Tuning
These parameters help tune the motor for your application, which include Torque Compensation and
S-Curve characteristics for smoother transition during machine acceleration and deceleration. Below
are the parameters included in this section.
•
D1 DC Injection
•
D2 Automatic Slip Compensation
•
D3 Torque Compensation
•
D8 Dwell Function
•
D9 S-Curve Acceleration/Deceleration
•
D10 Carrier Frequency
•
D11 Hunting Prevention
DC Injection
DC Injection can be used to stop a motor whose rotational direction is uncertain at start-up.
With Decel to Stop enabled (B03.03 = 00), upon removal of the run command the IMPULSE•G+
Mini drive controls motor deceleration according to the Decel Time setting, until output frequency
reaches the DC Injection Braking Start Frequency (D01.01 setting). Then the drive output is turned
off and DC injection current is applied to the motor. The effective DC injection time and current
should be set to provide adequate stopping without excessive motor heating. The DC injection
voltage is determined by the DC injection braking current and motor impedance.
