5.3 Soft Limit & JOG & Quick Stop
5.3.1 Soft Limit
The soft limit function means that the internal position feedback of the drive is compared with the limit position, an alarm and
stop when determining that the motor exceeds the limit position. Soft limit function is universal for linear movement and
rotating movement.It is not requiring hardware, eliminating malfunction due to poor wiring contact, and it can prevent
mechanical slip and abnormal action with internal position comparison. And the EM2RS series drives carry out homing to find
the mechanical home before the soft limit function can be activated.
