, RAM)
The Control Table is divided into 2 Areas. Data in the RAM Area is reset to initial values when the Dynamixel is turned on (Volatile). On the other hand, modified data in the EEPROM Area keeps their
values even when the Dynamixel is turned off (Non-Volatile). Data in the EEPROM Area can only be changed when the value of Torque Enable(64) is cleared to ‘0’.
Access
The Control Table has two different access properties. ‘RW’ property stands for read and write access permission while ‘R’ stands for read only access permission. Data with the read only property
cannot be changed by the WRITE Instruction. Read only property(‘R’) is generally used for measuring and monitoring purpose, and read write property(‘RW’) is used for controlling Dynamixels.
Initial Value
Each data in the Control Table is restored to initial values when the Dynamixel is turned on. Default values in the EEPROM area are initial values of the Dynamixel (factory default settings). If any
values in the EEPROM area are modified by a user, modified values will be restored as initial values when the Dynamixels is turned on. Initial Values in the RAM area are restored when the
Dynamixels is turned on.
Size
The Size of data varies from 1 to 4 bytes depend on their usage. Please check the size of data when updating the data with an Instruction Packet.
