Drum Micro Master Parameter Table MM440   0.75KW 
Old series 6SE31(MM750) of micromasters became obsolete 
 
MM440 : makes the drum spinning during exposure. Drumdirection: when standing 
on the right of the SW(drummotor position) the drum spins clockwise during 
exposure. 
 
The 0.75 KW  drum motor is controlled by a micromaster.  In this case no additional 3 phase 
power supply is needed. 
•  The micromaster is switched (input 5-9) on by 
 the output signal : DRUMON   
•  The micromaster is also connected to the Emergency stop button on input 6.  
•  The MM440 has a complete different set of parameters compared with the old 31 series. 
•  Also another type of  brake resistor is needed. Resistor mounted on the frame.On the right 
side of the micromaster. 
•  The MM440 has a separately front panel (BOP = Basic Operator Panel) that has to be 
ordered with the MM440.  
•  The brake can be mounted on top of the electrical rack.
