Safety instructions Overview This chapter states the general safety instructions that must be followed when installing and operating drives with sine filters. The material in this chapter must be studied before attempting any work on the filters. In addition to the safety instructions given below, read the complete safety instructions of the specific drive (presented in the Hardware Manual accompanying the drive) you are working on.
Intended audience The manual is intended for the people who are responsible for installing, commissioning and using sine filters with ACS800 drives. The reader is expected to have a basic knowledge of electrical fundamentals, electrical wiring practices, the drive, and the use of the drive control panel.
General Sine filters are low-pass filters that suppress the high frequency components of the drive output. The sine filters available for the ACS800 consist of single- or three- phase reactors and delta- or star-connected capacitors. The following diagram shows a drive system with a sine filter.

Appendix – Step-up applications What this chapter contains This chapter contains additional information on step-up applications. All parameter numbers refer to the ACS800 Standard Application Program (version ASXR7210 or later). Principle of a step-up drive system The main idea of a step-up application is that it enables the use of a medium-voltage motor with a low-voltage drive.
Cable type Cable between drive and transformer primary The cabling between the drive and the step-up transformer is the normal motor cable type. Recommendations are given in the Hardware Manual of the drive. Cable between transformer secondary and motor The cable is to be chosen according to the application. Unshielded cable can be used.
Transformer dimensioning Transformer selection is based on the demands of the application. DC components together with the demands for starting torque form the need for voltage boost. A special transformer must be used when the required starting torque is over 50% of nominal torque, or if the motor cable length is over 300 metres (984 ft).
Secondary side The following diagram represents the secondary side of a step-up system. / sqrt(3) / sqrt(3) The impedance of the secondary side equals The system is dimensioned using the nominal current of the motor: Thus, the minimum voltage for the transformer secondary equals ⋅...
Example The nominal voltage of the drive in this calculation is 690 V. Motor 3300 V 106 A 50 Hz ϕ 0,82 3300 ------------------- - Ω 17.97 Ω ≈ ⋅ ⇒ 17,97 0,82 Ω 14,74 Ω ⋅ ≈ ⋅ Ω 10,29 Ω ≈...
Transformer specification sheet The table below lists items to be submitted to the manufacturer of the transformer. Parameter Specification 1. Quantity and type of transformers 2. Rated power, primary S (kVA) 3. Rated power, secondary S (kVA) 4. Rated voltage, primary U 5.
Parameter settings before use The following drive parameter settings should be made before starting up a step-up drive system. 95.04 EX/SIN REQUEST Set the parameter to SIN or EX&SIN. For more information, see the Firmware Manual of the drive. 26.03 IR COMPENSATION 26.04 IR STEP-UP FREQ Voltage boosting is used in step-up applications to achieve a higher starting torque.

Without IR compensation, the motor can only give a very low starting torque at its nominal current. A typical relation between the starting torque and current is shown below. T / T rated I / I rated The current depends on the demand for starting torque. The magnetizing current of the motor equals ϕ...
At frequency f, the normally required voltage equals ⋅ --- - U input Thus, the required boost equals drop,primary ⋅ --------------------------------------------- - 100% BOOST The transformer is dimensioned according to the specified voltage boost. Example In this example, the voltage boost (BOOST) is calculated for a 50% torque. The motor data etc.
Page 42
In practice, the voltage boost is achieved through IR compensation. In the example, the parameter 26.03 IR COMPENSATION should be set to 6% (0.06 × 690 V = 41.4 V). IR compensation should start at approximately slip frequency in order to avoid transformer saturation. This can be achieved using parameter 26.04 IR STEP-UP FREQ.
