6.5 Direction of Axis Speed Reference P20
6 - 12 en-938818/8
Category Servo-control
Type 6 32-bit hexadecimal
No. of words 1
Description
Used to reverse the direction of the axis speed reference sent to the axis servo-drive.
Principle
The bit position gives the physical axis address.
If the bit is a 1, a positive speed reference applied to the servo-drive results in a negative movement of the axis.
Example
The axes at addresses 0 to 6 move in the negative direction for a positive speed reference.

UNI-TE request (see UNI-TE Protocol User’s Manual)
The speed reference direction can be modified by a UNI-TE request. A reset (CNC reset) resets the CNC to the state
specified by P20.
REMARK: For DISC NT, this parameter is located in the servo-drive.
