YASKAWA TOEPYAIGA5001A GA500 DRIVE MAINTENANCE & TROUBLESHOOTING
Sets the speed range to operate with the pull-in current command. Drive rated frequency = 100%
value. If there is a large quantity of oscillation when you operate in the low speed range, increase the
setting value.
Sets the function to adjust for changes in the motor resistance value caused by changes in the
temperature.
0 : Invalid
1 : Valid (Only 1 time)
2 : Valid (Every time)
Sets the gain for magnetic flux compensation. Usually it is not necessary to change this setting.
Sets the Initial Rotor Position Estimated Current as a percentage where E5-03 [PM Motor Rated
Current (FLA)] = 100%. Usually it is not necessary to change this setting.
Sets the current at the time of polar attraction as a percentage where E5-03 [motor rated current] is
100%. Usually it is not necessary to change this setting.
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
Sets the gain for speed estimation. Usually it is not necessary to change this setting.
Sets the proportional gain for current regulator q-axis control when the drive estimates the initial
pole. Usually it is not necessary to change this setting.
Sets the integral time for current regulator q-axis control when the drive estimates the initial pole.
Usually it is not necessary to change this setting.
Sets the q-axis limit of the current regulator when the drive estimates the initial pole. Usually it is not
necessary to change this setting.
Sets the proportional gain for current regulator d-axis control when the drive estimates the initial
pole. Usually it is not necessary to change this setting.
Sets the integral time for current regulator d-axis control when the drive estimates the initial pole.
Usually it is not necessary to change this setting.
Sets the d-axis limit of the current regulator when the drive estimates the initial pole. Usually it is not
necessary to change this setting.
Sets how the drive detects the position of the rotor when the motor starts.
Note:
• When you use an SPM motor, set n8-35 = 0. When you use an IPM motor, set n8-35 = 0 to 2.
• When you set n8-35 = 1, do High Frequency Injection Auto-Tuning.
