This PowerPoint presentation explains the differences between different types of servo motor feedback devices, including:
The differences between absolute and incremental devices.
The differences between analog and digital devices.
Typical…
Commutation is the means by which a servo drive controls the torque of a motor by determining the position of the motor and applying current to the appropriate motor phases. If the rotor position of the motor is not determined correctly or the…
First to review what F402 means:
Analog signal amplitude for resolver or sine encoder feedback is out of range, either too low or too high.
To troubleshoot:
Check primary feedback (X10 connection), for resolver and sine/cos encoder only.
The setting for FB1.ENCRES (Rotary Encoder Resolution) for a resolver is set automatically in Workbench to a value of 32768 * FB1.POLES. So it is set to 65536 for a 2-pole resolver or 131072 for a 4-pole resolver. A resolver does not have…
