AC100 HIGH-PERFORMANCE VC INVERTER MANUAL
Low-frequency current
F6.47
increasing extent
Low-frequency current
F6.48
increasing end frequency
Permanent magnet motor VC without PG (F0.00 = 6), adjust [F6.47] to improve the motor starting torque and low-load
capacity, but it will increase low-operating current.
F6.49 Low-frequency current D-axis gain
F6.50 Low-frequency current Q-axis gain
Permanent magnet motor VC without PG (F0.00 = 6) current control parameters; if there's abnormal vibration when the
motor start with low frequency, the current gain can be reduced; if there is not enough torque, gain can be increased to
improve start torque.
F6.51 Magnetic flow setting intensity
Magnetic flow control proportional
F6.52
gain
F6.53 Magnetic flow control integral gain
Permanent magnet motor VC without PG (F0.00 = 6) current limit parameters, [F6.51] set the motor excitation intensity;
adjusting the motor magnetic field strength can optimize and reduce the motor current under same load; if there is an
output voltage instability or motor speed instability, it can be adjusted and improved by [F6.53] and [F6.53].
F6.54 Over-current suppression point
F6.55 Over-current suppression gain
F6.56 Over-current suppression integral
Permanent magnet motor VC without PG (F0.00 = 6) current limit parameters; when current increases to the upper limit
of [F6.54], when the load increases, the current increases; if current increases to the upper limit of [F6.54], the drive
automatically reduces the output frequency to reduce the power and make sure the control current does not exceed the
upper limit; [F6.55] and [F6.57] are the current controller parameters, if there's over current and frequency decreasing
instability, adjustment can be made to improve.
F6.57 DC pull-in time
Permanent magnet motor VC without PG (F0.00 = 6), if there is start failure or start instability, the parameter may be
appropriately increased to solve the startup instability.
