Function extension:
So far, for the 8400 motec, torque limitation could only be performed with the distinction in motor mode or in generator mode. The limits nTorqueMotLimit and nTorqueGenLimit are available for this.
In the case of an actual speed of 0rpm or when passing 0 speed, the drive changes between the two limitations. This behaviour becomes particularly apparent in the case of very different limitation values (in motor mode: 10%, in generator mode: 100%)
From firmware version 10.00.00, a changeover function has been added with C00143 bit10 = 1 so that the limit values will be interpreted in a different way:
- nTorqueMotLimit acts as nTorqueHighLimit (positive torque limitation in positive and negative direction of rotation)
- nTorqueGenLimit acts as nTorqueLowLimit (negative torque limitation in positive and negative direction of rotation)
With the setting C00143 bit10 = 0, as before, nTorqueMotLimit will be effective for operation in motor mode and nTorqueGenLimit for operation in generator mode.
The limitation can be used for all control types.
