1. The MOTOR ON OFF input can be used to turn off all four motor phases de energize the motor in applications where motor detent torque is sufficient to maintain the load position This feature can be used to reduce the load on the power supply and the heat dissipation in the driver circuitry and L010034a motor Terminal 10 is the MOTOR ON OFF Input ADJUSTING THE KICK CURRENT The kick or operating current level is the desired phase current level that the high voltage provides each time a step is taken The high voltage is turned off when this level is reached The kick current level should be set to approximately 1 4 times the rated phase current For example a motor rated at 10 amps phase should be kicked to 14 amps Table 2 shows various kick current levels for corresponding phase currents When using a motor listed in Table 3 use the recommended potentiometer setting WARNING The kick current level must be set before operating a motor MOTOR DRIVER CONNECTIONS Motor wires are connected to the driver pack through terminals 1 2 3 12 13 and 14 Electrical connections to control inputs should be kept physically EXTERNAL X DON T CARE separated from the motor connections Wiring from the driver to the motor should be routed away from all other wiring Hookup diagrams are shown in Figures 2 3 CONNECTOR P1 This 14 pin header type connector is used for a direct connection from the DPFHPO001 to Ana2. CLOCK input Similarly when a logic 0 is applied the motor will step in the counterclockwise direction when pulses are applied to the CLOCK input When programmed as CCW input the motor will step in the counterclockwise direction when pulses are applied to this input pulse requirement is same as for CLOCK input MODE SELECT 5VDC OUTPUT Terminal 9 When programmed as Mode Select Input set by JP2 this terminal is internally pulled up to 5VDC through a 10k ohm resistor When a logic 1 or no connection is applied the motor will operate in halfstep mode When a logic 0 is applied the motor will operate in fullstep mode When this terminal is programmed as 5VDC Output to 500mA may be used to power up external circuitry The driver defaults to halfstep when the 5VDC output is used MOTOR ON OFF INPUT Terminal 10 This terminal is internally pulled up to 5VDC through a 10k ohm resistor When a logic 1 or no connection is applied the driver phase outputs are enabled and the motor is energized When a logic 0 is applied the driver phase outputs are disabled and the motor is de energized MOTOR PHASE OUTPUTS Terminals 1 2 13 14 These outputs can sink a peak of 15 Amperes or sink 10 Amperes continuously and stand off 250 VDC maximum MOTOR COMMON OUTPUTS Terminals 3 12 These outputs can source a peak current of 15 Amperes or source 10 Amperes continuously AMBIENT TEMPERATURE 0 to 50 degrees Celsius SHIPPI
3. current level is reached a low voltage is applied to maintain a suitable holding current level When a motor winding is DPFHPO001 Driver Packs are shipped 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 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 phase transistors resulting in blown transistors The addition of the from the factory with terminal 9 TVS Diodes suppresses these transients and protects the transistors against damage CLOCK AND DIRECTION CCW OPERATION DPFHP001 Driver Packs are shipped from the factory with terminals 6 and 5 assigned as CLOCK and DIRECTION inputs respectively Pulses applied t
