Control unit
On the front of the variable frequency drive
there is a control panel.
The control panel is divided into five functional groups:
1. Status LED
2. Keys for changing parameters and shifting
display function.
3. LEDs.
4. Keys for local operation.
All displays of data are in the form of a six-digit LED
display capable of showing one item of operating
data continuously during normal operation. As a
supplement to the display, there are three LEDs
for indication of electrical connection (ON), warning
(WARNING) and alarm (ALARM). Most of the
variable frequency drive
’
s parameter Setups can be
changed immediately via the control panel, unless
this function has been programmed as
Locked
[1]
via parameter 018
Lock for data changes
.

Control keys
[QUICK MENU]
allows access to the parameters
used for the Quick menu.
The[QUICK MENU] key is also used if a change to a
parameter value is not to be implemented.

NOTE
If the [STOP/RESET] key is set at
Not active
[0] in parameter 014
Local stop/reset,
and
there is no stop command via the digital
inputs or serial communication, the motor can
only be stopped by disconnecting the electrical
voltage to the variable frequency drive.
[START]
is used for starting the variable frequency
drive. It is always active, but the [START] key
cannot override a stop command.

Manual initialization
To manually initialize the adjustable frequency drive to
factory default settings, first disconnect AC line voltage.
Hold the [QUICK MENU] and [+] and [CHANGE DATA]
