6.3.1.5 Format signal 6 / 8: Speed value A / B (NIST_A / B)
The speed is output as a two's complement value with preceding sign.
Code sequence setting = Rising
rising position values at bar end:
--> positive speed output
Code sequence setting = Falling
falling position values at bar end:
--> negative speed output
The unit is set via the
Velocity measuring unit
parameter (PNU 60001), see page 126. The
default setting is
mm/s

Preset mode
Defines whether the measuring system position value is set to the preset
value or if it should be offset by this value.
0: Position value is set to the preset value (absolute)
1: Position value is offset by the preset value (relative = offset)
no
yes

Execute preset according to preset mode
The preset value is set with a rising edge 0->1. The exact procedure is
described in chapter "Preset function" on page 145. In the default setting
signal
G1_XIST1
remains unaffected, see parameter
