  • Page 15: Theory

    THEORY DESCRIPTION OF AC MOTOR OPERATION Three phase AC motors are comprised of two major components, the stator and the rotor. The stator is a set of three electrical windings held stationary in the motor housing. The rotor is a metal cylinder, fixed to the motor drive shaft, which rotates within the stator.
  • Page 16 If the frequency applied to the motor is increased while the voltage remains constant, torque capability will decrease as speed increases. This will cause the horsepower capability of the motor to remain approximately constant. Motors run in this mode when operated above base speed, where drive output voltage is limited by the input line voltage.

  • Page 17: Drive Function Description

    "Variable torque" refers to the fact that the torque required varies with the square of the speed. Also, the horsepower required varies with the cube of the speed, resulting in a large reduction in horsepower for even a small reduction in speed. It is easily seen that substantial energy savings can be achieved by reducing the speed of a fan or pump.
  • Page 18 6.2.3 MC1000 INPUTS AND OUTPUTS The drive has two analog inputs (0-10 VDC and 4-20 mA) that can be used for speed reference, PID setpoint reference, or PID feedback. A speed potentiometer (10,000 Ohm) can be used with the 0-10 VDC input.
  • Page 19 The following describes the possible relay output settings: NONE This setting disables the relay output. The relay energizes when the drive is given a START command, and remains energized until: a STOP command is given and the output frequency has decelerated to 0.5 Hz, the drive has "tripped", or the input voltage is removed.

  • Page 49: Description Of Parameters

    18.0 DESCRIPTION OF PARAMETERS (LINE VOLTAGE) LINE VOLTS This parameter calibrates the drive for the correct input voltage, and can be set to AUTO, HIGH, or LOW. When set to AUTO, the drive measures the DC bus voltage when power is applied and automatically calibrates itself according to the measured value (DC bus voltage is equal to input voltage multiplied by 1.4).
  • Page 50 SPEED #1-#4 (PRESET SPEEDS #1, #2, #3, AND #4) PRESET SPEEDS are only active when the drive is in AUTO mode, and are activated via contact closures between terminal TB-2 and terminals TB-13A, TB-13B, and TB-13C. These terminals must be programmed as preset speed selects using Parameters 47 - 49: TB13A, TB13B, and TB13C.
  • Page 51 Example: The critical frequency is 21 Hz, and a bandwidth of 2 Hz is desired. Therefore, set SKIP #1 to 20 Hz and set SKIP BANDWIDTH to 2 Hz. This results in a speed range from 20 Hz to 22 Hz that the drive will not operate within continuously.

  • Page 53 DC BRAKE (DC BRAKE VOLTAGE) DC braking creates a braking torque by injecting DC voltage into the motor. This parameter set the magnitude of that DC voltage. The point at which the drive applies DC braking to the motor depends on which STOP mode is programmed (either COAST or RAMP, see Parameter 26 - STOP).
  • Page 54 CURRENT (CURRENT LIMIT) The current limit setting determines the maximum value of the drive's output current. This is usually done to limit motor torque capability. For most applications the current limit is maintained at the maximum setting. Depending on the setting of Parameter 0 - LINE VOLTS, the drive is capable of delivering 150% or 180% of rated output current.
  • Page 55 The "speed-compensated" thermal overload circuit offers additional protection from high load conditions at low speeds, where motor cooling is often less effective (e.g., motors with shaft-mounted fans). As seen on the diagram below, the drive reduces the allowable continuous output current when operating at frequencies less than 30 Hz.
  • Page 56 BASE (BASE FREQUENCY) The BASE FREQUENCY determine the V/Hz ratio by setting the frequency at which the drive will out- put full voltage to the motor. For most applications the base frequency should be set to match the motor's rated frequency. For example, if the drive is rated for 460 VAC output, and the BASE FREQUENCY is set to 60 Hz, the drive will maintain a constant ratio of 7.66 V/Hz (except when AC BOOST or FX BOOST are active, see Parameters 19 and 20) from 0 Hz to 60 Hz.
  • Page 57 AC BOOST (AC BOOST) AC BOOST is similar to FX BOOST, but is only active when the drive is accelerating. During acceleration, the output voltage is increased according to the setting of AC BOOST, which increases motor torque. Refer to the diagram below. AC BOOST, like FX BOOST, is used in applications with high-inertia loads. FX AND AC BOOST AC BOOST FX BOOST...
  • Page 58 TORQUE (TORQUE CURVE SELECTION) This parameter is used to select whether the output of the drive follows a constant or variable V/Hz curve. The following selections are available: CONSTANT Use for constant torque applications to optimize torque. VARIABLE Use for variable torque applications to optimize energy savings. CT/NOCMP Use for constant torque applications that require full overload capacity at low speeds (see Parameter 17 - MOTOR OL).

  • Page 63 TB5 MIN (TERMINAL TB-5 INPUT) This parameter selects the output frequency of the drive that will correspond to the minimum analog speed reference input (0 VDC or 4 mA). This parameter is used in conjunction with Parameter 36 - TB5 MAX to define a speed range for the drive that corresponds to the analog speed reference input (0 - 10 VDC or 4 - 20 mA).
  • Page 64 @TB10A (TERMINAL TB-10A SCALING) This parameter scales the analog output signal at TB-10A. This setting is the output frequency that is indi- cated when the TB-10A output measures 10 VDC. Example: The drive is connected to a control system that requires a 0-5 VDC signal to indicate 0-60 Hz output frequency.
  • Page 65 TB13B (TB-13B INPUT FUNCTION) This parameter is used to select the function of terminal TB-13B. Closing TB- 13B to TB-2 activates the TB-13B input function. The following functions can be selected. NONE Disables the TB-13B function. 0-10VDC Selects 0-10 VDC as the AUTO speed reference input. The 0-10 VDC signal is wired to TB-5A and TB-2.
  • Page 66 TB13D EXT (TB-13D - EXTERNAL FAULT) This parameter selects the operation of the EXTERNAL FAULT function for TB-13D. FAULT Sets TB-13D as a normally open contact. Closing TB-13D to TB-2 will cause the drive to trip on an EXTERNAL FAULT. /FAULT Sets TB-13D as a normally closed contact.

Once the current limit relay is energized, it remains energized for a minimum of 500ms, regardless of whether the drive is still in current limit. At the end ofthe 500ms interval, the relay will de-energize if the drive is no longer in current limit.
  • Page 68 SERIAL (SERIAL COMMUNICATIONS) This parameter is used to activate serial communications. When using this feature, the drive can communicate with a personal computer (PC), programmable logic controller (PLC), or other external device that utilizes RS-485 serial communications for control.
