What is the operation mode of each control mode in the standard amplifier ?
(Explosion-proof Motor)
【Current control】 (= torque control)
While speed control is constant speed and torque (force) changes, current control is constant torque and speed changes.
Therefore, in order to increase the speed to infinity when the torque is 0, the upper limit speed is set in advance as a parameter.
If you want to press with a certain force, or light torque is high speed, heavy torque is used in machines that you want to slow.
【Speed current position control】
It is used when you want to switch freely with external signals for speed, current and position with one device.
【Direct field】
This function is often used for transfer machines.
The four types of speed set in advance by parameters are switched with external signals and used.
It is used for transfer machines because it has many specific specifications.
【Draw control】
Draw control is often used for tension control, and like a rolling mill or rolling wire, the line roll speed and the next roll speed are changed at a set ratio when the work passes between multiple rolls and rolls.
It is a control method that gives a tension.
