Safety Function
4.5.4 SLS function
■How SLS function works
The SLS function can monitors that the motor speed does
not exceed the determined speed safely during the inverter
outputs to the motor.
The SLS function can be used by inputting SLS-A or SLS-B
function individually.
When SLS-A and SLS-B are activated at the same time, SLS-
A is higher priority function.
Releasing of SLS function depends on the activation of SLS
signal input.
The speed upper limit in the SLS state is determined by
speed limit [oC-14]/[oC-24] or [oC-15]/[oC-25] in the
setting parameters of SJ-P1. Deceleration time in the SLS
starting state is determined by Deceleration time [oC-12]
or [oC-22] in the setting parameters of SJ-P1.
