Cello Installation Guide
MAN-CELIG (Ver. 1.5)
2.2.3
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 current loop
Fast event capturing inputs
2.2.4
Advanced Position Control (Advanced model only)
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
PT and PVT motion modes
Dual (position/velocity) loop
Fast output compare (OC)
2.2.5
Communication Options
Depending on the application, Cello users can select from two communication options:
RS-232 serial communication
CANopen for fast communication in a multi-axis distributed environment
