General Description
The  MDC010-050101  has  a  very  compact  design  with  a  high  efficiency  speed  controller  that  offers  a 
operating voltage of 50VDC, while maintaining an output current of 5A.  The amplifier also offers a large 
number of inputs and outputs such as the speed monitor, current limiting, speed ranges, direction of rota-
tion presetting, enable, operating status, etc.  While offering all these features the MDC010-050101 offers 
many protective features against overcurrent,...

The  input enables or disables the power stage.
If a voltage higher than 2.4V is applied to the  input, the amplifier is acti-
vated (Enable).  A speed ramp will be performed during acceleration.
Enable Input Voltage>2.4V
Motor Shaft Running
If the input is not connected (floating) or ground potential is applied to the 
 input, the power stage is high impedant and the motor shaft 
freewheels and slows down (Disable).
Disable Input not connected (floating)
Input set to Gnd
Input Voltage

The  input is used for setting the continuous output current limitation in the range 
of 0.5-10A.
The current set at the input  sill stay available for an indefinite period of time.
  Note
   The limiting calue should be below the rated motor current (max.continu\
ous current).

Status Indication 
The  output can be used to report the state of operational readiness or a fault condition to a 
master control unit.
  In normal cases (no fault) the output is switched to 5V.Ready (no fault) 5V
In case of a fault the output is switched to Ground.

amplifier must be disabled and the power stage temperature must fall below...

Protective Features
Undervoltage Protection
The power stage will be disabled in case the supply voltage +V
cc drops below 6VDC. To reset the fault 
condition the amplifier must be disabled and the supply voltage +V
cc must be higher than 6VDC.
Overvoltage Protection
The power stage will be disabled in case the supply voltage +V
cc rises above 56VDC.  To reset the fault 
condition the amplifier must be disabled and the supply voltage +V
cc must be lower than 54VDC.
Thermal Overload Protection
