Stop command from serial communication

•

Quick stop

•

DC brake

[Off]

stops the connected motor. The key can be

Enabled

[1] or

Disabled

[0] via par. 0-41

[Off] Key on LCP

.

If no external stop function is selected and the [Off] key is inactive, the motor can be stopped by disconnecting the line power supply.

[Auto on]

enables the adjustable frequency drive to be controlled via the control terminals and/or serial communication. When a start signal is applied to the control
terminals and/or the bus, the adjustable frequency drive will start. The key can be

Enabled

[1] or

Disabled

[0] via par. 0-42

[Auto on] Key on LCP

.

NOTE!

An active HAND-OFF-AUTO signal via the digital inputs has higher priority than the control keys [Hand on] [Auto on].

[Reset]

is used for resetting the adjustable frequency drive after an alarm (trip). The key can be

Enabled

[1] or

Disabled

5.1.3 RS-485 Bus Connection

One or more adjustable frequency drives can be connected to a controller
(or master) using the standard RS-485 interface. Terminal 68 is connec-
ted to the P signal (TX+, RX+), while terminal 69 is connected to the N
signal (TX-, RX-).

If more than one adjustable frequency drive is connected to a master,
use parallel connections.

Figure 5.6: Connection example.

In order to avoid potential equalizing currents in the screen, ground the cable screen via terminal 61, which is connected to the frame via an RC link.

Bus termination

The RS-485 bus must be terminated by a resistor network at both ends. If the drive is the first or the last device in the RS-485 loop, set the switch S801
on the control card to ON.
For more information, see the paragraph

Switches S201, S202, and S801

.

5.1.4 How to Connect a PC to the Adjustable Frequency Drive

To control or program the adjustable frequency drive from a PC, install the PC-based Configuration Tool MCT 10.
The PC is connected via a standard (host/device) USB cable, or via the RS-485 interface as shown in the VLT HVAC Drive

Design Guide, chapter How to

Install > Installation of misc. connections

.

NOTE!

The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals. The USB connection is
connected to protection ground on the adjustable frequency drive. Use only isolated laptop for PC connection to the USB connector on
the adjustable frequency drive.
