are typically written to EEPROM through the 1311 programmer interface (i.e.,
when a 1311 user changes a parameter setting using the 1311). They can be
used in the VCL code, but changing a P_User (or P_UserBit) value with VCL
will only change the variable value in RAM and will not change the value in
EEPROM. Thus, these variables are intended for creating and defining 1311
parameters only.
TYPE QUANTITY RANGE
RAM 120 variables User1 – User120
NVUser EEPROM 15 variables NVUser1 – NVUser15
Block EEPROM 38 blocks NVM3 – NVM40
(15 variables each)
Parameters EEPROM 100 variables and P_User1 – P_User100
20 variables of 8 bits P_UserBit1 – P_UserBit20
each (160 bits)
VCL can modify the 1311 control mode parameters in RAM by using
the VCL variable name for the 1311 parameter. For example,
Brake_Rate_SpdM = 3000 ;Change Brake Rate to 3.0sec
will change the RAM value of the speed control mode’s Brake Rate; the new
value will be used in determining the Controller Torque Command. However,
the value of the stored EE value of this parameter remains unchanged; when
the controller is turned off, the RAM value will be lost. The next time the
controller is powered back on, the “old” value of Brake Rate will be restored
from EE memory. VCL cannot write to the EE memory. The 1311 parameter
settings in EE memory can be changed by using the 1311 to change the values
in the program menus.
