IAI America SSEL - Manual (Page 5)

CAUTION
Optional System-Memory Backup Battery
The SSEL controller can be used with the optional system-memory backup battery.
Caution: When installing the system-memory backup battery, “Other parameter No. 20” must be set to
“2.”
Installing the system-memory backup battery will add the following functions to the controller:
x Save SEL global data
Data of global variables, flags and strings will be retained even after the main power is turned off.
x Save RAM position data
Position data changed by SEL programs will be retained even after the main power is turned off.
x Save an error list
An error list containing up to 100 most recent errors will be retained even after the main power is turned
off.
If you need any or all of the above functions, you must install the optional system-memory backup battery.
Using a Rotary Actuator under Rotation Specification
With a rotary actuator designated as a model supporting rotation specification, rotation operation or limit rotation
operation can be set using parameters.
For information on setting these parameters, refer to 2, “Utilization Examples of Axis-specific Parameters” in
Appendix “Parameter Utilization.”
x Axis operation type, rotational axis mode
x Perform rotation operation or short-cut control with a rotational axis
However, pay attention to the following point:
Rotation operation is not supported by rotational axes of absolute specification. This is because the infinite
stroke mode, or short-cut control in the index mode, cannot be set for these axes.
