POINT
1) When executing the system reset command
Write the model code (K5220) to the "control command enable/disable (BFM #522)" before executing the
system reset command.
2) 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 when both the Positioning Operation STOP and STOP command state is OFF in
order for the changes to become valid.
3) Transferring servo parameters
a) The following servo parameters are transferred to the servo amplifier when activating the servo
parameter transfer command.
The table below shows transferrable servo parameters depending on the setting of the auto tuning
mode.
Auto tuning mode
Auto tuning response
Feed forward gain
Ratio of load inertia moment to servo motor inertia moment
Model loop gain
Position loop gain
Speed loop gain
Speed integral compensation
Speed differential compensation
*1. These parameters are automatically adjusted in the interpolation mode.
*2. These parameters are automatically adjusted in auto tuning mode 1.
*3. These parameters are automatically adjusted in auto tuning mode 2.
b) During positioning operations or when the STOP command state is ON, the servo parameter transfer
command is ignored.
c) "Transferring servo parameters" in the status information is ON during the transfer.
