Explanation of Set Values
• If an alarm occurs with the main power supply OFF, the Servomotor will operate according to the
value set in Stop Selection for Alarm Detection (Pn510). If the main power supply is turned OFF with
the servo ON and Undervoltage Alarm Selection (Pn508) is set to 1, the Servomotor will operate
according to the value set in Stop Selection for Alarm Detection (Pn510) because a Main Power
Supply Undervoltage (AC cut-off detection) alarm (Alarm No. 13.1) occurs.
• The dynamic brake is designed only for immediate stop. Configure the system to stop for about three
minutes after the dynamic brake operates.
*1 “Immediate stop” means stopping the Servomotor immediately by using control with the servo ON.
The torque command value at this time is limited by the value set in Immediate Stop Torque (Pn511).
*2 If the position command is supplied continuously or if the Servomotor rotates continuously with the main power
supply OFF, a Error Counter Overflow (Alarm No. 24.0) may occur due to the accumulation of position errors.
In addition, if the servo turns ON with a large position error, the Servomotor may start moving suddenly
because the control attempts to zero the error. Take extra care when using the Servo Drive with this parameter
set to hold the position error counter content.
*3 “During deceleration” means the period until the motor decreases its speed to 30 r/min or less from the normal
operation. Once the Servomotor decelerates to 30 r/min or lower and falls in an After stopping state, it follows
the operation described under “After stopping,” independent of the actual motor speed.
*4 The position error counter content will be always cleared to zero with these settings.

Set value Description
0 The servo is turned OFF based on the value set in Stop Selection with Main Power Supply OFF
(Pn507). The servo is then turned back ON when the main power supply is turned ON.
1 A Main Power Supply Undervoltage alarm (Alarm No. 13.1) occurs, causing an alarm trip.
