Restrictions
(1) Set "Positioning complete" for "
Da.1 Operation pattern." If "continuous
positioning control" or "continuous path control" is selected, an error
"continuous path control not possible" (error code: 516) occurs, resulting in a
failure to start. (In the speed control mode, "continuous positioning control" or
"continuous path control" cannot be selected.)
(2) To use M codes, set the "WITH" mode for "
Pr.19 M code ON signal output
timing." If the "AFTER" mode is selected, the M codes are not output and the
"M code ON" signal does not turn ON.
(3) The current speed (-1) cannot be set for "
Da.7 Command speed." If the
current speed is set, an error "no command speed" (error code: 503) occurs.
(4) The software stroke limit check is not made with the "degree" unit.
(5) When the absolute position restoration mode is the "infinite length mode",
executing speed control with other than "1" set to "
Pr.22
Current feed value
during speed control" results in an error "control method setting error" (error
code: 524).
