Variable signaling functions

5620 PROG_SIGNAL_FLAGS
Variable signaling function bits
Bit 0= 0: Variable signaling function; not active
1: Variable signaling function; active
Bit1= 0: Variable signaling function segment; address
space X
1: Variable signaling function segment; address
space Y
Bit 2=0: Compar. var. sign. fct.; compare without sign
1: Compar. var. sign. fct.; compare with sign
Unit: Default:
HEX 0
4-154
Minimum: Maximum:
0.0 120 000.0
A message is activated if the manipulated voltage at the D/A converter is contin-
uously for at the limit a set period and, at the same time, the actual velocity is
lower than a set threshold (MD 5606).
Minimum: Maximum:
1 100
The valve spool position is returned for all Rexroth servo solenoid valves from
the preferred range (see Subsection 2.3.2). The message "Valve spool is not
responding" is output if the valve spool position exits the tolerance field of 10%
of maximum stroke around the setpoint for longer than the time set in MD 5614
when the power is enabled. This error message cannot be output if no check-
back signal is configured for the valve spool position (MD 5530).
Input bit field for controlling the variable signaling function.
Minimum: Maximum:
0 7
Note
Bit 1 is only effective, if the signal number 0 is selected in
MD 1651:PROG_SIGNAL_NR.
