1. Disconnect from the line power and wait until
the display turns off.
2a. Press [Status] - [Main Menu] - [OK] at the
same time while power-up for graphical LCP
(GLCP)
2b. Press [Menu] while power-up for LCP 101,

3. Release the keys after 5 s
4. The adjustable frequency drive is now
programmed according to default settings
This parameter initializes all except:

15-05 Over Volts
5.1.10 RS-485 Bus Connection
Both filter and adjustable frequency drive can be
connected to a controller (or master) together with other
loads using the RS-485 standard interface. Terminal 68 is
connected to the P signal (TX+, RX+), while terminal 69 is
connected to the N signal (TX-, RX-).
Always use parallel connections for the Low Harmonic
Drive to ensure that both filter and drive are connected.

Figure 5.16 Connection Example
To avoid potential equalizing currents in the shield, ground
the cable shield via terminal 61, which is connected to the
frame via an RC link.
Bus termination
Terminate the RS-485 bus by a resistor network at both
ends. If the adjustable frequency drive is the first or the
last device in the RS-485 loop, set the switch S801 on the
control card for ON.

5.1.11 How to Connect a PC to the
Adjustable Frequency Drive
To control or program the Low Harmonic Drive from a PC,
install the PC-based configuration tool MCT 10 Set-up
Software.
The PC is connected via a standard (host/device) USB cable
to both adjustable frequency drive and filter, or via the
RS-485 interface. How to connect a PC to the adjustable
frequency drive
NOTICE!
The USB connection is galvanically isolated from the
supply voltage (PELV) and other high-voltage terminals.
The USB connection is connected to ground protection
on the adjustable frequency drive. Use only an isolated
laptop as PC connection to the USB connector on the
adjustable frequency drive.
For control cable connections, see
