4950 IMB ESI TRV ISZ IDM IOR
[Data type] Bit
IOR Resetting the system in the spindle positioning mode
0: Does not releases the mode.
1: Releases the mode
IDM The direction of half-fixed angle spindle is:
0: Plus direction.
1: Minus direction.
ISZ When the M code specifying orientation is specified in spindle
positioning, the spindle rotation mode is switched to the spindle
positioning mode and then orientation is:
0: Performed.
1: Not performed.
TRV The rotation direction of spindle positioning is:
0: The same as the normal direction.
1: Reversed.
ESI Spindle positioning conforms to:
0: The conventional specifications.
• The number of M codes used for the semi-fixed angle
spindle positioning command is fixed to six.
• The upper limit of spindle positioning feedrate setting
(parameter No. 1420) is 240000 (10 deg/min).
1: The extended specifications.
• The number of M codes used for the semi-fixed angle
spindle positioning command can be selected from 1 to 256
by setting parameter No. 4964.
• The upper limit of spindle positioning feedrate setting
(parameter No. 1420) is 269000 (10 deg/min).
IMB The semi-fixed angle spindle positioning command conforms to:
0: The A specification.
1: The B specification.
Spindle positioning after execution of the semi-fixed angle command
consists of the following three operations.
1) Release the spindle rotation mode and enter the spindle
positioning mode.
2) Perform spindle positioning.
3) Release the spindle positioning mode and enter the spindle
rotation mode.
For the A specification, specify a separate M code for each operation.
1) Specify an operation with the M code (parameter No. 4960) for
specifying orientation.
