Autophasing modes
Several autophasing modes can be set with parameter
IDRUN MODE:
• For Turning mode without the load connected – select Autophs turn
• For Turning mode with the load connected – select Autophs rope
• For Static modes 1 and 2 perform pulse test with a closed brake – select
Autophs st1/ Autophs st2.
Turning mode
– is the most robust and accurate method. In this mode, the motor
shaft can be turned back and forward (±360/polepairs)° to determine the rotor
position. The ropes must be removed from the traction sheave for load free
movement.
Turning mode with ropes on
– can be used if the lift cabin is allowed to move few
tens of centimeters up. This method uses the natural unbalance of the lift when the
cabin is empty. During the autophasing procedure, the cabin moves few tens of
centimeters upward and during this movement drive detects the angle offset. The
cabins moves very slowly due to the drive braking feature.
Static modes
– can be used if the motor cannot be turned when the load is
connected. As the characteristics of different motors differ, test and select the suitable
mode.
Encoder angle offset write to 0
– The autophasing offset angle can be used to set
the zero position of encoder. When the autophasing offset angle is measured, it can
be written to the encoder memory as zero position with parameter
OFFSET SRC = Set zero pos. Also select parameter
ENC PAR REFRESH to
trigger the written value to encoder. After this configuration, the drive can use a zero
offset angle.
Settings
Parameters
Additional information
ENC PAR REFRESH
Forces a reconfiguration of the FEN-xx interfaces, which is needed for
any parameter changes in groups 90…93 to take effect.
USE GIVEN PARAMS
Activates the motor model parameters
and the rotor angle
POS OFFSET USER
Defines an angle offset between the zero position of the synchronous
motor and the zero position of the position sensor.
IDRUN MODE
Selects the type of the motor identification performed at the next start of
the drive in the DTC mode to identify the motor characteristics for
optimum motor control.
POS OFFSET SRC
Select the source for the angle offset between the zero position of the
synchronous motor and the zero position of the position sensor.
