Direction of spindle

With MP3130, define the polarity of the nominal speed value

In MP3140, enter the counting direction of the position encoder signals.

As soon as you set M4005 for M03, or M4006 for M04, the nominal speed

value is output. With M4007 for M05, the nominal speed value zero is output

(spindle stop).

M4005 to M4007 also controls the miscellaneous functions in the status

If more than one marker is set at the same time, the error message PLC:

M4005, M4006, M4007 INCORRECT appears.

With M4014 you can reverse the direction of rotation, in order to adjust the

transmission for horizontal or vertical spindles, for example. The polarity of the

nominal spindle speed is inverted.

M4019 reverses the counting direction of the spindle.

Polarity of the nominal spindle speed

0: M03 positive, M04 negative

1: M03 negative, M04 positive

2: M03 and M04 positive

4: M03 and M04 negative

Counting direction of spindle position encoder output

0: Positive counting direction with M03

1: Negative counting direction with M03
