MC_MoveVelocity, MCP_MoveVelocity –  Move with constant velocity

Block SymbolsLicensing group: MOTION CONTROL
PIC PIC

Function Description

The MC_MoveVelocity and MCP_MoveVelocity blocks offer the same functionality, the only difference is that some of the inputs are available as parameters in the MCP_ version of the block.

The MC_MoveVelocity block changes axis velocity to specified value as fast as possible and keeps the specified velocity until the command is aborted by another block or event.

Note: parameter Direction enumerate also shortest_way although for this block it is not valid value.

Inputs

uAxis

Axis reference (only RM_Axis.axisRefuAxis or yAxisuAxis connections are allowed)

Reference

Execute

The block is activated on rising edge
