6.1.2 Drive Control TerminalsDefinitions of the drive terminals are summarized inTable 6.3. Illustration 6.2 shows the removable driveconnectors and terminals.• Connector 1 provides four digital inputs, twoselectable digital inputs or outputs, 24 V DCterminal supply voltage, and a common foroptional customer supplied 24 V DC voltage.• Serial communications use EIA-485 connector 2with terminal 68 (+) and 69 (-).• Connector 3 provides two analog inputs, oneanalog output, 10 V DC supply voltage, andcommons for the inputs and output.• A USB port, connector 4, is also available for usewith the MCT 10 Set-up Software available on theDanfoss website.• Also provided are two Form C relay outputs thatare in various locations depending upon the driveconfiguration and size.See the drive support materials for detailed instructions.1423130BA012.1161 68 6939 42 50 53 54 5512 13 18 19 27 29 32 33 20 37Illustration 6.2 Drive Control TerminalsTerminal No. Function01, 02, 03, 04, 05,06Form-C relay output. Useable for AC or DC voltage and resistive or inductive loads. See drive support materials fordetails on voltage and current ratings and relay location.12, 13 24 V DC digital supply voltage. Useable for digital inputs and external transducers. To use the 24 V DC for digitalinput common, program 5-00 Digital I/O Mode for PNP operation. Maximum output current is 200 mA total for all24 V loads.18, 19, 32, 33 Digital inputs. Selectable for NPN or PNP function in 5-00 Digital I/O Mode . Default is PNP.27, 29 Digital inputs or outputs. Programmable for either. 5-01 Terminal 27 Mode for terminal 27 and 5-02 Terminal 29Mode for 29 selects input/output function. Default setting is input.20 Common for digital inputs. To use for digital input common, program 5-00 Digital I/O Mode for NPN operation.39 Common for analog output.42 Analog output. Programmable for various functions in parameter group 6-5* Analog Output 42. The analog signal is 0to 20 mA or 4 to 20 mA at a maximum of 500 Ω.50 10 V DC 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 shieldtermination.68 (+), 69 (-) RS-485 interface. When the drive is connected to an RS-485 serial communication bus, a drive control card switch isprovided for termination resistance. ON for termination and OFF for no termination.
