FUNCTION C
O
DES
P09 to P11 Motor 1 (Slip compensation gain for driving, Slip compensation response time, and
Slip compensation gain for braking)
P09 and P11 determine the slip compensation amount in % for driving and braking individually and adjust the slip amount
from internal calculation. 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.
Function codes
Operation (Slip compensation)
P09
Slip compensation gain for driving
Adjust the slip compensation amount for driving.
Slip compensation amount for driving =
Rated slip x Slip compensation gain for driving
P11
Slip compensation gain for braking
Adjust the slip compensation amount for braking.
Slip compensation amount for braking =
Rated slip x Slip compensation gain for braking
P10
Slip compensation response time
Specify the slip compensation response time. Basically, there is
no need to modify the default setting.
For details about the slip compensation control, refer to the description of F42.
P12
Motor 1 (Rated slip frequency)
P12 specifies rated slip frequency. Obtain the appropriate values from the test report of the motor or by calling the
manufacturer of the motor. Performing auto-tuning automatically sets these parameters.
• Rated slip frequency: Convert the value obtained from the motor manufacturer to Hz using the following expression and
enter the converted value. (
Note
: The motor rating given on the nameplate sometimes shows a
larger value.)
Rated slip frequency (Hz) =
(Synchronous speed - Rated speed)
×
Base frequency
Synchronous speed
For details about the slip compensation control, refer to the description of F42.
P13 to P15 Motor 1 (Iron loss factors 1 to 3)
P13 to P15 compensates the iron loss caused inside the motor under vector control with speed sensor, in order to improve the
torque control accuracy.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value. Basically,
there is no need to modify the setting.
P16 to P20
P21 to P23
Motor 1 (Magnetic saturation factors 1 to 5)
Motor 1 (Magnetic saturation extension factors "a" to "c")
These function codes specify the characteristics of the exciting current to generate magnetic flux inside the motor and the
characteristics of the magnetic flux generated.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Performing auto-tuning while the motor is rotating (P04 = 2 or 3) specifies these factors automatically.
