Control device and control system

A control system comprising:

• a motor driver adapted to drive a motor;
• and
• a control device adapted to output a command value to the motor driver;
• wherein
• the control device comprises
• a storage portion adapted to store one or more commands for specifying a behavior of the motor driven by the motor driver, and
• a processing portion including a first arithmetic circuit and a second arithmetic circuit, and
• the first arithmetic circuit is adapted to execute a first process for successively interpreting the one or more commands stored in the storage portion and for successively calculating a parameter set which defines a function relating to calculation of the command value, and
• the second arithmetic circuit is adapted to execute a second process for calculating the command value based on the successively-calculated parameter set, in each predetermined control cycle, independently of the first process.
