DESCRIPTION
The Motor Drive Controller (MDC) regulates motor speed by varying an
isolated DC control signal to a motor drive system. There are two modes of
operation, Master and Follower.
Master Mode provides control of a motor directly via programmed speed
setpoints in the MDC. Regulation is maintained by a feedback frequency to the
MDC taken from the motor shaft or a downstream shaft pulse encoder. Follower
Mode controls a motor’s speed as a ratio to a second motor’s speed or outside
frequency source. Ratio setpoints are programmed into the MDC causing the
motor to “follow” the lead motor or frequency at a fixed speed ratio.
Master Mode has two speed setpoints and two ramp setpoints. Follower
Mode has two ratio setpoints and two ramp setpoints. Both modes share a jog
speed setpoint and a jog ramp setpoint. All setpoints are retained in non-volatile
memory when the unit is powered down.
The Motor Drive Controller has the added feature of allowing real time
adjustment of the Speed (Master Mode) or Ratio (Follower Mode) setpoint
while the unit is operating a motor drive system. The setpoint may be adjusted
via the front panel keypad using the “Up” or “Down” arrow keys, or via 2 User
Inputs programmed for increment setpoint and decrement setpoint.
User flexibility is provided through the two-line by eight-character
alphanumeric display. The display features English language menus for easy
viewing and simplified programming. The four scroll-through indication
displays can be programmed to show various parameters and to automatically
scroll, if desired. A program disable DIP switch used with an external User Input
can be utilized to protect the settings and guarantee that no unwanted changes
occur during operation.
There are five dedicated control inputs on the MDC:
RUN
RAMP STOP
FAST STOP
JOG
OPEN LOOP
There are six programmable control inputs: two front panel function keys and
four remote user inputs. The F1 and F2 keys are factory programmed for RUN
and R-STOP respectively. This eliminates the need for external switches in
some applications.
There are three solid state outputs, two are programmable alarms and one is
a dedicated Drive Enable output. Programmable alarm functions include:
High Alarm
Low Alarm
Deviation Alarm
Zero Speed
Disabled
These may be programmed for boundary or latching operation, high or low
acting.
Changing speed setpoints and programming information is easily
accomplished by scrolling through menus and selecting the correct parameter.
There are three main modules or menu loops:
Display Module
User Setpoint Module
Programming Module
Scaling is accomplished by entering the desired values for feedback pulses
per revolution (PPR), the maximum RPM, and the maximum display value.
