Commissioning Procedure for Non-Constant Power Algorithim Operation J-5
Reference Material -
The following information describes step by step processor functions for the new
commissioning procedure.
1. Calculate the necessary motor parameters and variables initially based on the
following equations: (This represents the action taken when the PMI tune function
is invoked (bit 1 of register 100/1100)).

2. Run the algorithm with the closed flux loop using the flux reference (4) directly in
the final stator flux reference point. Run the drive at the 40% speed point.
The result of this step is obtaining the first iteration of a rated magnetizing current
I
z_rtd_1
by measuring an output of a flux regulator through an averaging procedure
(at least a 1000 scan time sampling interval). Recalculate expression (2), (3), and
(5) - (9) based on new value of the flux producing current I
z_rtd_1.
3. Disable the flux loop. Set output of a flux regulator. Id_ref = √2⋅Ι

Run drive on a synchronous speed with no load condition and make a
measurement of motor voltage through an averaging procedure (at least a 1000
scan time sampling interval). This motor voltage is a rated no load motor voltage
