SBT start position

(control axis)

This signal is used to indicate the position of the safe brake test start of the external brake test or the motor brake test.

This signal saves the current position on the machine coordinate at the start of the safe brake test.

This data is updated at the execution of the safe brake test. (The same value continues to be output unless the safe brake

test is executed.)

The output unit differs depending on the parameter "#1040 M_inch" (Constant input (inch)).

If the target axis is an rotary axis, the output unit is 0.0001° regardless of the parameter "#1040 M_inch" (Constant input

The output unit is submicron (0.0001mm).

(Example) When the machine position of the 1st axis (linear axis) is 123.4567 mm

Machine position

The output unit is 0.00001 inch.

(Example) When the machine position of the 1st axis (linear axis) is 1.23456 inch

Machine position 1.23456

The output unit is 0.0001°.

(Example) When the machine coordinate of the 1st axis (rotary axis) is 1.23456°
