							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, undervoltage and overvoltage, short ciruit and thermal over-
load to ensure the controller runs correctly.  Anaheim Automation also offers an MDC010-EVALBOARD

The digital inputs  [20] and  [21] determine both, the operation mode (digital speed 
controller or digital sepeed actuator) and the speed range in speed set\
 value mode.

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).

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).
Set Value Current Pin Number [25]

To  parameterize  the  preferred  current 
limiting value, an external resistor (at least 
62.5 mW) between current limiting input 
 Pin [25] and ground

							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.
Fault (not ready) 0V (Gnd)
Possible reasons for a fault message:
 UndervoltageFault message occurs in case supply voltage +V56VDC.  To reset the fault condition the 
amplifier must be disabled and the power stage temperature must fall below 80deg Celcius.
Thermal 
Overload Fault message occurs in case power stage temperature is>100deg Celcius.  
To reset the 
fault condition the amplifier must be disable and the power stage temperature must fall be -
low 80deg Celcius.
Invalid Hall  Sensor 
SIgnals The amplifier recognizes invalid conditions at the Hall Sensor inputs.  
To reset the fault con-
dition the amplifier must be disable and the Hall Sensors must be wired correctly .
The output  is protected against continuous short circuit.

							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
The power stage will be disabled in case the power stage temperature exc\
eeds 100
0C.  To reset the fault 
condition the amplifier must be disabled and the power stage temperature must fall to 800C.
Invalid Hall Sensor Signals
The power stage will be disabled in case invalid conditions at the hall sensor inputs occur.  To reset the 
fault condition the amplifier must be disabled and the hall sensors must be wired correctly .
Blockage Protection
If the motor shaft is blocked for longer than 1.5s, the current limit is set to the predetermined value at the 
 input.
Definition : A speed lower than 4154rpm (motor with 1 pole pair) occurs for longer 
than 1.5s.
 Note:
  - No fault message occurs at the  output if blockage protection is active.
Current Limitation
The motor current will be limited to 0.5-10A depending  on the value applied  to the input  by means of a cycle-to-cycle limitation.
 Note:
  - No fault message occurs at the  output if current limitation is active.
