2.3.  Product Features 
2.3.1.  Current Control 
•  Fully digital 
•  Sinusoidal commutation with vector control or trapezoidal commutation with encoder 
and/or digital Hall sensors 
•  12-bit current loop resolution 
•  Automatic gain scheduling, to compensate for variations in the DC bus power supply 
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 
•  CANopen for fast communication in a multi-axis distributed environment
