4 Quadrent full wave SCR control allows
regeneration to the AC power line.
Peak torque capability allows for 250%of
nominal load.
Current regulated shunt field supply with
field economy feture saves power during light trrafic conditions.
Microprocessor-based regulator allows
software configuration of digital system parameters.
Acceleration "feed forward"
enhances ride quality.
Fully adjustable Sinusoidal curve
acceleration characterstics.Each jerk and acceleration parameter is individually
adjustable to optimize for existing or new machines.
Unique current loop algorithms are executed
every 2.8milliseconds.These advanced algorithms provide continious gain control that
guarantees identical performance during discontinious and continious current operation.
Fully digital interface between control and
drive provides high speed communication of digital speed patern,travel parameterand
fault/set-up data.
Absolute position servo computes actual
position information for comparison with desired position to a resoltion of 1/50".
High speed feedback servo directly
communicates via the high speed digital link ensuring optimum compliance to dictated
velocity profile.
Protection Features
Field loss products.
Controlled multi-pulse firing technique to
assure SCR condition on notched and noisy power lines.
urge protection is provided on all input
connections preserving all electrical drive components for transient voltage protection.
Programmed memory protection at power
loss.Faults and parameters are stored by the drive/control even during power failure .
AC lines DC bus currrent limiting fuses .
Instanteous over-current protection.
Phase loss protection.
- Automatic test of fuses,SCR's and other vital
components.
