FAQ – ACON/PCON-CY – Battery Alarm Output
April 17th, 2009 Posted in FAQ
Q: The PIO patterns of ACON/PCON-CY controllers include the “standard type” and “proximity type.” What are the differences?
A: How the complete signal is output is different between the standard type and proximity type. With the standard type, the position complete signal is output when the servo is OFF, therefore, the signal is not output even when the actuator is at the specified position. With the proximity type, however, the complete signal is output based on the position, which means that the signal is output even when the actuator is manually moved to the specified position while the servo is OFF.
If the proximity PIO pattern is selected and the home is set as the specified position, the complete signal is output when the power has been turned on and home return performed. If the standard PIO pattern is selected, no complete signal is output because a move command has not been executed yet. When the proximity type is selected, the actuator uses the same output method as the auto switch of an air cylinder.
(All ACON/PCON-CY controllers are shipped with the proximity type pre-selected.)
Q: Can we get a battery alarm output? (Warning state before discharged?)
A: Low battery warnings are output, as shown in the table below. For details, refer to the operation manual.
