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.
