94 RESET FAULT Command by FLN to reset a faulted drive
(1 = RESET, 0 = NO).
Parameter 1604 must be set to COMM for FLN to control this
state.
The control input is rising-edge sensitive, so, once the
command is issued, this point automatically returns to its
inactive state. This “momentary” operation avoids any need
for an explicit command to clear the point before a
subsequent reset can be issued.
95 MBOX PARAM Sets the parameter to be used by the mailbox function.
96 MBOX DATA Sets or indicates the data value of the mailbox function.
97 MBOX READ Command by FLN to read the parameter value specified by
Point 95, MBOX PARAM. The parameter value is returned in
Point 96, MBOX DATA.
The control input is rising-edge sensitive, so, once the
command is issued, this point automatically returns to its
inactive state. This “momentary” operation avoids any need
for an explicit command to clear the point before a
subsequent reset can be issued.
98 MBOX WRITE Command by FLN to write the data value specified by Point
96, MBOX DATA, to the parameter value specified by Point
95, MBOX PARAM.
The control input is rising-edge sensitive, so, once the
command is issued, this point automatically returns to its
inactive state. This “momentary” operation avoids any need
for an explicit command to clear the point before a
subsequent reset can be issued.
99 ERROR STATUS 1 of the 5 mandatory FLN points required for compatibility
with Siemens control systems. It has no functionality in the
