NOTE
If software timers are enabled for digital inputs, the timer for the MDI2 input delays the
signal enabling. The ENABLE signal is always instantly disabled (for the ENABLE
function, Toff in MDI2 is ignored).
NOTE
The activation of the ENABLE command enables the alarms controlling the configuration
consistency of certain parameters.
NOTE
When the ENABLE function is active, C parameters cannot be changed (factory-setting).
If P003 Condition required for changing C parameters = Standby+Fluxing, the parameters
may be changed even if the drive is enabled but the motor is not running.
NOTE
When the ENABLE function is active for VTC and FOC controls, the motor is fluxed by the
drive. Motor fluxing is allowed only if the START contact is shut down and C184 = Yes.
NOTE
If set accordingly, safety parameter C181 prevents the drive from starting if the ENABLE
function is already active when the drive is powered on.
37.1.3. RESET (TERMINAL 16:MDI3)
The RESET function is assigned to input terminal MDI3. It resets the alarms to unlock the drive operation. It cannot
be set to other terminals, whereas the same terminal may be assigned to different functions. To disable the reset
function from terminal MDI3, set C154 = Yes.
If a protection trips, the drive locks, the motor starts idling (the motor idles and stops due to friction or the
mechanical load) and an alarm message is displayed (see also the AUTORESET MENU and the ALARMS AND
WARNINGS section).
Reset procedure
To unlock the drive, activate the RESET input for an instant, or press the RESET key from the keypad. When the
drive unlocks and the cause responsible for the alarm has disappeared, “Inverter ok” comes up on the screen,
otherwise, the alarm persists and cannot be reset.
If set up accordingly, safety parameter C181 permits to deactivate and reactivate the ENABLE function to restart the
drive once the cause responsible for the alarm has disappeared.
NOTE
Factory setting does not reset alarms at power off. Alarms are stored and displayed at
next power
on and the drive is locked. A manual reset is then required to unlock the drive
(see the AUTORESET MENU).
CAUTION
If an alarm trips, see the ALARMS AND WARNINGS
section
after detecting the cause responsible for the alarm.
DANGER!!!
Electrical shock hazard exists on output terminals (U, V, W) and resistive braking module
terminals (+, –, B) even when the drive is disabled.
NOTE
Set C154 = Yes
to remove the reset function from MDI3. After that, only one different
function can be allocated to MDI3 even when multiprogramming is active (see parameter
C182).
