Drives Features • Fast-acting Current Limit and Bus Voltage Regulation result in maximum accel/decel without tripping. • High-speed analog inputs improve drive response to torque or speed commands. • Programming flexibility allows parameters to be linked within the drive. • Flying Start delivers smooth and instantaneous connection into rotating loads, regardless of commanded direction, without the need for any speed feedback. • Integral Process PI Control can eliminate the need for a separate process loop controller. • Inertia Ride-Through offers tripless operation during a prolonged power outage by using the rotating energy that is stored in high inertia, low-friction loads. • Position Indexer/Speed Profiler uses a 16-step indexer to provide point-to-point positioning or velocity profiling based on encoder counts, digital inputs, parameter levels, or time. • TorqProve™ assures control of the load when transferring control between the drive and a mechanical brake. • Speed Regulation - Open Loop or Closed Loop - Slip Compensation delivers a minimum 0.5% speed regulation without feedback hardware. - Droop allows drives to load share without fighting each other. - Encoder Feedback provides up to 0.001% speed regulation for the tightest application requirements. • Torque Regulation - Open Loop or Closed Loop - Open Loop torque regulation provides 5% regulation. - Encoder Feedback provides 2% regulation and the ability to hold full load at zero speed.
The following tables list the watts loss data for drives running at full load, full speed, and default carrier frequency. Internal watts are those dissipated by the control structure of the drive and will be dissipated into the cabinet regardless of mounting style. External watts are those dissipated directly through the heatsink and will be outside the cabinet for flange mount and inside the cabinet for other mounting types.
