WARNING
4.6.2 Digital inputs sample times
The digital I/O sample times for the control terminals are shown in Default configuration on page 111. These times are correct
but are the times for the control microprocessor to sample the digital inputs. The actual time for the drive to act upon these
signals will be slightly longer.
The digital input will be sampled within 1.5ms, then it takes between 4.5 to 6ms for this information to be passed across the
serial communications link between the control microprocessor and the machine control DSP (Digital Signal Processor). The
DSP runs on a 6kHz cycle and the information is processed as soon as it receives the information from the serial comms link.
Example:
The maximum time taken to disable the drive:
Control microprocessor update rate: 1.5ms maximum
Time across serial comms link and DSP to process information: 6.0ms maximum
Therefore it will take a maximum of 7.5ms for the drive to disable from receiving the disable signal.
4.6.3 Digital output update rate
The time taken for the digital output to be updated will depend upon the parameter programmed to the digital output source
(parameter 8.21). The DSP is run on a 6kHz cycle and the information is passed across the serial comms link on this cycle
time.
Example:
The maximum update time for the drive healthy relay to be set:
DSP to process information and time across the serial comms link: 6.0ms maximum
Control microprocessor update rate: 1.5ms maximum
Therefore it will take a maximum of 7.5ms for the drive healthy relay to be set to indicate a fault.
