  • Page 5: General Description

    The Centent CN0165 is a high resolution step motor drive designed for the operation of hybrid PM step motors rated from 0.1 to 20 amps per phase. The CN0165 operates on a supply voltage of 18-80 volts DC. Drive output current ranges from 0.1 to 10 amps per phase.

  • Page 6: Location Of Components

    Figure 1 - Component location (3) FAULT LED This light emitting diode turns on when the CN0165 is in a fault mode. The fault status is also available on the Fault/Reset Terminal of the connector (see page ) . A fault condition is cleared by shorting the Fault/Reset Terminal to ground potential or by recycling the power supply (power off, power on).

  • Page 7: Installation

    If this occurs it will be necessary to provide additional heat sinking. As a practical guide, additional heat sinking will be necessary for the CN0165 if it is operated at three amps or more. A fan to force air circulation through the heat sink may also be required.

  • Page 8: Power Supply

    If the supply cannot absorb this power, the voltage generated may exceed the 80 volt limit of the CN0165, thus damaging the drive and power supply. To protect the drive and power supply, the user may connect an external zener diode...

    If the case temperature is low immediately after a reset occurs, the cause is a short circuit. Do not continue to operate the CN0165 if it is resetting due to overheating. Heat sinking must be provided to prevent the drive from repeatedly entering thermal shutdown.

  • Page 14: Direction

    CENTENT CN0165 MICROSTEP DRIVE DIRECTION INPUT Terminal 8 is the Direction Input. This input is sampled by the CN0165 on every step pulse input to determine which direction the step motor will move. The state of the Direction Input must be held one microsecond after the active edge of the Step Pulse Input to insure correct direction.

The maximum phase current of 10 amps is obtained with no resistor installed across the terminals.

  • Page 19: Standby Current Trimpot

    STANDBY CURRENT TRIMPOT STANDBY (REAR VIEW) The Standby Trimpot sets the current level of the CN0165 when the motor is not stepping. Turning the potentiometer to the full clockwise position disables Current Standby. The full counter-clockwise position results in 100% Current Standby (freewheeling).

  • Page 20: Fault Led

    POWER ON RESET The Power-on Reset circuitry of the CN0165 insures that the drive turns on in an organized manner. The motor phase outputs are held low (ground) and the internal counters are held to microstep zero until the power supply voltage rises to the minimum operating voltage level of the drive.

  • Page 21: Anti-Resonance

    Most step motors are prone to parametric instability or resonance when rotating at a rate of 4 to 15 revolutions (800 to 3000 full steps) per second. The CN0165 incorporates a mid-band anti-resonance compensation circuit to close the loop on this instability and damp it out electronically.

  • Page 22: Torque And Power

    Because any torsional oscillation implies the acceleration and deceleration of a mass, torque that otherwise would have been available for useful work is wasted to sustain this oscillation. The CN0165’s anti-resonance compensation circuit closes the loop on this instability and dampens it out electronically. Since the motor will not sustain oscillation, torque previously wasted is now available to the application.

  • Page 23: Motor Winding Configuration

    The intersection of this slope and the speed axis determines the maximum speed of the motor. THE CENTENT CN0165 DRIVE IS CAPABLE OF RUNNING STEP MOTORS AT SPEEDS HIGH ENOUGH TO CAUSE DAMAGE TO MOTOR SHAFT BEARINGS.
  • Page 24 The parallel configuration doubles high speed torque. Motor phase currents are twice those in a series connected motor. This doubles power supply requirements and thus results in higher motor and drive temperatures. For parallel operation the phase current level of the CN0165 is set to the motor's nameplate phase current rating.

  • Page 27: Motor And Drive Heating

    PERFORMANCE MOTOR AND DRIVE HEATING Motor and drive heating is equivalent to the difference between the electrical power input to the system and the motor's mechanical power output. The ratio of output to input power defines the system efficiency. The power losses that lower efficiency are dependent on motor speed, load and winding configuration, the power supply voltage, current set value, drive losses and other factors.
