n7-11: Pull-in Current Switch Hysteresis Band
No.

(Hex.)
n7-11 Pull-in Current Switch
Hysteresis Band
(311B)
Expert
Note:
• The value set in n8-51 [Pull-in Current @ Acceleration] is enabled for speeds that are not higher than n7-10 + n7-11 during acceleration.
The value set in b8-01 [Energy Saving Control Selection] is enabled for speeds higher than n7-10 + n7-11.
• If there is a large quantity of oscillation when you operate in the low speed range, increase the setting value.
• When it is most important to save energy in the low speed range, decrease the setting value.

TemperatureCorrection
(3122)
0 : Invalid
1 : Valid (Only 1 time)
2 : Valid (Every time)
Note:
• For settings 1 and 2, the adjustment time can cause a delay before startup.
• For settings 1 and 2, the drive can set the line-to-line resistance value of E9-10 [Motor Line-to-Line Resistance].
• When the temperature will change at startup, use setting 2.
• To decrease the startup time, set this parameter to 0, then do line-to-line resistance tuning.
• If you will start from coasting, set this parameter to 0, then do line-to-line resistance tuning.

n8: PM Motor Control Tuning

n8 parameters are used to make adjustments when controlling PM motors.

n8-01: Pole Position Detection Current
No.
Name
(Hex.)
n8-01 Pole Position Detection
Current
(0540)
The drive uses the Initial Rotor Position Estimated Current to detect the initial position of rotors.
Use the "Si" value on the motor nameplate, if available.
Note:
When A1-02 = 7 [CLV/PM], this parameter takes effect only in Expert Mode.
YASKAWA TOEPYAIGA8002B GA800 Drive Programming
V/f CL-V/f OLV CLV AOLV
Sets the hysteresis level for Switching Speed set in n7-10 [Pull-in Current Switching Speed]. When
the speed is lower than n7-10 + n7-11 during acceleration, the drive enables pull-in current.
V/f CL-V/f OLV CLV AOLV
Sets a time to enable the pull-in current commands.
V/f CL-V/f OLV CLV AOLV
Sets the function to adjust for changes in the motor resistance value caused by changes in the
temperature.
V/f CL-V/f OLV CLV AOLV
Sets, as a percentage, the Initial Rotor Position Estimated Current, taking the E5-03 [Motor Rated
Current (FLA)] as the 100% value. Usually it is not necessary to change this setting.
