If an error occurs while executing SAVE SERVO PARAMETER, the Error Flag
(word b, bit 12) or the Warning Flag (word b, bit 11) will turn ON, and the cor-
responding axis error (warning) code will be input in word b+4 of the Axis
Operating Input Memory Area. Check the error code and perform appropriate
troubleshooting.
With PCUs of version 1.2 or earlier, SAVE SERVO PARAMETER cannot be
executed if an axis error has occurred. SAVE SERVO PARAMETER will be
ignored if it is executed when an axis error has occurred.
With PCUs of version 1.3 or later, SAVE SERVO PARAMETER can be exe-
cuted even when an axis error has occurred. When the parameters are saved,
however, the Error Flag can no longer be used to determine if an error has
occurred during the save. It is thus necessary to save Servo Parameters after
resetting the error or, if parameters are saved when there is an axis error, then
steps must be taken to confirm that the parameters were saved correctly.
Two types of Servo Parameters are transferred to the Servo Drive: online
parameters with set values that are enabled immediately after they are writ-
ten, and offline parameters, which are not enabled just by writing them. To
enable set values for offline parameters in Servo Drive operations, save the
parameters to the non-volatile memory, and then cycle the Servo Drive power.
Alternatively, execute WRITE SERVO PARAMETER/SAVE SERVO PARAME-
TER and then execute the Servo Drive's DEVICE SETUP.
When DEVICE SETUP is executed, the Servo Drive enables all the Servo
Parameters that have been transferred to set the Servo Drive, and initializes
the present position and output signal status. DEVICE SETUP can be exe-
cuted in Servo unlock status. If DEVICE SETUP is executed while in Servo
lock status, a Multistart Error (axis error code: 3050) will occur and DEVICE
SETUP will not be executed.
DEVICE SETUP is executed from the CPU Unit using the DEVICE SETUP Bit
in the Axis Operating Output Memory Area. DEVICE SETUP can be executed
for different axes at the same time.
Execute DEVICE SETUP when the Busy Flag for the corresponding axis is
OFF. If DEVICE SETUP is executed while the axis's Busy Flag is ON, a Multi-
start Error (axis error code: 3050) will occur and DEVICE SETUP will not be
executed.
Device setup starts when the DEVICE SETUP Bit in the Axis Operating Out-
put Memory Area turns ON. When executing the DEVICE SETUP command,
make sure that the DEVICE SETUP Bit remains ON until the Busy Flag in the
Axis Operating Input Memory Area turns ON.
