IK220LatchRef
With the next reference mark, the counter value is saved in
register 2. The saved value is without interpolation and can be
output with IKGet32 or IKGet48.
Prototype: BOOL IK220LatchRef (USHORT Axis);
Axis:
Number of the axis (0 to 15)
IK220Latched
Determines whether the counter value was saved.
Prototype: BOOL IK220Latched (USHORT Axis,
USHORT Latch, BOOL* pStatus);
Axis: Number of the axis (0 to 15)
Latch: 0 = Request for register 0.
1 = Request for register 1
2 = Request for register 2
pStatus: Pointer to a variable in which the status is saved.
False (=0) = value not saved
True (
≠
0) = value was saved
IK220WaitLatch
Waits until the counter value was saved. If no timeout time was
defined, the function waits until a numerical value is saved in
the corresponding latch.
Prototype: BOOL IK220WaitLatch (USHORT Axis,
USHORT Latch);
Axis: Number of the axis (0 to 15)
Latch: 0 = Request for register 0.
1 = Request for register 1
2 = Request for register 2
IK220SetTimeOut
With this function you can define a timeout time. If no timeout
time is defined, the IK220WaitLatch, IK220WaitRef and
IK220PositionRef functions wait until the respective event
occurs.
Prototype: BOOL
IK220SetTimeOut (ULONG TimeOut);
TimeOut: 0 = No timeout
1.. = Timeout in ms
