介绍下Parker Compax3是如何实现上述功能的,该产品能从位置控制模式直接转换到力矩控制模式,也能从力矩控制模式直接转换到位置控制模式。中间无需力矩降低到0的过程。
C3_TorqueControl
Torque / force control with speed limitation
The module can be started from the "Discrete Motion" and "Continuous Motion" states. The position control is deactivated during this operating mode.
The movenemnt is limited by the set maximum speed or by the command torque/command force.
The actual speed value is always positive.
The direction of movement depends on the Direction Input.
There is no torque/force acquisition. Actual torque or actual force is acquired from the quadrature current and the motor parameters.
Behaviour on
Stop: (MC_Stop) => immediate switching to position control; this means entire torque (or entire force)!
C3 error => depending on the error reaction (1) switching to position control, this means entire torque (or entire force)!
The module can also be used for defined braking, e.g. for unwinders.
The command torque or the command force has then the opposite sign than the direction
If there is no counter torque or no counter force, so that braking is not possible, the drive will decelerate to 0 in a torque/force controlled manner.
