Determining the
field angle without
motor motion
A distinction must be made if you intend to determine the field angle without
motor motion (MP_motFieldAdjustfMove = mode 0):
Commissioning: No field angle has been determined yet
(MP_motPhiRef =0)
A field angle has already been determined (MP_motPhiRef ≠ 0).
The field angle is determined automatically after switching on the drive. This
process lasts approximately 4 to 6 seconds (the PLC program must not
rescind the drive enabling during this time).
If the power module is not active before the determination of the field angle
begins, the error message 8B40 No drive release <axis> appears. If the
power module switches off during the determination, 8B50 Axis module
<axis> not ready appears.
Field angle not yet determined (MP_motPhiRef = 0):
If the field angle on this machine was not yet determined after the control was
started (MP_motPhiRef = 0), the determination starts automatically. The
method used to determine the field angle is set in
MP_motTypeOfFieldAdjust. The determined field angle is stored in
MP_motPhiRef.
Field angle already determined (MP_motPhiRef ≠ 0):
If the field angle on this machine was already determined after the control was
started (MP_motPhiRef ≠ 0), a distinction must be made:
If an absolute encoder with EnDat interface is being used:
The absolute position of the encoder is read immediately after the control
has been started. The field angle from MP_motPhiRef is assigned to this
position. Therefore, the first motor motion already occurs with the
determined field angle.
If an incremental encoder is being used:
Immediately after the control has been started and the control voltage has
been switched on, then depending on MP_motTypeOfFieldAdjust a field
angle is determined with which the motor can be traversed over the
reference mark. After traversing the reference mark, the field angle from
MP_motPhiRef is assigned. The subsequent motor motions utilize the field
angle from MP_motPhiRef.
Initial operation, field angle has not been determined yet
(MP_motPhiRef = 0): Determination of the field angle is started
automatically when the MANUALplus 620 is switched on. The method for
determining the field angle is set in MP_motTypeOfFieldAdjust. The
determined angle is stored in MP_motPhiRef.
