5.3 Description of Function Codes
5-234
d24 Zero speed control (Refer to F23)
Refer to the description of F23.
d25 ASR switching time (Refer to d01)
Refer to the description of d01.
d32, d33 Speed limits / Over speed level 1 and 2 (Refer to H18)
Under speed control, the over speed detection levels are specified with 120% of these function codes.
The other hand, these function codes specifies the speed limit value under torque control.
Refer to the description of H18.
d35 Over speed detection level (Refer to H18)
Refer to the description of H18.
d41 Application specific function selection
d41 selects/deselects line speed control or master-follower operation (immediate synchronization mode at the start
or follow-up mode during acceleration).
Line speed control suppresses an increase in line speed resulting from the increasing radius of the take-up roll in a
winder system.
Master-follower operation drives two or more shafts of a conveyer while keeping their positions in synchronization.

Data for d41 Function
0 Invalid
1 Line speed control with speed sensor
Note: This control is valid only when “V/f control with speed sensor” or “Vector control with
speed sensor (with auto torque boost)” is selected with F42, A14, b14, or r14 (data = 3
or 4).
2 Master-follower operation(Immediate synchronization mode at the start, without Z phase)
3 Master-follower operation(Follow-up mode during acceleration)
4 Master-follower operation(Immediate synchronization mode at the start, with Z phase)
