General Provisions
PLDS880 is a DSP processor based digital driver of Servo-Step
Motor (SSM) with possibility of driver parameter PC adjustment via
USB interface. Driver may work both in servo mode and SM common
driver mode without encoder. In servo mode SSM is controlled as fully
functional servo motor with position and speed control. This allows
obtaining motor maximum moment output and excluding step skip at
overload. Driver is highly efficient, SSM rotation noise and vibration is
significantly reduced.
Device features integral SSM winding SC, encoder power supply SC,
SSM back EMF effect protection circuits; SSM mid-frequency resonance
compensator; power supply voltage polarity reversal protection and
SSM soft start; damper; STEP frequency generator and STEP inlet
frequency excess protection. Driver operates with STEP/DIR/ENABLE
standard protocol. All driver control inlets are optically isolated and
compatible with 2.5V, 3.3V, 5V logic levels. Also module has AUTO-
SLEEP mode that is started at STEP signal unavailability.
Driver is optimal choice for Purelogic R&D PL57/PL86 Series 2
phase bipolar servo-step motors. Operation with other 2 phase SSM for
instance Leadshine is also possible.
