PLCopenPlus Function Blocks for Motion Control 2013-04-13
158
The function block is not applicable for the external axis
specified
A homing sequence is already in progress.
Motion aborted due to axis alarm.
When the axis is in rotary mode, and the MC_SetPosition tries
to set a position that is equal to or greater than the
MachineCycle, this error is generated, and the position is not
set.
Axis must be commanded at standstill when homing is
attempted.
Position cannot be defined while the axis is the cam master of
other axes.
The function block can not be used with a virtual axis.
Axis latch function already in use.
Over travel limit still ON after attempting to move away from it.
Axis ID does not correspond to an axis configured on the
system. Verify the value of AxisNum matches a logical axis
number in the configuration. Tip: Make sure AXIS_REF is
properly declared as a VAR or VAR_GLOBAL in all relevant
POUs.
Direction does not correspond to a valid enumeration value.
Mode does not correspond to a valid enumeration value.
Velocity parameter is less than or equal to zero.
The structure size does not match.
An internal motion kernel command failed. This error could be
caused by inserting multiple MC_Power function blocks in the
program for the same axis. Only one MC_Power function per
axis is required. (Do not include more than one.)
