Parameter Name
resolver active resol
The actual resolution setting for the speed / position feedback.
The resolution setting affects the dynamic performance of the feedback.
In 'AUTO' mode, the actual resolution in use may be different from the target resolution, depending on other parameter settings :
12 BITS
only use for excitation between 6kHz and 20kHz.
14 BITS
only use for excitation between 3kHz and 12kHz, and max. speed parameter set < 30000rpm.
Max speed* set up < 30000RPM
16 BITS
only use for excitation between 2kHz and 10kHz, and max. speed parameter set < 7500rpm.
Max speed* set up < 7500RPM
(*) : if the option is the active feedback, then Max speed = 464 100% Speed in RPM
If the opion is not the active feedback, then Max speed = 1825 Resolver Max Speed
Resolver State
The state of the Resolver Feedback Option.
ACTIVE = Operating
TRIPPED = Not-Operating due to a detected fault (see parameter Resolver Trip Type).
1 A fault detected when the option is being used as the active feedback will cause a drive trip, stopping the motor.
Resolver Turns Reset
Used to reset both the Resolver Turns and Fraction Turns to zero, and Resolver Trip Type.
The turns count parameters are held at zero whilst this parameter is held TRUE.
The state of this parameter does not affect the operation of the resolver as a speed / position feedback, it only affects the turn count diagnostics.
Resolver Reset Power On
When TRUE the Resolver Turns and Resolver Fraction Turns parameters are reset to zero on drive power-on.
When FALSE the Resolver Turns and Resolver Fraction Turns parameters will persist through power cycling. The absolute shaft position with be
retained, provided that no more than 180° of resolver coil rotation has occurred during the power-off state.
