3. Controller Functions
3.2.2 Digital Speed Command Value (option)
The "digital speed command value" enables a task to be matched to the
specific plant requirements.
The speed command value can be transferred directly from the PLC
controller, binary or floating-point coded, depending on the required
speed resolution. The parallel signals are interrogated by the control unit
every 1.2 ms.
In plants with severe interference, and in the case of long lines, digital
parallel transmission ensures high speed command value accuracy.
Speed command value resolution:
binary coded 1 rpm
floating-command coded to 0.0005 rpm
The control unit must be fitted with the digital command value interface
(type code field "speed command value = D").
The maximum speed of the motor MAX RPM is not exceeded, even with
excessively high speed command values!
