PRM46: Servo status output
This parameter selects whether to output the axis servo status as a general-purpose output.
When this parameter is set to 1, DO3 turns on and off along with servo on/off.
Input range: 0 or 1
Meaning: 0: Does not output the servo status.
1: Outputs the servo status.
Default value: 0
* When this parameter is set to 1, DO3 is not affected by program reset (in other words,
DO3 does not turn off even when the program is reset).
PRM47: Communication parameter setting
This sets communication parameters used for data transmission through RS-232C. For
more details, see "11-1 Communication Parameter Specifications".
Default value: 0
PRM48: Pre-operation action selection
This parameter checks whether return-to-origin has been performed or resets the program
before running automatic operation or step operation.
When set to 0 or 2, an error (return-to-origin incomplete) is issued if return-to-origin has
not been performed and automatic operation and step operation are not accepted.
When set to 1 or 3, the program runs even when return-to-origin has not been performed.
However, an error (return-to-origin incomplete) is issued when a movement command
(MOVA, etc.) is executed if return-to-origin is still incomplete. To avoid this, perform
return-to-origin in advance or insert the ORGN command into the program.
Input range: 0 to 3
Meaning: 0: Checks whether return-to-origin has been performed.
1: Nothing is executed.
2: Resets the program after checking return-to-origin.
3: Resets the program.
Default value: 1
* When set to 2 or 3, the program is reset only during automatic operation. (The program
is not reset during step operation.)
PRM49: Controller version 1
This parameter reads out the version information (1) on the control software in the con-
troller.
This is a read-only parameter.
PRM50: Deceleration
Use this parameter to reduce only the deceleration.
When this parameter is left set to the default value (100), the deceleration is the same as
the acceleration. If vibration occurs during positioning, then set this parameter to a smaller
value to reduce only the deceleration.
This parameter value can be changed in 1% steps, with 100% equal to the value deter-
mined by PRM4.
Input range: 1 to 100 (%)
Default value: 100
