Electrical Control Terminals - Danfoss VLT 6000 Manual

Electrical Control Terminals

In most cases, the VLT 6000 will have electrical
control connections (see Figure 4) already
connected at equipment installation. The functional
description of the drive's electrical control terminals
in Table 5 are provided primarily for system
modification and expansion. Two examples of typical
Table 5 Electrical Control Terminals Functional Description
Number
01, 02, 03 Form C relay output. Maximum 240 VAC, 2 A. Minimum 24 VDC, 10 mA or 24 VAC, 100 mA.
(Terminal group 01, 02, and 03 is placed in various locations on the power side of the drive,
depending upon the model type.)
04, 05 30 VAC, 42.5 VDC, 1 Amp relay outputs can be used for indicating status and warnings.
12, 13 Voltage supply to digital inputs and external transducers. For the 24 VDC to be used for digital
inputs, switch 4 on the control card must be closed (position on). The maximum output current
is 200 mA.
16 - 33 Digital inputs. R = 2 kohm
<5 V = logical 0
>10 V = logical 1
16 - 33 30 VAC, 42.5 VDC, 1 A relay output can be used for indicating status and warnings.
20 Voltage supply to digital inputs and external transducers. For the 24 VDC to be used for digital
inputs, switch 4 on the control card must be closed (position on). The maximum output current
is 200 mA.
39 Digital inputs. R = 2 kohm. <5 V = logical 0 , >10 V = logical 1
42, 45 Analog and digital outputs for indicating frequency, reference, current and torque. The analog
signal is 0 to 20 mA, or 4 to 20 mA at a maximum of 500 ?. The digital signal is 24 VDC at a
minimum of 600 ?.
50 10 VDC, 17 mA maximum analog supply voltage to potentiometer and thermistor.
53, 54 0 to 10 VDC voltage input, R = 10 ?.
55 Common for analog inputs. This common is isolated from the common of all other power
supplies. If, for example, the drive s 24 VDC power supply is used to power an external
transducer which provides an analog input signal, terminal 55 must be wired to terminal 39.
60 0 to 20 mA or 4 to 20 mA, analog current input, R = 188 ? .
61 Shield for serial communication.
68, 69 RS-485 interface and serial communication. When the drive is connected to an R -485 serial
communication bus, DIP switches 2 and 3 must be closed on the first and the last device in the
serial connection. On the remaining drives, switches 2 and 3 must be open. The factory setting
is closed (position on).

serial interface control connections are
demonstrated in Figures 5 and 6. Many of these
terminals have multiple functions that are
determined by drive parameter settings. See the
VLT 6000 Operating Instructions for detailed
information.
