Section 1 General Information Electrical Noise Considerations All electronic devices are vulnerable to significant electronic interference signals (commonly called “Electrical Noise”). At the lowest level, noise can cause intermittent operating errors or faults. From a circuit standpoint, 5 or 10 millivolts of noise may cause detrimental operation. For example, analog speed and torque inputs are often scaled at 5 to 10 VDC maximum with a typical resolution of one part in 1,000.
Section 1 General Information Electrical Noise Considerations Special Drive Situations Continued For severe noise situations, it may be necessary to reduce transient voltages in the wires to the motor by adding load reactors. Load reactors are installed between the control and motor. Reactors are typically 3% reactance and are designed for the frequencies encountered in PWM drives.
Section 6 Manual Tuning the Series 22H Control Manually Tuning the Control In some applications the drive cannot be accurately auto-tuned in an application. In these cases it is necessary to calculate the values needed to tune the drive and manually enter these calculated parameter values. Motor Mag Amps Parameter This parameter is located in the Level 2, Motor Data Block. This parameter is normally entered using the nameplate data (motor no load amps) or auto−tuned.
Section 1 General Information Current Int Gain Parameter The Current Int Gain parameter located in the Level 1 Vector Control Block is factory preset at 150 Hz. This setting is suitable for essentially all systems. DO NOT CHANGE WITHOUT FACTORY APPROVAL. Speed Prop Gain Parameter The Speed Prop Gain parameter located in the Level 1 Vector Control Block is factory set to 10. This gain may be increased or decreased to suit the application.
Section 1 General Information PI Controller Both the current and rate control loops are of the Proportional plus Integral type. If “E” is defined to be the error signal, E = Command − Feedback then the PI controller operated on “E” as Output = (Kp * E) + (Ki s E dt) where Kp is the proportional gain of the system and Ki is the integral gain of the system. The transfer function (output /E) of the controller using 1/s (Laplace Operator) to denote the integral, Output/E = Kp + KI / s = Kp (s + Ki/Kp) /s.
