4. Set the Servo Parameters and save them.
Set the Servo Parameters required to execute direct operation.
To set parameters permanently, execute SAVE SERVO PARAMETER
(writes to the non-volatile memory).
To enable changed offline parameters, turn ON the power to the Servo
Drive again or execute DEVICE SETUP.
For details, refer to
5-3 Transferring Servo Parameters .
5. Execute SERVO LOCK.
6. Set the data used for the jogging operation.
Set the jogging operation speed data in the speed command value of the
Axis Operating Output Memory Area.
7. Start the jogging operation.
When using the PCU for the first time or to change the Common Parameter
data, steps 1 and 2 must be performed. After executing SERVO LOCK,
WRITE SERVO PARAMETER can be executed to set the acceleration/decel-
eration used each time the jogging operation is performed.
Note When specifying the Servo Parameters for acceleration/deceleration every
time, make sure that the axis operation is stopped (Busy Flag = 0) while
changing the acceleration/deceleration constants using WRITE SERVO
PARAMETER. Do not change parameters during axis operation. Changing
parameters while the axis is operating may result in displaced positioning or
other malfunction.
10-2-3 PCU Data Settings for Jogging Operations
A simple explanation of the main parameters and data used to execute the
jogging operation is provided here. To execute jogging operations, apart from
the parameters explained here, the following parameters also need to be set
as basic settings for operating the PCU.
• External I/O Signal Allocations
Refer to 6-4 Standard Settings for Servo Drives Using MECHATROLINK .
• Command Unit
Refer to 7-2 Control Units .
The setting units for parameters and data depend on the specified com-
mand unit.
