*1. Timing of detection
1) Level detection: activated when the bit is set or cleared.
2) Edge detection: activated at OFF-to-ON transition (b1: ON-to-OFF transition).
*2. BFM #619 (b1) is not available.
POINT
1) Changing positioning parameters
When the 20SSC-H is powered ON, operation starts with the positioning parameters in the flash memory.
When the buffer memory positioning parameters are changed via FX Configurator-FP or a sequence
program, it is necessary to activate the positioning parameters enable command. Without activating the
command, changes will not be reflected in actual operation. Changing the positioning parameters enable
command must be done during stop in order for the changes to become valid.
2) Transferring servo parameters
a) The following servo parameters are transferred to the servo amplifier when activating the servo
parameter transfer command.
- Auto tuning mode
- Auto tuning response
- Feed forward gain
- Ratio of load inertia moment to servo motor inertia moment
- Model loop gain
b) During positioning operations, the servo parameter transfer command is ignored.
c) "Transferring servo parameters" in the status information is ON during the transfer.

Description
Set this to cancel the standby status for the remaining travel
after the STOP command.
→For details on the stop command, refer to Section 7.4
Turns ON for 100ms or more, and resets the 20SSC-H
system when detecting this bit's falling edge.
-
Set this to enable positioning parameters in the buffer
memories.
Whenever you make a change to positioning parameters, this
bit must be set before starting operation.
-
OFF : Relative positioning by the specified travel distance
ON : Absolute positioning by the specified address
-
Set this to turn the servo OFF.
→For details on the servo ON/OFF state, refer to
0: servo ON
1: servo OFF
Set this to transfer servo parameters in the buffer memories to
the servo amplifier.
Changes the gain of the amplifier from the 20SSC-H.
For details on changing gain, refer to the manual shown
below.
→MR-J3- B Servo Amplifier Instruction Manual
Set this to disable update of servo parameters even when the
servo amplifier gives servo parameter update request.
→For details on the servo parameter update stop
command, refer to Subsection 6.3.5.
