PMSM Motor 1 (d-axis inductance magnetic saturation correction, Flux limitation value)
These are the control parameter for PMSMs. Normally, it is not necessary to change the data of these function
codes.
P74
PMSM Motor 1 (Reserved)
These function codes are displayed, but they are reserved for particular manufacturers. Unless otherwise specified,
do not access these function codes.
P90
PMSM Motor 1 (Overcurrent protection level)
A PMSM has a current limit to prevent demagnetization of permanent magnet. If a current exceeding that limit
flows through the motor, it weakens the magnet force of permanent magnet so that the motor does not get the
desired characteristics.
To prevent it, P90 specifies the overcurrent protection level. If a current flows exceeding the level, the inverter
causes an overcurrent protection alarm

P99
Motor 1 selection
P99 specifies the motor type to be used.
P99 data Function
0 Motor characteristics 0 (Fuji standard IM, 8-series)
1 Motor characteristics 1 (HP rating IMs)
4 Other IMs
20 Other PMSMs
21 Motor characteristics PM (Fuji standard PMSM, GNB-series)
To select the motor drive control or to run the inverter with the integrated automatic control functions such as auto
torque boost and torque calculation monitoring, it is necessary to specify the motor parameters correctly.
First select the motor type with P99 from Fuji standard motors 8-series, set P02 (capacity) and then initialize the
motor parameters with H03. This process automatically configures the related motor parameters (P01, P03, P06
through P13,P53 and H46).
The data of F09 (Torque boost 1), H13 (Restart mode after momentary power failure (Restart time)), and F11
(Electronic thermal overload protection for motor 1 (Overload detection level)) depends on the motor capacity, but
the process stated above does not change them. Specify and adjust the data during a test run if needed.
