Update Rate Types

Update Rate Type	Description
Controller	The update rate depends on KAS Kollmorgen Automation Suite application program The act of performing a sequence of instructions or commands. update rate. See Define the PLC Cycle.
EtherCAT Ethernet ofr Control Automation Technology. EtherCAT® is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT is to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. Cyclic	The update rate depends on the EtherCAT. See these topics about update rates: EtherCAT Master Settings tab Define the PLC Cycle
EtherCAT Non-Cyclic	The update rate depends on the reading of the parameter through EtherCAT.
Static	The Values do not change after the axis is created.

User Units to Feedback Units Ratio

Parameters Non-Boolean Parameters and Non-Boolean Parameters are set during the MC_CreatePLCAxis function block A function block groups an algorithm and a set of private data. It has inputs and outputs. execution.

• These two parameters work together to form the User Units to Feedback Units Ratio (UU/FBU Ratio).
• The drive In electrical engineering, a drive is an electronic device to provide power to a motor or servo. Control device for regulating the speed, torque and position of a motor. A unit controlling a motor using the current and timing in its coils. interface units are fixed by the drive and define the drive units per revolution.
  • This is used to command the drive per the ratio.

Example 1

Where the drive interface units are set to 1048576 units per revolution, the value of the UU-per-revolution ratio is calculated as:

UU per revolution = MC_AXIS_PARAM_UU_FB_RATIO_NUM * 1048576 / MC_AXIS_PARAM_UU_FB_RATIO_DEN

Example 3 - Reading the Current to Units of Amps

After reading the current using MC_ReadParam, this equation converts current to amps for a 12 amp peak drive:
