5.3 Description of Function Codes 5.3.4 P codes (Motor 1 parameters)
Synchronous motor 1 (NS discrimination current command value)
Refer to P30.
These function codes are displayed, but they are reserved for particular manufacturers. Unless otherwise specified,
do not access these function codes.
Motor 1 (Synchronous motor control switching level)
These are the control parameter for PMSMs. Normally, it is not necessary to change the data of these function
codes.
Motor 1 (Synchronous motor overcurrent protection level)
Sets the synchronous motor demagnetization limit current value with an effective value. Check the demagnetization
limit current value with the motor manufacturer.
Synchronous motors have 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 0C1, 0C2 or 0C3.
Motor 1 (Synchronous motor magnetic pole position sensor offset)
Adjusts the offset with the actual magnetic pole position for PM motors with magnetic pole position sensor, and
detection position with magnetic pole position sensor. If using a Fuji standard synchronous motor (GNF2 series),
set the magnetic pole position offset value indicated on the product tag.
This can be adjusted automatically by auto tuning.
