12 Appx. 3: Protection Function
Sets the safely limited speed of the machine and motor for which the SLS (Safely Limited Speed) function is
executed.
【#2233】 SV033 SSF2 Servo function 2
bit D : rps Safely limited speed setting increment
Change the setting units of the specified speed signal output speed (SV073) and safely limited
speed (SV238).
0: mm/min
【#2438】 SV238 SSCFEED Safely limited speed
Set the machine's safely limited speed for the SLS (Safely Limited Speed) function.
Set this parameter within the following setting ranges.
For linear axis: 2000mm/min or less
For rotary axis: 18000°/min (50r/min) or less
When not using, set to "0".
---Setting range---
【#2439】 SV239 SSCRPM Safely limited motor speed
Set the motor's safely limited speed for the SLS (Safely Limited Speed) function.
Set a value to hold the following relationship.
Be aware when setting the parameter as the setting units for general motors and linear motors are
different.
<<For general motor>>
SV239=(SV238/SV018) × (SV002/SV001)
Only when the product is 0, set to "1".
<<For linear motor>>
SV239=SV238/60
Only when the product is 0, set to "1".
---Setting range---
(Note) The value of the safely limited speed and safely limited motor speed must satisfy the above relation.
If this relation is not satisfied, the parameter error (37or E4) will occur.(Error parameter No. is 239.)
Checking this relation is executed when the drive unit is turned ON and parameter is changed and speed
observation mode (states when a speed observation command is turned ON) is entered.

Note that "1 (r/min)" is applied when the calculation result is "0 (r/min)"

1: 100mm/min
0 to 18000 (mm/min) or (°/min)
However, when SV033/bitD=1, the setting range is from -32768 to 32767 (100 mm/min) or
(100°/min).
When not using, set to "0".
For general motor:0 to 32767 (r/min)
For linear motor: 0 to 32767 (mm/s)
