Restrictions
• The error "Continuous path control not possible" (error code: 1A1EH) will occur and the operation cannot start if
"continuous positioning control" or "continuous path control" is set in "[Da.1] Operation pattern".
• "Position-speed switching control" cannot be set in "[Da.2] Control method" of the positioning data when "continuous path
control" has been set in "[Da.1] Operation pattern" of the immediately prior positioning data. (For example, if the operation
pattern of positioning data No.1 is "continuous path control", "position-speed switching control" cannot be set in positioning
data No.2.) The error "Continuous path control not possible" (error code: 1A1EH) will occur and the machine will carry out a
deceleration stop if this type of setting is carried out.
• The software stroke limit range is only checked during speed control if the "1: Update feed current value" is set in "[Pr.21]
Feed current value during speed control". The software stroke limit range is not checked when the control unit is set to
"degree".
• The error "Software stroke limit +" (error code: 1993H) or "Software stroke limit -" (error code: 1995H) will occur and the
operation cannot start if the start point address or end point address for position control exceeds the software stroke limit
range.
• Deceleration stop will be carried out if the position-speed switching signal is not input before the machine is moved by a
specified movement amount. When the position-speed switching signal is input during automatic deceleration by
positioning control, acceleration is carried out again to the command speed to continue speed control. When the position-
speed switching signal is input during deceleration to a stop with the stop signal, the control is switched to the speed control
to stop the machine. Restart is carried out by speed control using the restart command.
• The warning "Speed limit value over" (warning code: 0991H) will occur and control is continued by "[Pr.8] Speed limit value"
if a new speed exceeds "[Pr.8] Speed limit value" at the time of change of the command speed.
• If the value set in "[Da.6] Positioning address/movement amount" is negative, the error "Outside address range" (error
code: 1A30H) will occur.
• Set WITH mode in the output timing at M code use. The M code will not be output, and the M code ON signal will not turn
ON if the AFTER mode is set.
