Operating Guide
Terminal Functions
Number
27, 29
Digital inputs or outputs. Program parameter 5-01 Terminal 27 Mode for terminal 27 and parameter 5-02 Terminal
29 Mode for terminal 29 for selecting the input/output functions. Default setting is input.
35 Common (-) for external 24 V control back-up supply. Optional.
36 External + 24 V control back up supply. Optional.
37 Safe Stop.
20
Common for digital inputs. To use for digital input common, programme parameter 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 1. The analog signal
is 0–20 mA or 4–20 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 to ±10 V) or current (0 or 4 to ± 20 mA). Closed is for current and open is
for voltage. Switches are located on the drive control card.
See 4.10.6 DIP
55 Common for analog inputs.
61 Common for serial communication (RS485 interface).
See 4.3 Grounding.
68 (+), 69 (-) RS485 interface. When the drive is connected to an RS485 serial communication bus, a switch on the control
card is provided for termination resistance. Set the switch to ON for termination and OFF for no termination.
62 RxD/TxD –P (red cable) for PROFIBUS. See dedicated literature for VLT® PROFIBUS DP V1 MCA 101) for details.
63 RxD/TxD –N (green cable) for PROFIBUS.
66 0 V for PROFIBUS.
67 +5 V for PROFIBUS.
B01-B12 B-option. See dedicated literature for details.
