6.4.2.4. Equation Notes
1. Cnts = the number of encoder (or resolver equivalent) counts
per revolution.
Where: Encoder counts = Encoder lines * 4.
Resolver counts = 2^16 * MResPoles/2
2. CUCT = The control unit cycle time (IDN 1) in ms.
3. The units "CUCT/ms" is the number of CUCT periods per ms.
For example, a 2 ms CUCT has 1/2 a CUCT per 1 ms.
4. Remember the following when monitoring a SERCOS interface
drive through the serial port:
− The SERCOS interface address is also the serial
MultiDrop address
− SERCOS interface operation changes the UNITS variable
to internal units
− The SERCOS interface version of the SERVO
STAR is not
enabled automatically on power-up, even with the drive
address set to 0.
