4.5.2 SS1 function
■How SS1 function works
The SS1 function can decelerates the motor speed to stop
by monitoring the time or speed until the motor speed to
stop. Eventually, SS1 function transits to STO function.
The SS1 function can be used by inputting SS1-A or SS1-B
function individually.
When SS1-A and SS1-B are activated at the same time,
SS1-A is higher priority function.
The setting [1-12]STO-A release mode / [2-12]STO-B
release mode is applied after transition to STO function.
Releasing of SS1 function depends on the activation of SS1
signal input.
Deceleration time in the SS1 state is determined by
Deceleration time [oC-10] or [oC-20] in the setting
parameters of SJ-P1.
