180 Actual signals and parameters
1602
PARAMETER LOCK
0…2 1 1
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 PASS
CODE.
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
0…65535 1 0
Entering the correct pass code allows you to change the parameter lock.
• See parameter 1602 PARAMETER LOCK above.
• Code 358 allows you to change the value of the parameter 1602 PARAMETER
LOCK once.
This entry reverts back to 0 automatically.
1604
FAULT RESET SEL
-5…7 1 0
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…5 = DI2…DI5 – Defines digital input DI2…DI5 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 fieldbus 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 FB CMD WORD 1) resets the
drive.
-1 = DI1(INV) – Defines an inverted digital input 1 as a fault reset source.
• De-activating the digital input resets the drive.
-2…-5 = DI2(INV)…DI5(INV) – Defines an inverted digital input DI2…DI5 as a fault
reset source.
• See DI1(INV) above.
