19689 Retraction direction for the second rotary axis
[Data type] Byte
[Valid data range] 0 to 1
Set the direction in which the second rotation axis rotates as a mechanical
motion when a positive move command is issued.
0: Clockwise direction as viewed from the negative to positive direction of
the axis specified in parameter No. 19687 (right-hand thread rotation)
1: Counterclockwise direction as viewed from the negative to positive
direction of the axis specified in parameter No. 19687 (left-hand thread
rotation)
Normally, 0 is set for a tool rotation axis, and 1 is set for a table rotation axis.

When the second rotation axis is a hypothetical axis (bit 1 (IA2) of parameter
No.19696 is 1), set the rotation angle.

[Data type] Bit
# 0 IA1
0: The first rotation axis is an ordinary rotation axis.
1: The first rotation axis is a hypothetical axis.
If IA1 is 1, set 0 as the controlled-axis number for the first rotation axis
(parameter
No. 19681).
Also, set parameter No.19682 to 19685 on the assumption that there is a
rotation axis.
# 1 IA2
0: The second rotation axis is an ordinary rotation axis.
1: The second rotation axis is a hypothetical axis.
If IA2 is 1, set 0 as the controlled-axis number for the second rotation axis
(parameter No. 19686).
Also, set parameter No. 19687 to 19690 on the assumption that there is a
rotation axis.

- Page 41 General On the 5 axis machine which has 2 rotary axes, this function can compensate the thermal growth error along the tool direction which is specified by rotary axes angle. The thermal growth error value is input to CNC by using input signals from PMC. Distribution of heat A A After heart shrink
- Page 52 Description Basic Procedure Thermal growth compensation is input by following method. 1. The PMC drives the start signal THML high and sets the Thermal growth compensation data signals THD00 to THD15. 2. The PMC then drives the strobe signal THSTB high. 3. When THSTB goes high, the control unit re
- Page 6If a large compensation is applied at a time, an excessive error will occur. So, to apply a large compensation, the operation must be divided into several input steps. When the sign of the thermal growth compensation data is positive, this function is treated as an extension of tool length. When the
