CANOPEN.SAMPLEPERIOD
Description
This parameter sets the fieldbus sample period (cyclic rate) which is the time between two PDO updates on the fieldbus cyclic channel. Use CANopen objects 60C2 subindex 1 (interpolation time period value) and 2 (interpolation time index) to adjust the CANOPEN.SAMPLEPERIOD over the fieldbus.
Formula:
SamplePeriod (seconds) = Interpolation_Time_Period_Value x 10^ Interpolation_Time_Index
For example, SamplePeriod = 1 x 10 -3 seconds, and this will set CANOPEN.SAMPLEPERIOD = 1000 microseconds. Kollmorgen recommends the following standard cycle rates, 250 µs, 500 µs, 1000 µs, 2000 µs, or 4000 µs.
Examples
Usage
For EtherCat:
The sample period must match the SYNC 0 period when using Distributed Clocks. The drive will not transition to OPERATIONAL mode when the SYNC 0 does not match the sample period.
