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
•
Reversing
•
Setup select lsb - Setup select msb
•
Jog
•
Run permissive
•
Lock for data change
•
Stop command from serial
communication
NB!
If parameter 201
Output frequency low limit f
MIN
is set to an output frequency greater than 0
Hz, the motor will start and ramp up to this frequency
when [HAND START] is activated.
[OFF/STOP] is used for stopping the con-
nected 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].
[RESET] is used for resetting the VLT
frequency converter after an alarm (trip).
Can be selected as
Enable
[1] or
Disable
[0]
via parameter 015
Reset on LCP.

Display mode
In normal operation, any 4 different operating variables
can be indicated continuously: 1.1 and 1.2 and 1.3
and 2. The present operating status or alarms and
warnings that have arisen are shown in line 2 in the
form of a number. In the case of alarms, the alarm in
question will be shown in lines 3 and 4, accompanied
by an explanatory note. Warnings will flash in line 2,
with an explanatory note in line 1. In addition, the
display shows the active Setup.
The arrow indicates the direction of rotation; here the
VLT frequency converter has an active reversing
signal. The arrow body disappears if a stop command
is given or if the output frequency falls below 0.01 Hz.
The bottom line gives the status of the VLT frequency
converter. See next page.
The scroll list on the next page gives the operating
data that can be shown for variable 2 in display mode.
Changes are made via the [+/-] keys.
