7 Parameter Details
• Set the drive conditions during deceleration and after stopping, when the Forward Prohibition Input
(POT: CN1 pin 9) or Reverse Drive Prohibition Input (NOT: CN1 pin 8) is enabled.
• When set to 2, the torque limit during deceleration is limited by the value set in Immediate Stop
Torque (Pn511).
• The dynamic brake is designed only for immediate stop. Configure the system to stop for about three
minutes after the dynamic brake operates.

• If an alarm occurs with the servo 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 OFF,
the Servomotor will operate according to the value set in
(Pn507).
• 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 servo 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 is always cleared to zero.
