Amp Parameter R/W Function - Panasonic FP? Positioning Unit RTEX Technical Manual

13.10 AMP Parameter R/W Function

The positioning unit RTEX can execute the following operations for AMP via network (Realtime Express).
Reading AMP parameters
-
Writing AMP parameters
-
Saving AMP parameters (EEPROM write)
-
Resetting AMP (Restart)
-
For performing the AMP control with the positioning unit RTEX, use the AMP parameter control area
(Shared memory: Bank 52H, Address from 000H) after changing the AMP control mode (System
operation setting area: Shared memory: Bank 00H, Address 384H) to 1H (AMP control enable).
Each operation of AMP control can be executed only when the target axis stops.
If the operation is executed when the axis is activated, it will end because the request cannot be
executed.
Reading parameters, however, can be executed during operations other than home return.
The procedure of each operation for AMP is described below.
13.10.1 Reading AMP Parameters
[With A4N]
1. Change the AMP control mode to "1 (AMP control enable)".
2. AMP parameter control area
Set the axis number (AMP ID No.) to be read to the AMP ID number.
Set the parameter number to be read to the individual parameter number.
Set the control flag to "2H (Read request)".
3. The positioning unit RTEX reads parameters of the AMP and stores the parameter values in the A4N
parameter data of the AMP parameter control area.
4. Confirm the AMP parameter control area status is 2H (Normal end).
5. Change the AMP control mode to "0 (AMP control disable)" after reading parameter data.
[With A6N / A5N]
1. Change the AMP control mode to "1 (AMP control enable)".
2. AMP parameter control area
Set the axis number (AMP ID No.) to be read to AMP ID number.
Set the parameter classification to be read to the A6N/A5N parameter classification.
Set the parameter number to be read to the individual parameter number.
Set the control flag to "2H (Read request)".
3. The positioning unit RTEX reads parameters of the AMP and stores the parameter values in the
A6N/A5N parameter data of the AMP parameter control area.
Note that the A6N/A5N parameter is double word data.
4. Confirm the AMP parameter control area status is 2H (Normal end).
5. Change the AMP control mode to "0 (AMP control disable)" after reading parameter data.
