Overview

Use inverter built in PLC function to decode motor selections, use inverter inbuilt feature to control forward movement and motor 1/2 selection. DWEZ with use relay output to activate motor 1/2 selection and to monitor single 300Hz current limit. The DWEZ currently limit alarm will occur if current is greater than Percentage about when output speed is greater than percentage amount.

Motor 1 = 50Hz               S8 Inactive for Motor 1 and 50Hz

Motor 2 = 300Hz             S8 Active for Motor 2 and 300Hz

Inputs S1-S2 select motor frequency by controlling M3-M4 output

Inputs S3-S4 select motor single or dual, only 300Hz can be dual

Input S8 also selects between 50Hz and 300Hz speed selection and Motor 1/2

Output M3-M4 which feeds S8 selects Motor 1(50Hz) when inactive or Motor 2(300Mz) when active, derived when both S1 and S2 are inactive and driven from DWEZ program.

Output M5-M6 is to indicate when Motor 2 is selected, for monitoring purposes only.

IO Required from spec PRJ-133 Specification for Spindle Motor Protection Improvement v4.pdf

Inputs   FWD Inverter Forward accel to motor speed on high, decel to zero on low

MI1 50Hz Spindle Select

MI2 50Hz Spindle Select

MI3 Single Motor On

MI4 Second Motor On

RST Reset Fault

RTO Resistor Thermal Overload

All inputs are 24v Active

STO Safe Torque Off (linked to Estop circuit). Volts-free contact

Outputs              Volts free relays

INVOK Inverter OK                        MC-MB or M3-M4

0HZ Inverter at Zero Speed         M1-M2

GA700 electrical connections for STO will be independent of Inputs and output and must be Volts free contacts, use a relay to operation for active signal if required.

STO Safe Torque Off (linked to Estop circuit). Volts-free contact

GA700 parameters should be setup for 2 motor Control, external fault, fwd run operation, fixed frequency operation from keypad?

This will using inputs and outputs

Inputs

S1          DWEZ set to 90, see below

S2          DWEZ set to 91, see below

S3          DWEZ set to 92, see below

S4          DWEZ set to 93, see below

S5          FWD Inverter Forward Accel to motor speed on high, Decel to zero on low

S6          RST Reset Fault

S7          RTO Resistor Thermal Overload

S8          Motor 2 Selection

Outputs              Volts free relays

MC-MB               INVOK Inverter OK         

M1-M2               0HZ Inverter at Zero Speed

M3-M4               DWEZ DO2 output wired to S8 Motor 2 Selection

M5-M6               Motor 2 Selection Confirmed Output

Motor 1              1x 50Hz

Motor 2              2x 300Hz            NB set to higher current demand, for two motors

This is as tested

DWEZ should be set up for the following functions

S1          MI1 50Hz Spindle Select

S2          MI2 50Hz Spindle Select

S3          MI3 Single Motor On

S4          MI4 Second Motor On

DWEZ PLC Functions

IF S1(MI1)=0 && S2(MI2)=0 THEN 300Hz ELSE 50Hz motor                                                       NOR

IF S3(MI3)=1 && S4(MI4)=1 THEN Dual motor control ELSE Single motor control                AND

IF 50Hz selected and Dual motor selected then error, inhibit operation

IF 300Hz and Single motor then monitor current and error if current exceeds limit

300Hz set as Motor 2 option, use VMF DI1 for this purpose

DWEZ Fault 1     Dual 50Hz motor selected, not allowed                              DWFL

                            This means 50Hz Dual motor inhibits forward operation.

DWEZ Fault 2     Single 300Hz over current, as defined in Q1-01                 DWF2

In Single 300Hz motor the inverter is set to Dual current level (4A) in parameters and  DWEZ monitors lower value.

Use Q1-01 to set percentage of maximum current allow before fault triggered, current setting is 75% = Approx. 3A (for 300Hz motor 4A is max current setting 2x 2A)

Use Q1-02 to set percentage of maximum speed below which current limit is set to higher inverter built in value, current setting 20% = 60Hz
