12.8.4 Safe Speed Limit with Delay (SLS-D)
The Safe Speed Limit with Delay (SLS-D) function operates according to the Safely-
Limited Speed (SLS) function defined in IEC 61800-5-2. The deceleration operation of the
motor is monitored (deceleration monitoring) until the time set in a parameter elapses in
response to the safety request input status. The motor speed is then monitored to see if it
is within the allowable range (within range for a constant speed).
Refer to the following manual for the application procedures for the SLS-
D function.
