Local control
Underneath the indicator lamps are keys for
local control.
[HAND START] is used if the VLT
frequency converter is to be
controlled via the control unit.
The VLT frequency converter will
start the motor, since a start
command is given by means of
[HAND START].
On the control terminals, the following
control signals will still be active when
[HAND START] is activated:
•
Hand start - Off stop - Auto start
• Safety Interlock
• Reset
• Coasting stop inverse

0 Hz, the motor will start and ramp up to this
frequency when [HAND START] is activated.
[OFF/STOP] is used for stopping the
connected motor. Can be selected
as Enable [1] or Disable [0] via
parameter 013. If the stop function is
activated, line 2 will flash.
[AUTO START] is used if the VLT
frequency converter is to be controlled
via the control terminals and/or serial
communication. When a start signal is
active on the control terminals and/or
the bus, the VLT frequency converter
will start.
NB!
An active HAND-OFF-AUTO signal via the
digital inputs will have higher priority than the
control keys [HAND START]-[AUTO START].

frequency converter after an alarm
(trip). Can be selected as Enable [1] or
Disable [0] via parameter 015 Reset
