Digital frequency – slave (cascade) (C0005 = 7000)
The configuration C0005 = 7000 is used to integrate the drive controller into a drive system.
The drive is controlled by reading in the digital frequency setpoint via input X9. This value is then
evaluated and the speed of the drive is adapted to the process based on the result of the evaluation.
An internal additional setpoint can also be activated via digital input X5/E3.
Unlike in configuration 6000, the evaluated control setpoint is forwarded via digital frequency output
X10. This means that changes in the evaluation also affect subsequent drives.
Fig. 2−10 shows the basic structure of a digital frequency network for textile machinery.
