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.
Description: Sets the valve lockout time to compensate for phase U.
Note: The value is automatically calculated in the motor data identification routine.
Description: Sets the valve lockout time to compensate for phase V.
Description: Sets the valve lockout time to compensate for phase W.
Description: Sets the current level for the dead time compensation.
Above the current level, the dead time - resulting from the converter switching delays - is compensated by a
previously calculated constant value. If the relevant phase current setpoint falls below the absolute value defined by
p1832, the corrective value for this phase is continuously reduced.
Dependency: The factory setting of p1832 is automatically set to 0.02 * rated drive converter current (r0207).
