The ENABLE input must always be activated to enable the inverter operation regardless of the control mode.
If the ENABLE input is disabled, the inverter output voltage is set to zero, so the motor performs a cost to stop. If
the ENABLE command is active at power on, the inverter will not start until terminal 6 is opened and closed
again. This safety measure may be disabled through parameter C61 (IFD SW) or C53 (VTC SW). The ENABLE
command also unlocks PID regulator - if used regardless of the inverter operation - whether neither MDI3 nor
MDI4 are set as A/M (Automatic/Manual).
NOTE
When the ENABLE command is active, alarms A11 (Bypass Failure), A25 (Mains
Loss) (IFD SW only), A30 (DC OverVoltage) and A31 (DC UnderVoltage) are
enabled as well.

To enable the Start input, set the control modes via terminal board (factory setting). When the START input is
active, the main reference is enabled; otherwise, the main reference is set to zero. The output frequency (IFD
SW) or the speed motor (VTC SW) drops to zero with respect to the preset deceleration ramp. If C21 (IFD SW) or
C14 (VTC SW) is set to Kpd (command sent via keypad), the START input is disabled and its functionality is
performed by the inverter remotable keypad (see the COMMANDS MENU in Sinus K’s Programming
Instructions Manual). If the REV function ("reverse rotation") is active, the START input may be used only when the
REV input is inactive; if START and REV are enabled at a time, the main reference is set to zero.

If an alarm trips, the inverter stops, the motor performs a coast to stop and the display shows an alarm message
(see section 8 “DIAGNOSTICS”). Open the reset input for a while or press the RESET key to reset the alarm. This
happens only if the cause responsible for the alarm has disappeared and the display shows "Inverter OK". If
factory setting is used, enable and disable the ENABLE command to restart the inverter. If parameter C61 (IFD
SW) or C53 (VTC SW) is set to [YES], the inverter is reset
and
restarts. The reset terminal also allows resetting the
UP/DOWN commands; to do so, set parameter P25 "U/D RESET" to [YES].
NOTE
Factory setting does not reset alarms at power off. Alarms are stored and
displayed at next power on and the inverter is locked. To reset the inverter, turn it
off and set parameter C53 (IFD SW) or C48 (VTC SW) to [YES]
CAUTION
If an alarm trips, see the Diagnostics section and reset the equipment after
detecting the cause responsible for the alarm.
DANGER
Electrical shock hazard persists even when the inverter is locked on output
terminals (U, V, W) and on the terminals used for the connection of resistive
braking devices (+, -, B).
