operating range.
Voltage Error Message
00 Input voltage within operational range
01 Input voltage below operational range
10 Input voltage above operational range
11 Not used
5.2.5.5 Temperature error
This 2-bit signal is used to inform the user that the operational temperature is outside of allowable
running parameters. Any motion already in progress will continue until completed, but additional
movement request will not be allowed until the operational temperature returns within the normal
operating range.
Temperature Error Message
00 Temperature within operational range
01 Temperature below operational range
10 Temperature above operational range
11 Not used
5.2.5.6 Motion flag
This 1-bit signal is used to inform the user that the actuator is currently in motion.
5.2.5.7 Overload flag
This 1-bit signal is used to inform the user that thelast motion the actuator attempted caused an over
load condition. This occurs when the actuator determines the current set in the Current Limit signal
from the ACM is exceeded for a consecutive 50 ms. When this flag is set by the actuator the user
must reset the Motion Enable flag in the ACM before attempting additional motion from the actuator.
5.2.5.8 Backdrive flag
This 1-bit signal is used to inform the user that the actuator has determined positional movement in
the extension tube that was not commanded from the user. This can be caused from excessive static
load or vibration being applied to the actuator.
5.2.5.9 Parameter flag
This 1-bit signal is used to inform the user that one of the parameter signals in the ACM is outside
the allowed parameters the specific model will allow. To prevent damage to the actuator motion is
not allowed after this flag is set.
5.2.5.10 Saturation flag
This 1-bit signal is used to inform the user that the actuator is currently running within 10% of its
maximum capability. Additional speed or current needed from the application may not be able to be
obtained with the chosen actuator model.
5.2.5.11 Fatal error flag
This 1-bit signal is used to inform the user that the actuator needs service. If this flag is set power
can be reset to determine if the flag is resettable, but it is suggested to contact the factory for
additional support. To prevent possible additional damage motion is prohibited while this flag is set.
5.2.5.12 Factory use
The remaining 26 bits of the Actuator Feedback Message are used for factory calibration use only
and under normal operation will be returned with 0xFF.
