Group 16: SYSTEM CONTROLS<br />
This group defines a variety of system level locks, resets and enables.<br />
Group 16: System Controls<br />
Code Description Range Resolution Default S<br />
1601 RUN ENABLE -6…7 1 0 (NOT SEL) <br />
Selects the source of the run enable signal.<br />
0 = NOT SEL – Allows the drive to start without an external run enable signal.<br />
1 = DI1 – Defines digital input DI1 as the run enable signal.<br />
• This digital input must be activated for run enable.<br />
• If the voltage drops and de-activates this digital input, the drive will coast to stop and not start until the run enable<br />
signal resumes.<br />
2…6 = DI2…DI6 – Defines digital input DI2…DI6 as the run enable signal.<br />
•See DI1 above.<br />
7 = COMM – Assigns the fieldbus Command Word as the source for the run enable signal.<br />
• Bit 6 of the Command Word 1 (parameter 0301) activates the run disable signal.<br />
• See fieldbus user’s manual for detailed instructions.<br />
-1 = DI1(INV) – Defines an inverted digital input DI1 as the run enable signal.<br />
• This digital input must be de-activated for run enable.<br />
• If this digital input activates, the drive will coast to stop and not start until the run enable signal resumes.<br />
-2…-6 = DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the run enable signal.<br />
•See DI1(INV) above.<br />
1602 PARAMETER LOCK 0…2 1 1 (OPEN)<br />
Determines if the control panel can change parameter values.<br />
• This lock does not limit parameter changes made by macros.<br />
• This lock does not limit parameter changes written by fieldbus inputs.<br />
• This parameter value can be changed only if the correct pass code is entered. See parameter 1603 PASS CODE.<br />
0 = LOCKED – You cannot use the control panel to change parameter values.<br />
• The lock can be opened by entering the valid pass code to parameter 1603.<br />
1 = OPEN – You can use the control panel to change parameter values.<br />
2 = NOT SAVED – You can use the control panel to change parameter values, but they are not stored in permanent<br />
memory.<br />
• Set parameter 1607 PARAM SAVE to 1 (SAVE...) to store changed parameter values to memory.<br />
1603 PASS CODE 0…65535 1 0<br />
Entering the correct pass code allows you to change the parameter lock.<br />
• See parameter 1602 above.<br />
• The code 358 allows you to change the value of the parameter 1602 once.<br />
• This entry reverts back to 0 automatically.<br />
1604 FAULT RESET SEL -6…8 1 0 (KEYPAD)<br />
Selects the source for the fault reset signal. The signal resets the drive after a fault trip if the cause of the fault no<br />
longer exists.<br />
0 = KEYPAD – Defines the control panel as the only fault reset source.<br />
• Fault reset is always possible with control panel.<br />
1 = DI1 – Defines digital input DI1 as a fault reset source.<br />
• Activating the digital input resets the drive.<br />
2…6 = DI2…DI6 – Defines digital input DI2…DI6 as a fault reset source.<br />
•See DI1 above.<br />
7 = START/STOP – Defines the Stop command as a fault reset source.<br />
• Do not use this option when fieldbus communication provides the start, stop and direction commands.<br />
8 = COMM – Defines the fieldbus as a fault reset source.<br />
• The Command Word is supplied through fieldbus communication.<br />
• The bit 4 of the Command Word 1 (parameter 0301) resets the drive.<br />
-1 = DI1(INV) – Defines an inverted digital input DI1 as a fault reset source.<br />
• De-activating the digital input resets the drive.<br />
-2…-6 = DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as a fault reset source.<br />
•See DI1(INV) above.<br />
