2.3.2. Velocity Control
• Fully digital
• Programmable PI and FFW (feed forward) control filters
• Sample rate two times current loop sample time
• “On-the-fly” gain scheduling
• Automatic, manual and advanced manual tuning and determination of optimal gain and
phase margins
2.3.3. Position Control
• Programmable PIP control filter
• Programmable notch and low-pass filters
• Position follower mode for monitoring the motion of the slave axis relative to a master axis,
via an auxiliary encoder input
• Pulse-and-direction inputs
• Sample time – four times that of the current loop
• Fast event capturing inputs
• PT and PVT motion modes
• Position-based and time-based ECAM mode that supports a non-linear follower mode, in
which the motor tracks the master motion using an ECAM table stored in flash memory
• Dual (position/velocity) loop
• Fast output compare (OC)
2.3.4. Communication Options
Hornet and Bee users can use two communication options:
• RS-232 serial communication
• CAN for fast communication in a multi-axis distributed environment
2.3.5. Feedback Options
• Incremental Encoder – up to 20 Mega-Counts (5 Mega-Pulse) per second
• Digital Halls – up to 2 kHz
• Incremental Encoder with Digital Halls for commutation – up to 20 Mega-Counts per
second for encoder
• Interpolated Analog (Sine/Cosine) Encoder – up to 250 kHz (analog signal)
 Internal Interpolation - up to x4096
 Automatic Correction of amplitude mismatch, phase mismatch, signals offset
 Auxiliary emulated, unbuffered, single-ended, encoder output
