363-SCJ - Moment of inertia of system
Source: Speed Controller Inertia
Function: Moment of inertia of the system, reduced onto the motor shaft
384-SCSMX - Speed limitation of speed controller
Source: Speed Controller Speed Maximum
Function: With this parameter the rotation speed of the motor can be limited where necessary specific
to application (also with torque control).
1) ≤ MOSMX with asynchronous motors; ≤ MOSNM with synchronous motors
376-SCTF - Time constant of speed reference filter
Source: Speed Controller Time Filter
Function: The speed reference filter damps the control in case of speed reference step-changes.
Values:
Minimum Maximum Factory set. Unit MODE SMARTCARD Type
0 1000 0 kgmm R1W3 APPLI FLOAT32
Values:
Minimum Maximum Factory set. Unit MODE SMARTCARD Type
0 (12000) 1) 3000 rpm R1W3 APPLI FLOAT32
Note:
The highest possible speed is dependent on the motor used (MOSMX for asynchro-
nous machines, MOSNM for synchronous machines).
Notes on use of the PosMod positioning and sequence control:
l Asynchronous machines can only be run up to the motor nominal speed
MOSNM!
l To limit the positioning speed use machine parameter K14 (not SCSMX).
Values:
Minimum Maximum Factory set. Unit MODE SMARTCARD Type
0 1 0 s R5W5 DRIVE FLOAT32
Note:
SCTF is correctly preset for all operation modes. In "electronic gearing" mode SCTF
is shut off, for example, because the dead times would have a disturbing effect as a
result of the filter.
