*1 When the torque change function is used with the individual setting for new torque value and reverse new torque value, it indicates
outside forward new torque value.
*2 This speed is a value in which override value is considered when override function is used. ("[Cd.13] Positioning operation speed
override" is set other than 100 [%].)
*3 The speed change by position-speed switching control, target position change function, or override function is contained.
*4 The speed change by position-speed switching control or target position change function is contained.
Error details and causes
• The speed change value is outside the setting range
when changing the speed during operation
• "[Cd.140] Command speed at speed control mode" is
outside the setting range during the speed control
mode.
• "[Cd.146] Speed limit value at torque control mode" is
outside the setting range during the torque control
mode.
[Operation status at warning occurrence]

Remedy
• Set the speed change value to within the setting
*4
range.
• Set "[Cd.140] Command speed at speed control
mode" to within the setting range during the speed
control mode.
• Set "[Cd.146] Speed limit value at torque control
mode" to within the setting range during the torque
control mode.
Confirm the warning code by "[Md.114] Servo alarm"
and refer to the driver instruction manual for details.
