      What is part number for lid to suit 1239/20/4?

      Part number 1239L20 will suit any of 1239/20 series.

      Control power rating on the CM4000 series meter is different than what is stated in the specifications in CM4 manual

      Control power rating is different than what is shown in the CM4000 series user manual 

      Product Line
      CM4000 Series


      The control power for the CM4000 series Circuit Monitors is rated for a voltage range of 90-305V ac or 100-300V dc. It was our standard practice to publish these ratings. Recently a change was implemented to mark the circuit monitors with the nominal voltage ranges instead of the maximum range. As a result the meters now show a control power voltage range of 100-277 V ac or 125-250 V dc.
      If the customer needs a document with signature for their customer, you can send them the following document from John Straughn below.

      Please confirm that the Neutral can be connected to either the left hand or the right hand pole in a Masterpact 4-pole breaker.

      The 4 neutral pole is specific. So a circuit breaker either comes equipped with a neutral pole configured on the far right pole or the far left pole. The pole is marked and must be wired accordingly because the trip system for the neutral set up separate form the 3 phases.

      Yes.  According the UL White Book (Product Category DIVQ), multipole common trip circuit breakers rated 125/250V are suitable for use for a single-phase multiwire circuit, with or without the neutral connected to the load.  Courtesy of Mike Holt Enterprises 2008

      Motor Characterization procedure for resolver based non- BPH motors with Lexium Drive

      Goals and Symptoms

      The purpose of this resolution is to outline the steps necessary to setup a non-BPH motor (with resolver feedback) with a Lexium drive.

      Facts and Changes

      Proper commutation and position feedback are required to interface a particular servo drive and motor combination. When using Schneider Electric BPH motors and Lexium drives, this setup (or "characterization") process has already been completed and verified for the user. The electrical characteristics of the motor and resolver must be verified by Schneider Electric technical support personnel, prior to attempting this procedure.Familiarity with Unilink commissioning software, Hyperterm, and a copy of the drive user manual are required for this process.

      Causes and Fixes

      The following steps, in the order presented, need to be performed to complete the characterization.
      This procedure needs to be done only with the mechanical load disconnected from the motor.

      Verify Electrical Connections :
      A. Verify the required electrical connections for drive power, logic power, motor power and resolver as described in the Lexium drive user manual.
      B. Apply 24VDC logic and AC input power to confirm proper drive startup sequence and self-checks.
      Verify Resolver Feedback :
      A. Start Unilink software and connect to the drive. Insure that the drive is not enabled.
      B. Open the monitor screen. Manually rotate the motor shaft slowly in the clockwise direction (facing the motor shaft). The value of the shaft position (counts) should increase. The actual speed should be positive and mechanical angle of rotation should
      increase.If not, first ensure that DIR is set to 1 (clockwise rotation) by typing DIR followed by Enter' at the command prompt on the terminal screen.If position counts is decreasing for a clockwise rotation of the motor shaft, there is a problem with the feedback wiring and needs to be reversed. (Sin+ with Cos+ and Sin with Cos respectively)
      C. Disconnect from the drive.
      Enter motor characterization parameters (provided either directly by Schneider Electric technical support or by motor vendor and subsequently verified by Schneider Electric technical support).
      Connect to the drive using Hyperterm… The proper settings for the connection are:
      Bits Per Second: 9600
      Data Bits: 8
      Parity: None
      Stop Bits: 1
      Flow Control: None
      A. At the __ > prompt, enter all required motor parameters (L, MPOLES, MTYPE, etc.) For example, to enter a value of motor inductance L equal to 50mH, type L 50. To enter 6 motor poles, type MPOLES 6, followed by the <Enter> key.
      B. When finished, type SAVE.
      Perform MSET - the MSET process is required to insure proper commutation1. Note down the actual value for MPOLES (P).

      *** This MSET procedure is valid only for drive firmware version 5.51 and above***

      Connect to the drive using Hyperterm…
      A. Type OPMODE 2 followed by 'Enter' switch to digital torque mode
      B. Type EN to enable the drive
      C. Type ZERO - Motor shaft will jump to nearest pole position
      MPHASE value is automatically set.
      D. Type SAVE followed by 'Enter'
      E. Type COLDSTART followed by 'Enter'

      *** This MSET procedure is valid only for drive firmware version prior to 5.51 ***

      Connect to the drive using Hyperterm…
      A. Type MPOLES 0 followed by 'Enter' change MPOLES to 0 temporarily
      B. Type MPHASE 90 followed by 'Enter'
      C. Type OPMODE 2 switch to digital torque mode
      D. Record the motor nameplate value for Istall. Multiply this number by 0.25
      For example, if Istall = 2.2 then T = 2.2 x 0.25 = 0.55.
      At the - - > prompt, Type T and then the value computed above followed
      by 'Enter'.
      For this example, it would be T 0.55 followed by 'Enter'.
      E Type EN - Motor shaft will jump to nearest pole position.
      F. Type PFB - Two values will be returned separated by a space such as:
      12459560 317.
      The second value will range from 0 to 360 degrees. Record this second
      value 'X".
      G. Use the value from PFB in the following equation to determine the value
      for the offset angle (MPHASE).

      MPHASE = P/2 * X
      P = # of motor poles recorded at the start of this MSET procedure
      X = value from PFB recorded in Step F.
      If MPHASE calculated is greater than 360 degrees, keep subtracting
      multiples of 360 to get a value between 0 and 360.
      For the example in Step F:
      MPHASE = 6/2 * 317 = 951 - 360 - 360 = 231
      H. Enter the MPHASE angle calculated above. For the example above,
      type MPHASE 231 followed by 'Enter'.
      I. Type DIS followed by 'Enter' to disable the Drive.
      I . Type MPOLES P followed by 'Enter' to restore the actual value P for
      J. Type SAVE followed by 'Enter'
      K. Type COLDSTART followed by 'Enter'
      Perform CTUNE
      Connect to the drive using Hyperterm.
      The CTUNE function will automatically optimize the current loop tuning
      Using Hyperterm…
      A. Type EN to Enable the drive
      B. Type OPMODE 0
      C. Type CTUNE 1 the drive will perform a series of tests to optimize the
      current loop parameters.
      When finished, a list of parameters with their values will be displayed and
      the cursor will be at the command prompt.
      D. Type SAVE and exit Hyperterm screen.
      Test for proper operation of the axis as required for the application
      Connect motor shaft to the mechanical load
      Proceed with normal axis tuning

      NOTE 1: The MSET procedure may have to be repeated a couple of times to ensure proper MPHASE value. If the motor shaft does not jump promptly to a position during step 4, raise T by 10% and repeat steps 4.D through 4.I.

      NOTE 2: The maximum limit for L is 100mH. CTUNE procedure becomes ineffective for motors with stator inductance larger than 100 mH. Manual tuning of the current loop is necessary.
