    The drive first converts incoming AC power to DC through a rectifier bridge, creating an internal DC bus voltage. Then the inverter circuit converts the DC back to AC again to power the motor. The special inverter can vary its output frequency and voltage according to the desired motor speed.
  • Page 37 With the free-setting torque curve feature, you can specify a series of data points that will define a custom torque curve to fit your appli- cation.
  • Page 38 1-3-7 Braking In general, braking is a force that attempts to slow or stop motor rotation. So it is associated with motor deceleration, but may also occur even when the load attempts to drive the motor faster than the desired speed (overhauling). If you need the motor and load to decelerate quicker than their natural deceleration during coasting, we recommend installing a braking resistor.
  • Page 39 FWD and REV commands determine the direction before the motion starts. Note The MX2 can move loads in both directions. However, it is not designed for use in servo-type applications that use a bipolar velocity signal that deter- mines direction.
  • Page 40: Frequently Asked Questions

    Q. Although the MX2 inverter is a variable speed drive, can I use it in a fixed- speed application? A. Yes, sometimes an inverter can be used simply as a "soft-start" device, providing controlled acceleration and deceleration to a fixed speed.

    When enabled, the built-in PID loop calculates an ideal inverter output value to cause a loop feedback process variable (PV) to move closer in value to the set point (SP). The frequency command serves as the SP. The PID loop algo- rithm will read the analog input for the process variable (you specify the cur- rent or voltage input) and calculate the output.
  • Page 110 When enabled, the PID loop calculates the ideal output frequency to minimize the loop error. This means we no longer command the inverter to run at a par- ticular frequency, but we specify the ideal value for the process variable. That ideal value is called the setpoint, and is specified in the units of the external process variable.

  • Page 349: Ce-Emc Installation Guidelines

    You are required to satisfy the EMC directive (2004/108/EC) when using an MX2 inverter in an EU country. To satisfy the EMC directive and to comply with standard, you need to use a dedicated EMC filter suitable for each model, and follow the guidelines in this section.
  • Page 350 CE-EMC Installation Guidelines Section D-1 • Allow the effective shield area of these lines to remain as large as possi- ble; i.e., do not strip away the shield (screen) further away from the cable end than absolutely necessary. • With integrated systems (for example, when the adjustable frequency...

    • Frequency variation ±4% or less • Voltage distortion THD =10% or less 2. Installation measure: • Use a filter designed for MX2 inverter. Refer to the instruction of the appli- cable external EMC filter. 3. Wiring: • Shielded wire (screened cable) is required for motor wiring, and the length must be 20 meter or less.

    Removing the voltage from both terminals GS1 and GS2 disables the drive output, i.e. the power supply to the motor is cut by stopping the switching of the output transistors in a safe way. EDM output is activated when GS1 and GS2 is given to the drive.
  • Page 356: Periodical Check

    PL=d of the inverter is to be achieved. Periodical check Since the drive stops even one of the GS1 or GS2 is interrupted, it is to be reconfirmed that there is not faiure in the path of GS1 and GS2 periodically.
