2.2 List of parameters
Description: Setting to change the direction of rotation.
If the parameter is changed, it reverses the direction of rotation of the motor and the encoder actual value without
changing the setpoint.
Value: 0: CW
1: CCW
Dependency: Refer to: F07434
Danger: When using external speed actual values for the speed controller (see p1440), for a direction of rotation change
(p1821 = 1), then its polarity must also be changed (e.g. for drive object ENCODER via p0410). Otherwise, a positive
coupling can occur in the speed control loop and the drive would then be accelerated up to the speed limit.
Caution: For 12-pulse converters with 30° offset angle for system 2, for a direction of rotation reversal, the phase offset
changes by 60° as the sign of the angle offset changes. This can be adapted in p1810.15.
Changing the direction using p1820 or p1821 is not recognized by the "Safe Direction without encoder". As a
consequence, the limit provided by SDI (Safe Direction) from r9733 no longer functions.
Notice: An appropriate fault is output for a drive data set changeover where the direction of rotation changes and the pulses
are enabled.
Note: For operation with the phase sequence U/V/W, the direction of rotation is defined when viewing the face side of the
motor output shaft.
When changing the direction of rotation, the rotating field direction of the current controller is reversed. The speed
actual value (e.g. r0063) is also reversed so that the control sense is kept and internally causing the direction of
rotation to be reversed with the same setpoint. Further, the position actual values of the actual encoder are reversed
(e.g. r0482[0...2]).
p1820 can be used to reverse the direction of the motor without reversing the encoder actual value.
Description: Sets the tolerance time for line phase monitoring for blocksize power units.
If a line phase fault is present for longer than this tolerance time, then a corresponding fault is output.
Dependency: Refer to: F30011
Notice: When operating with a failed line phase, depending on the active power, values higher than the default value can
either immediately damage the power unit or damage it over the long term.
Note: For the setting p1822 = maximum value, line phase monitoring is deactivated.
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.
