Note: Motors with the Smart Encoder option set ERES automatically.
Changing the ERES value may cause unpredictable motor responses.
Note:
ERES is fixed at 4096 for Aries drives with Resolver option.

For linear servo motors, use the following equation to determine the proper
ERES, based on both the encoder resolution and the motor’s electrical (or
magnetic) pitch (DMEPIT).

The ERROR command gives a text-based status report of drive errors
(E25 through E46) that currently prevent the drive from enabling.
To re-enable the drive correct the specified fault, then reset the drive or cycle
power to it.
Table 46 contains the possible errors appearing in the text-based report and
their descriptions.
