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