                          hide show

                          What are the wiring terminals on the IEC LRD* overload relays?

                          Product Line:
                          Tesys D line Overload Relays
                          The normally closed overload contact are terminals 95 & 96; and the normally open overload contact are terminals 97 & 98.
                          T1 T2 and T3 are the load terminals. 

                          The normally closed control circuit contact will open when there is a fault, this contact is typically used in series with the control circuit. 

                          The normally open trip signal contact closes when a fault occurs which is typically used to control a pilot light, or alarm. 


                          What is the Din rail terminal block to suit the LRD12?

                          The LAD7B106 fits the LRD01 to LRD35 range.

                          What is the alternative for the PDL Thermal Overload 56T9092 ?

                           The alternative is LRD05 (Note - these are not direct replacements)

                          What is the difference between the LA7D305 and LAD7305, remote control reset mechanism by flexible cable?

                          Identifying differences between two similar part numbers.

                          Product Line:
                          IEC contactors and starters

                          Products sold and used in the United States

                          Choosing the correct part number

                          LAD7305 is for use on LRD01 to LRD35 , LR3D01 to LR3D35, and LRD313 to LRD365.
                          LA7D305 is for use on all other relays (except LRD01 to LRD35 and LR3D01 to LR3D35).


                          What is the difference between LAD703 and LA7D03

                          Identifying differences between two similar part numbers

                          Product Line:
                          IEC contactors and starters

                          Products sold and used in the United States

                          Identifying differences between two similar part numbers

                          Both will remotely stop (trip) or electrically reset the overload, however;
                          LAD703 is used on Tesys overload LRD01 through LRD35 and LR3D01 to LR3D35.
                          LA7D03 is used on all other LR*D overload relays other than LRD01 to LRD35 and LR3D01 to LR3D35.


                          Can the LRD01 to LRD35 range be put back to manual from automatic.

                          This LRD range cannot be put back to Manual reset, once the overlaod has been changed from Manual (factory default) to Automatic.

                          Is there a LE1M35N705 alternative or can coil be swapped out

                          What is the alternative for the PDL 56T9062

                           The alternative is LRD05. Note - these are not direct replacements and can not be used on the old DOL contactors.

                          Is there a direct replacement for TR2D09307 overload?

                          There is no direct replacement for TR2D09307 but alternative is LRD07 ( will not fit to existing contactor)

                          Alternative Overload for the PDL56T992 (6.0-9.2A)

                          Either go for the LRD12 (5.0-8.0A) or the LRD14 (7.0-10.0A) depending on the size of the motor. This will not fit the old 56 Series DOL starter

                          What is the setting range for an LRD350

                           The setting range is  37 - 50A

                          Is there a replacemnet for the old DOL motor starters like LE1D12U7R10?

                          Product Line:

                          The LXM05 capacitors should be charged prior to sending a run command to the motor.

                          What is the alternative for PDL56T9120 overload?

                          The alternative is LRD16 but this will not fit the contactor in the 56 series starter as it is for the LC1D range of contactors. The PDL56T9120 is no longer available.
                          The new range of 56 series starters, 56DOL, have LC1D contactors and LRD overloads (not fitted).

                          We do not offer any motors with the same exact frame size so we can only match the speed and torque specs of the motor. 
                          The new motor will be a BMH1003P01F2A, which has a higher torque (8.2 N.m instead of 6.6 N.m and a slightly higher rotor inertia (9.405 Kg cm2 instead of 8 Kg cm2) 
                          If LXM05 servo drive is used, you can keep it as it is compatible with the new BMH motor.

                          - Encodeur cable: VW3M8102R30 
                          - CANOpen card: VW3A3608 (if the control is done via CANOpen) 
                          - Termination RJ45 resistor: TCSCAR013M120 (for CANOpen control) 

                          You might have to update the motor firmware if the date of manufacture DOM is older than 15.07.2009 (verify motor name plate to get DOM). 

                          What's the replacement for the LXM05AD17M2 drive + SER3916 motor?

                          What is the replacement for the LXM05AD17M2 drive and SER3916 motor?

                          Product Line:

                          The replacement for the obsolete LXM05AD17M2 drive is a LXM32MD18M2 and a VW3M3403 encoder card. 
                          You can keep the motor, the power cable and the encoder cable but you need to change the connector of the encoder cable on the drive's side. 
                          Please note that the LXM32 does not have the same form factor as the LXM05 and adjustments to the drive's configuration have to be done. 

                          Does the Lexium 05 support BMH motors?

                          No, BMH motors are not compatible with Lexium 05 drives due to the type of encoder that is used in these motors.
                          If a BMH motor is connected to a Lexium 05, the drive will display fault 7120 which indicates that invalid motor data has been read. 

                          What is the alternative to the PDL56T992 Overload

                          the LRD12 is the same rated overload to suit the current range of 56 series DOL starters but will not fit on the old DOL starter the 56T992 was used for.                                                                                                                                                                                                                                      

                          What is the replacement for LXM05CU70M2 drive and BRH0852M00A2A motor?

                          What is the replacement for the LXM05CU70M2 drive and BRH0852M00A2A motor?

                          Product Line:

                          The replacement would be a LXM32CU90M2 servo drive and a BMH1001T06A2A servo motor.
                          Cables would be:
                          - Power cable: VW3M5101R15

                          - Encoder cable: VW3M8102R15

                          Replacement for Lexium 05 drive with part number LXM05AD42M3X

                          Replacement for LXM05AD42M3X

                          Product Line:

                          The corresponding part number to replace a LXM05AD14N4 will be a LXM32MD30N4 in terms of current rating.
                          If CANOpen was used to control the LXM05, a CANOpen card has to be added: VW3A3608
                          If motor's date of manufacture (DOM) is older than 15.07.2009, a firmware upgrade of the motor is required to work with the new LXM32 drive.
