5.3 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
•
D9 S-Curve Acceleration/Deceleration
•
D10 Carrier Frequency
•
D11 Hunting Prevention
5.3.1 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

motor deceleration according to the Decel Time setting, until output frequency reaches the DC Injection Braking
Start Frequency (D01.01 setting). Then the VFD 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.
