p4826

Function generator offset / FG offset

CU_DC, CU_DC_R, Can be changed: U, T
CU_DC_R_S,
Data type: FloatingPoint32
CU_DC_S
P-Group: Trace and function generator
Not for motor type: -
Min
-1600.00 [%]
Description: Sets the offset (DC component) of the signal to be generated for the function generator.
Dependency: Units are dependent on p4810.
If p4810 = 1, 2, 4: The offset is referred to p2002 (reference current).
If p4810 = 3, 5: The offset is referred to p2000 (reference speed).
If p4810 = 2: In order to avoid the undesirable effects of play (backlash), the offset does not act on the current
setpoint, but instead on the speed setpoint.
p4827

Function generator ramp-up time to offset / FG ramp-up offset

CU_DC, CU_DC_R, Can be changed: U, T
CU_DC_R_S,
Data type: FloatingPoint32
CU_DC_S
P-Group: Trace and function generator
Not for motor type: -
Min
0.00 [ms]
Description: Sets the ramp-up time to the offset for the function generator.
p4828

Function generator lower limit / FG lower limit

CU_DC, CU_DC_R, Can be changed: U, T
CU_DC_R_S,
Data type: FloatingPoint32
CU_DC_S
P-Group: Trace and function generator
Not for motor type: -
Min
-10000.00 [%]
Description: Sets the lower limit for the function generator.
Dependency: For p4810 = 2 the limit only applies to the current setpoint, but not the speed setpoint (offset).
p4829

Function generator upper limit / FG upper limit

CU_DC, CU_DC_R, Can be changed: U, T
CU_DC_R_S,
Data type: FloatingPoint32
CU_DC_S
P-Group: Trace and function generator
Not for motor type: -
Min
0.00 [%]
Description: Sets the upper limit for the function generator.
Dependency: For p4810 = 2 the limit only applies to the current setpoint, but not the speed setpoint (offset).
p4830 Function generator time slice cycle / FG time slice
CU_DC, CU_DC_R, Can be changed: U, T
CU_DC_R_S,
Data type: FloatingPoint32
CU_DC_S
P-Group: Trace and function generator
Not for motor type: -
Min
0.03125 [ms]
Description: Sets the time slice cycle in which the function generator is called.
