Parameters Details
 Select the stopping method at an alarm.
 Refer to the Emergency Stop Operation at Alarms in "11-3 Alarms (P.11-6)".
 The dynamic brake is rated for short-term operation. Use it only for emergency stopping. Design
the system to stop for at least three minutes after the dynamic brake operates. Otherwise, the
dynamic brake circuits may fail or the dynamic brake resistor may burn.
Explanation of Set Values
*1. Decelerating refers to a period between when the motor is running and when the motor speed reaches
30 r/min or less. Once the motor reaches a speed of 30 r/min or less and moves to the after stop
status, follow the subsequent operation based on the after stop status regardless of the motor speed.
*2. The motor may make a sudden motion.
*3. The Operation A and Operation B indicate whether to have an
emergency stop at an error. An
emergency stop takes place by the Operation A, when an emergency stop alarm occurs. It is the
normal stop by Operation B, when the alarm occurred does not support the
emergency stop.
 Set the torque limit for emergency stops.
 Set the torque limit for the following cases.
•
Drive prohibition deceleration with the Stop Selection for Drive Prohibition Input (Pn505) set to 2.
• Deceleration with the Stop Selection with Main Power Supply OFF (Pn507) set to 8 or 9.
• Deceleration with the Stop Selection with Servo OFF (Pn506) set to 8 or 9.
 The normal torque limit is applied if this parameter is set to 0.
 Set the value in units of 1% of the rated torque (100%).
