182 Actual signals and parameters
1606
LOCAL LOCK
-5…8 1 0
Defines control for the use of the HAND mode. The HAND mode allows drive control
from the control panel.
• When LOCAL LOCK is active, the control panel cannot change to HAND mode.
0 = NOT SEL – Disables the lock. The control panel can select HAND and control the
drive.
Note: The OFF key always stops the drive, regardless of the parameter 1606 LOCAL
LOCK value. If LOCAL LOCK is active and the drive is in the AUTO mode when
the OFF key is pressed, the drive remains in the AUTO mode but coasts to stop
and shows alarm 2017 OFF BUTTON on the control panel display. (This alarm is
shown on the control panel only; it is not indicated by relay outputs.) Press the
AUTO key to restart the drive.
Note: If the drive is in the OFF or HAND mode and LOCAL LOCK is activated (eg,
from the control panel or through a digital input), control from the control panel is
still possible until the drive is set to the AUTO mode. It is not until then that LOCAL
LOCK becomes effective, disabling changing from the AUTO mode to the OFF or
HAND mode by pressing the OFF or HAND key.
1 = DI1 – Defines digital input 1 as the control for setting the local lock.
• Activating the digital input locks out local control.
• De-activating the digital input enable the HAND selection.
2…5 = DI2…DI5 – Defines digital input DI2…DI5 as the control for setting the local
lock.
• See DI1 above.
7 = ON – Sets the lock. The control panel cannot select HAND, and cannot control the
drive.
8 = COMM – Defines bit 14 of the Command word 1 as the control for setting the local
lock.
• Command word is supplied through fieldbus communication.
• Command word is parameter 0301 FB CMD WORD 1.
-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 HAND selection.
-2…-5 = DI2(INV)…DI5(INV) – Defines an inverted digital input DI2…DI5 as the
control for setting the local lock.
• See DI1(INV) above.
1607
PARAM. SAVE
0, 1 1 0
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 parameter 1602 PARAMETER LOCK = 2 (NOT SAVED), parameters altered from
the control panel are not saved. To save, you must use this parameter.
• If parameter 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.
