Note: When the maximum speed is changed, the pulse frequency P1800 is automatically limited to this minimum ratio. It
is not permissible to reduce the pulse frequency if this would result in this ratio being fallen below.
p1825 Converter valve threshold voltage / Threshold voltage
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Modulation
Min
0.0 [Veff]
Description: Sets the threshold voltage drop of the valves (power semiconductor devices) to be compensated.
Note: The value is automatically calculated in the motor data identification routine.
p1828 Compensation valve lockout time phase U / Comp t_interl ph U
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Modulation
Min
0.00 [µs]
Description: Sets the valve lockout time to compensate for phase U.
Note: The value is automatically calculated in the motor data identification routine.
p1829 Compensation valve lockout time phase V / Comp t_interl ph V
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Modulation
Min
0.00 [µs]
Description: Sets the valve lockout time to compensate for phase V.
p1830 Compensation valve lockout time phase W / Comp t_interl ph W
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Modulation
Min
0.00 [µs]
Description: Sets the valve lockout time to compensate for phase W.
p1832 Deadtime compensation current level / t_dead_comp I_lev
VECTOR Can be changed: U, T
Data type: Floating Point
P-Group: Modulation
Min
0.0 [Aeff]
Description: Above the current level, the deadtime - resulting from the converter switching delays - is compensated by a previ-
ously calculated, constant value . If the relevant phase current setpoint falls below the absolute value defined by
p1832, the correction value for this phase is continuously reduced.
Dependency: The factor setting of p1832 is automatically set to 0.02 * rated drive converter current (r0207).
If the actual operating frequency exceeds the value of p1831, then p1832 is not applied!
