Drive Control Terminals; Drive Control Terminal Functions - Danfoss VLT Option Panel Instruction Manual

Drive Control Terminals

Definitions of the drive terminals are summarized in
Table 6-2. Figure 6-2 shows the removable drive
connectors and terminals.
• Connector 1 provides four digital inputs, two
selectable digital inputs or outputs, 24 VDC
terminal supply voltage, and a common for
optional customer supplied 24 VDC voltage.
• Serial communications use EIA-485
connector 2 with terminal 68 (+) and 69 (-).
• Connector 3 provides two analog inputs, one
analog output, 10 VDC supply voltage, and
commons for the inputs and output.
• A USB port, connector 4, is also available for
use with the MCT-10 programming software
available on the Danfoss website.
• Also provided are two Form C relay outputs
that are in various locations depending upon
the drive configuration and size.
See the drive support materials for detailed
instructions.

Terminal No.
01, 02, 03 Form-C relay output. Useable for AC or DC voltage and
04, 05, 06 resistive or inductive loads. See drive support materials for
details on voltage and current ratings and relay location.
12, 13 24 VDC digital supply voltage. Useable for digital inputs and
external transducers. To use the 24 VDC for digital input
common, program parameter 5-00 for PNP operation.
Maximum output current is 200 mA total for all 24V loads.
18, 19, 32, 33 Digital inputs. Selectable for NPN or PNP function in
parameter 5-00. Default is PNP.
Digital inputs or outputs. Programmable for either. Parameter
27, 29
5-01 for terminal 27 and 5-02 for 29 selects input/output
function. Default setting is input.
Common for digital inputs. To use for digital input common,
20
program parameter 5-00 for NPN operation.
39 Common for analog output.
42 Analog output. Programmable for various functions in
parameter 6-5x. The analog signal is 0 to 20 mA or 4 to 20 mA
at a maximum of 500 Ω.
50 10 VDC analog supply voltage. 15 mA maximum commonly
used for a potentiometer or thermistor.
53, 54 Analog input. Selectable for voltage (0-10 V) or current (0- or
4-20 mA). Closed is for current and open is for voltage.
Switches are located on the drive control card behind the
removable LCP. See drive support materials for details.
55 Common for analog inputs.
61 Common for serial communication. Do not use to terminate
shields. See drive support materials for proper shield
termination.
RS-485 interface. When the drive is connected to an RS-485
68 (+), 69 (-)
serial communication bus, a drive control card switch is
provided for termination resistance. ON for termination and
OFF for no termination. See drive support materials for details.
