BILEVEL DRIVE The basic function of a step motor driver is to control the motor winding currents Motor performance is determined by how fast the driver can increase and decrease the winding currents A rapid rise in winding current is achieved by applying a high voltage directly to a motor This rapid rise of current is also referred to as the kick or operating current When a desired current level is reached a low voltage is applied to maintain a suitable holding current level When a motor winding is turned off a rapid decrease in winding current is achieved by routing the energy in the collapsing field back to the power supply through a high voltage path The high voltage supply furnishes the energy necessary to maintain motor output torque at high step rates thus providing high mechanical power output The low voltage supply provides much of the current needed at low step rates and all of the holding current Bilevel drivers do not use high frequency switching techniques as chopper drivers do Consequently they do not create the EMI RFI and motor heating problems that are associated with chopper drivers www nok eroup cn TRANSIENT VOLTAGE SUPPRESSION Transient Voltage Suppression TVS Diodes on the motor phase outputs allow for much longer motor cables to be used Normally when using long motor cables voltage transients and spikes are created These transients often exceed the voltage ratings of the output
