PERFORMANCE FEATURES
• Solid State Full Wave Power Bridge -Uses generously rated power semiconductors for
Maximum reliability and long life.
• Inner Current Loop Regulator - Inherent high bandwidth capability for fast response.
• Fusing - Both AC lines fused for maximum protection in case of short circuit.
• AC Line Filter and Transient Voltage Suppressor Network - Eliminates interaction
between other drives or AC equipment.
• Current Limit Ranges - Selectable current limit ranges to match the drive to the motor
being used. Provides smooth acceleration of high inertia loads.
• Speed Regulator - 1 % accuracy armature voltage feedback with IR compensation
• Current (Torque) Regulator -
2% accuracy armature current regulator allows the user to control motor torque instead of
speed.
• Circuit Board Indicator – A Light emitting diode (LED) on the control board indicate when
the drive is active in the Run Mode.
•
• UL/cUL - All Focus 1 Drives are UL/cUL listed.
• One cannot make a connection to ground or a grounded device to any terminal o
connection point to the Focus 1 Non-Regenerative Drive without causing driv
damage. Such failures unfortunately cannot be warranted.
• See Ways of Achieving Isolation on page 60 of this manual
