Stop methods
■
Classification of stop methods
The stop method of the servo motor is determined by the parameter settings or the factor that activated the SS1 function. The
following table lists the stop methods for the servo motor when the SS1 function is activated.
*1 There are three stop methods: DB, EDB, and SD.
DB: Dynamic brake stop (for a servo amplifier without the dynamic brake, the servo motor coasts)
EDB: Stop with electronic dynamic brake
SD: Forced stop deceleration
*2 The stop method differs depending on the alarm stop method. For the stop method of each alarm, refer to Chapter 6.
*3 For specific servo motors, refer to "[Pr. PF06.0 Electronic dynamic brake selection]" in the following manual.
MR-J5-G/MR-J5W-G User's Manual (Parameters)
*4 The stop method in continuous operation to torque control mode is the same as that in the torque control mode.
