MMX (M-Max) How to Default and Program Drive

M-Max (MMX) Quick-Start Guide:

Introduction:

This guide sets up an M-Max (MMX) to be able to run a variety of configurations. For this guide default the drive to clear all parameter changes. Make sure to have motor name plate information on hand. You will need:

  • Motor Nominal Voltage
  • Motor Nominal (FLA) Rated Current
  • Motor Nominal Frequency
  • Motor Nominal RPM
  • Motor Power Factor (P.F.)
  • Motor Service Factor (S.F.)

 

Navigating the Menu and Changing Parameters:

The MMX menu navigation is unique and requires timing to change parameter values. The figure below shows the keypad screen. The next page shows the keypad interface and what the indicators represent.

 

 

Figure 1: MMX Keypad P1.1

Arrow Indicators:

  • READY: Indicates that DC-Bus and Enable Signals are present; drive can run
  • RUN: Indicates if the drive is running, does NOT mean motor has to be rotating
  • STOP: Drive is stopped and the motor is not being powered
  • ALARM: Indicates if there is an issue that may be arising, i.e. Current Limit
  • FAULT: Indicates that the drive has a fault condition present, i.e. Ext Fault
  • REF: Indicates the keypad Reference value, use for keypad speed ref. only
  • MON: Indicates Monitor menu, use to monitor Output Freq, Voltages, Inputs, etc.
  • PAR: Indicates Parameter menu, use to change any parameter and drive setting
  • FLT: Indicates Fault Menu, use to see drive status at time fault occurred
  • FWD: Indicates if drive is running in forward direction
  • REV: Indicates if drive is running in reverse direction
  • I/O: Indicates if drive is under I/O Terminal (Remote) Control for START/STOP signals
  • KEYPAD: Indicates if drive is under Keypad (Local) Control for START/STOP signals
  • BUS: Indicates if drive is under Fieldbus Control for START/STOP signals
 

 

 

Changing a Parameter Value:

Changing a parameter value in a MMX requires the user to wait until the value is displayed on screen. The example below shows how to change the value for P1.1.

 

Note: The MMX will always alternate between showing the Parameter location and the Parameter value. Changing values requires timing of the button presses.

 

Example: How to Change a Parameter on the MMX

Step 1: Changing from MON menu to PAR menu. Press the BACK/RESET button

Figure 2: Monitor (MON) Menu

Step 2: The screen will become blank except for the indicator arrows.

Figure 3: Menu Selection – MON Selected

 

 

 

Step 3: Use the ▼(down) arrows to change to the Parameter Menu (PAR).

Figure 4: Menu Selection - PAR selected

Step 4: Press OK button to select the Parameter Menu

Figure 5: Menu Location P1.1

Step 5: Wait till P1.1 value is displayed, the value will show “1” by default. Press OK button.

Step 6: Use the ▼(down) arrow to change to “0” value,

 

 

Figure 6: P1.1 Initial Value = 1

 

Step 7: Press the OK button to save the parameter value. Once saved, the “0” will stop, blinking. The display will resume showing the P1.1 and new value “0” in the original alternating fashion.

 

Step 8: Changing the parameter is complete

 

 

 

 

 

Defaulting the Drive:

Defaulting an MMX can be done by following the steps below. This process will clear any changes made to the drive. Motor nameplate values will be needed to reprogram the drive.

 

Step 1: Navigate to P1.1

 

 

Figure 7: Menu Location P1.1

 

Step 2: Use ▼(down) arrow to find parameter S4.2

Figure 8: Menu Location S4.2

 

Step 3: S4.2 is by default “0.” Change this parameter to “1.” After changing to “1” then press the OK button. The drive will then power cycle. You will also need to change P1.1 back to “0” to have access to all parameter groups again. The drive will automatically change S4.2 back to 0 after power cycling. No need to change back.  

 

Analog Inputs:

The MMX drive has 2 analog inputs, by default AI1 is 0-10VDC and AI2 is 4-20mA input. See the figure below for wiring to the inputs.

  • AI1 uses PIN1 (VCC), PIN2 (Potentiometer Variable Output) and PIN3 (GND)
  • AI2 uses PIN4 (Signal Plus [+]) and PIN5 (Signal Negative [-])

 

 

 

 

Programming the Drive:

Default the drive by going to parameters and set S4.2 to “1”. Next set P1.1 to “0”. Next select the application at P1.2 to match your motor load/application. Continue to set the following parameters found in the table below. Once all the parameters in the table are completed, choose the correct yellow highlighted sections on the following pages to complete programming the drive. Follow the steps exactly. 

 

 

Standard Parameters Table:

 

Choose Application Mode Based on site application. If you cannot determine which application mode fits best, use BASIC [0]. Set parameters to value in respective column. This must be done for any Control Scheme
