ACS550 User’s Manual 87
Start-Up
1605 USER PAR SET CHG
Defines control for changing the user parameter set.
• See parameter 9902 (
APPLIC MACRO). 
• The drive must be stopped to change User Parameter Sets.
• During a change, the drive will not start.
Note: Always save the User Parameter Set after changing any parameter settings, or performing a motor 
identification. 
• Whenever the power is cycled, or parameter 9902 (
APPLIC MACRO) is changed, the drive loads the last settings 
saved. Any unsaved changes to a user parameter set are lost.
Note: The value of this parameter (1605) is not included in the User Parameter Sets, and does not change if User 
Parameter Sets change. 
Note: You can use a relay output to supervise the selection of User Parameter Set 2. 
• See parameter 1401.
0 = 
NOT SEL – Defines the control panel (using parameter 9902) as the only control for changing User Parameter 
Sets.
1 = 
DI1 – Defines digital input DI1 as a control for changing User Parameter Sets.
• The drive loads User Parameter Set 1 on the falling edge of the digital input.
• The drive loads User Parameter Set 2 on the rising edge of the digital input.
• The User Parameter Set changes only when the drive is stopped.
2…6 = DI2…DI6 – Defines digital input DI2…DI6 as a control for changing User Parameter Sets.
•See 
DI1 above.
-1 = 
DI1(INV) – Defines an inverted digital input DI1 as a control for changing User Parameter Sets.
• The drive loads User Parameter Set 1 on the rising edge of the digital input.
• The drive loads User Parameter Set 2 on the falling edge of the digital input.
• The User Parameter Set changes only when the drive is stopped.
-2…-6 = DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as a control for changing User Parameter Sets.
•See 
DI1(INV) above.
1606 LOCAL LOCK
Defines control for the use of the LOC mode. The LOC mode allows drive control from the control panel.
• When 
LOCAL LOCK is active, the control panel cannot change to LOC mode.
0 = 
NOT SEL – Disables the lock. The control panel can select LOC and control the drive.
1 = 
DI1 – Defines digital input DI1 as the control for setting the local lock.
• Activating the digital input locks out local control.
• De-activating the digital input enable the LOC selection.
2…6 = 
DI2…DI6 – Defines digital input DI2…DI6 as the control for setting the local lock.
•See 
DI1 above.
7 = 
ON – Sets the lock. The control panel cannot select LOC, and cannot control the drive.
8 = 
COMM – Defines bit 14 of the Command Word 1 as the control for setting the local lock.
• The Command Word is supplied through fieldbus communication.
• The Command Word is 0301.
-1 = 
DI1(INV) – Defines an inverted digital input DI1 as the control for setting the local lock.
• De-activating the digital input locks out local control.
• Activating the digital input enable the LOC selection.
-2…-6 = 
DI2(INV)…DI6(INV) – Defines an inverted digital input DI2…DI6 as the control for setting the local lock.
•See 
DI1(INV) above.
1607 PARAM. SAVE
Saves all altered parameters to permanent memory. 
• Parameters altered through a fieldbus are not automatically saved to permanent memory. To save, you must use 
this parameter.
• If 1602 
PARAMETER LOCK = 2 (NOT SAVED), parameters altered from the control panel are not saved. To save, you 
must use this parameter.
• If 1602 
PARAMETER LOCK = 1 (OPEN), parameters altered from the control panel are stored immediately to 
permanent memory. 
0 = 
DONE – Value changes automatically when all parameters are saved.
1 = 
SAVE – Saves altered parameters to permanent memory.
