[Pr.83] Speed control 10 times multiplier setting for degree axis
Set the speed control 10  multiplier setting for degree axis when you use command speed and speed limit value set by the
positioning data and the parameter at "[Pr.1] Unit setting" setup degree by ten times at the speed.
0: Invalid
1: Valid
Normally, the speed specification range is 0.001 to 2000000.000 [degree/min], but it will be decupled and become 0.01 to
20000000.00 [degree/min] by setting "[Pr.83] Speed control 10  multiplier setting for degree axis"
*1 The "Speed control 10  multiplier setting for degree axis" is included in detailed parameters 2. However, it will be valid at the leading
edge (OFF to ON) of the PLC READY signal [Y0].
*2 Refer to the following for details on the speed control 10  multiplier setting for degree axis.

[Pr.84] Restart allowable range when servo OFF to ON
■Restart function at switching servo OFF to ON
The restart function at switching servo OFF to ON performs continuous positioning operation (positioning start, restart) when
switching servo OFF to ON while the Simple Motion module is stopped (including forced stop, servo forced stop).
Restart at switching servo OFF to ON can be performed when the difference between the last command position of Simple
Motion module at stop and the present value at switching servo OFF to ON is equal to or less than the value set in the buffer
memory for the restart allowable range setting.
• Servo emergency stop processing
• When the difference between the last command position of Simple Motion module at the forced stop input or the servo forced stop input and the present
value at the forced stop release or the servo forced stop release is equal to or less than the value set in the buffer memory for the restart allowable range
setting, the positioning operation is judged as stopped and can be restarted.
• When the difference between the last command position of Simple Motion module at the forced stop input or the servo forced stop input and the present
value at the forced stop release or the servo forced stop release is greater than the value set in the buffer memory for the restart allowable range setting, the
positioning operation is judged as on-standby and cannot be restarted.

• When the difference between the last command position of Simple Motion module at switching the servo ON signal from ON to OFF and the present value at
switching the servo ON signal from OFF to ON is equal to or less than the value set in the buffer memory for the restart allowable range setting, the
positioning operation is judged as stopped and can be restarted.
• When the difference between the last command position of Simple Motion module at switching the servo ON signal from ON to OFF and the present value at
switching the servo ON signal from OFF to ON is greater than the value set in the buffer memory for the restart allowable range setting, the positioning
operation is judged as on-standby and cannot be restarted.
