Chap. 9 FUNCTION CODES
P09
Motor 1 (Slip compensation gain for driving)
A23 (Motor 2, Slip compensation gain for driving)
P10
Motor 1 (Slip compensation response time)
A24 (Motor 2, Slip compensation response time)
P11
Motor 1 (Slip compensation gain for braking)
A25 (Motor 2, Slip compensation gain for braking)
P09 and P11 determine the slip compensation amount in % for driving and braking,
respectively. Specification of 100% fully compensates for the rated slip of the motor.
Excessive compensation (P09, P11 > 100%) may cause hunting (undesirable oscillation of
the system), so carefully check the operation on the actual machine.
P10 determines the response time for slip compensation. Basically, there is no need to modify
the default setting. If you need to modify it, consult your Fuji Electric representatives.
P12
Motor 1 (Rated slip frequency) P06 (Motor 1, No-load current)
P07 (Motor 1, %R1)
P08 (Motor 1, %X)
A26 (Motor 2, Rated slip frequency)
For details about setting of the rated slip frequency of motor 1, refer to the descriptions of P06
to P08.
P99 Motor 1 Selection A39 (Motor 2 Selection)
P99 specifies the type of motor 1 to be used.
Data for P99 Motor type
0 Motor characteristics 0 (Fuji standard IM, 8-series)
1 Motor characteristics 1 (HP rating IM. Typical in North America)
3 Motor characteristics 3 (Fuji standard IM, 6-series)
4 Other motors (IM)
20 Other motors (PMSM)
21 Fuji standard PMSM without sensor (GNB series)
Automatic control (such as auto torque boost and auto energy saving) or electronic thermal
overload protection for motor uses the motor parameters and characteristics. To match the
property of a control system with that of the motor, select characteristics of the motor and set
H03 data (Data Initialization) to "2" to initialize the motor parameters stored in the inverter.
The initialization automatically updates the P03 and P06 to P12 data and the constants used
inside the inverter.
According to the motor model, set the P99 data as shown below.
- For Fuji standard IM, 8-series (Current standard induction motors), P99 = 0
- For Fuji standard IM, 6-series (Conventional standard induction motors), P99 = 3
- For other manufacturers' IM or model-unknown IM, P99 =4
- For PMSM, P99 = 20 or 21 (to be selected after consultation with motor manufacturers)
• When P99 = 4, the inverter runs following the motor characteristics of Fuji
standard IM, 8-series.
• When P99 = 1, the inverter applies to the characteristics of HP rating IM (Typical
in North America).
