or

Encoder
Error
The CPU failed to read an encoder pulse, or has not
received the expected signals in a certain amount of time.
Thus, the controller has lost its zero reference. It then
attempts to recover by doing a mechanical zero
calibration. If the mechanical zero calibration is
successful, this error is cleared, and normal operation
continues. If further errors prevent successful mechanical
zero calibration, this error is a fatal error and requires
user intervention.
Clear error by
cycling power.
13
Position
Error
Failure to reach commanded position within the timeout
period (5 minutes). After 10 minutes, the error will clear
and the controller will automatically retry the position
adjustment. If the error continues to occur for ten
consecutive times, no further retries will be attempted,
and the error will become a fatal error requiring user
intervention.
Wait 10 minutes,
or clear fatal error
by cycling power.
14
Over
Temperature
The motor thermistor indicates the motor case
temperature has reached approximately 90
°C (194°F).
This will stop motor operation until the motor case
temperature drops below approximately 80
°C (176°F) at
which point the error clears automatically.
Correct reason for
motor Over-
Temperature
condition.
21
Signal Loss
The Analog Input signal dropped more than 0.3 mA below
the low cal point. This error clears automatically when the
analog input signal returns to normal.
Correct reason for
low input signal.
22
Self-Test
Signal Error
The Analog Output signal and Analog Input signal at 0%
stroke position do not agree (refer to Self-Test Mode
description for further details).

Self-Test
Signal Error
The Analog Output signal and Analog Input signal at
100% stroke position do not agree (refer to Self-Test
Mode description for further details).
