3.2.3  STAP – Store Axis Parameter 

 

Description: 

Axis parameters are located in RAM memory, so modifications are lost at power down. 

This instruction enables permanent storing of the previously with SAP altered parameter. All 
parameters alterable with SAP – Set Axis Parameter can be stored, except Type 1 – Set Actual 
Position and Type 160 - Re-Initialization of Sine Commutation (refer to 3.2.1). 

 
Internal function:

 The specified parameter is copied from its RAM location the configuration 

EEPROM. 

 
Related commands:

 SAP, GAP 

 
Mnemonic:

 STAP <parameter number> 

 
Binary representation: 

INSTRUCTION NO. 

TYPE MOT/BANK  VALUE
