This property is used to either set or query the SERCOS communications cycle time. Set this value before initializing the SERCOS ring.
Short form
Ser.CTim
Syntax
Sercos.CycleTime = <value>
?Sercos.CycleTime
Availability
All versions
Type
Long
Range
Discrete values of 2000,3000,4000,5000 or 6000. Discrete values of 7 through 16 milli-seconds are also supported, but the drive may not support microinterpolation with these cycle times. Microinterpolation is necessary for smoothing the position profile.
Units
Microseconds
Default
4000 (4 milliseconds)
Scope
Configuration, Task or Terminal
Limitations
- This property is only set in SERCOS communication phases 0, 1, and 2, is transferred from the softMC to drives during phase 2, and becomes active in phase 3
- Not supported in EtherCAT system
Examples
Sercos.CycleTime = 2000
?sercos.CycleTime
