Actual signals and parameters 187
Group 17: Override
Code Description Range Resolution Default S
1701
OVERRIDE SEL
-5…5 1 0
Selects the source of the override activation signal.
0 = NOT SEL – Override activation signal not selected.
1 = DI1 – Defines digital input DI1 as the override activation signal.
• This digital input must be activated for override activation signal.
2…5 = DI2…DI5 – Defines digital input DI2…DI5 as the override activation signal.
• See DI1 above.
-1 = DI1(INV) – Defines an inverted digital input DI1 as the override activation signal.
-2…-5 = DI2(INV)…DI5(INV) – Defines an inverted digital input DI2…DI5 as the
override activation signal.
• See DI1(INV) above.
1702 OVERRIDE FREQ -500 … 500 Hz 0.1 0.0
Defines a preset frequency for the override.
1704 OVERR PASS CODE 0…65535 1 0
Entering the correct override pass code unlocks parameter 1705 OVERRIDE for one
change.
• Enter the pass code always before changing the value of the parameter
1705 .
• The pass code is 358.
• The entry reverts back to zero automatically.
1705 OVERRIDE 0…2 1 0
Selects whether the override is enabled or disabled.
0 = OFF – Override disabled.
1 = ON – Override enabled.
• When enabled, the drive stores the values of all parameters into an override
parameter set (see parameter 9902 APPLIC MACRO ) and the parameters in
Group 17: Override will be write protected (except parameter 1704 OVERR PASS
CODE ). To change the other parameters in Group 17: Override , override has to
be disabled.
2 = LOAD – Loads the saved override set into use (as an active parameter set).
1706
OVERRIDE DIR
Selects the source of the override direction signal.
0 = FORWARD – Assigns forward as the override direction.
1 = DI1 – Defines digital input 1 as the override direction signal.
• Activating the digital input selects the forward direction.
• De-activating the digital input selects the reverse direction.
2…5 = DI2…DI5 – Defines digital input DI2…DI5 as the override direction signal.
See DI1 above.
7 = REVERSE – Assigns reverse as the override direction.
-1 = DI1(INV) – Defines an inverted digital input DI1 as the override direction signal.
• De-activating the digital input selects the forward direction.
• Activating the digital input selects the reverse direction.
-2…-5 = DI2(INV)…DI5(INV) – Defines an inverted digital input DI2…DI5 as the
override direction signal.
• See DI1(INV) above.
