5 Controls and Options Installation
5.1 Control Wiring
UNINTENDED START
When the drive is connected to the AC mains, DC supply, or load sharing, the motor may start at any time, causing risk of
death, serious injury, and equipment or property damage. The motor may start by activation of an external switch, a fieldbus
command, an input reference signal from the LCP or LOP, via remote operation using MCT 10 setup software, or after a cleared
fault condition.
Press [Off] on the LCP before programming parameters.
l
Disconnect the drive from the mains whenever personal safety considerations make it necessary to avoid unintended motor
l
start.
Check that the drive, motor, and any driven equipment are in operational readiness.
l
It is recommended that control wiring is rated for 600 V.
l
Isolate control wiring from high-power components in the drive.
l
If the drive is connected to a thermistor, for PELV isolation, ensure that control wiring is reinforced/double insulated.

5.2 Terminal Functions
Table 9: Terminal Functions
Terminal number Functions
01, 02, 03 Relay 1 output. Usable for AC or DC voltage and resistive or inductive loads.
04, 05, 06 Relay 2 output. Usable for AC or DC voltage and resistive or inductive loads.
12, 13 24 V DC digital supply voltage. Useable for digital inputs and external transducers. To use the 24 V DC for digital
input common, program parameter 5-00 Digital I/O Mode for PNP operation.
18, 19, 32, 33 Digital inputs. Selectable for NPN or PNP function in parameter 5-00 Digital I/O Mode. The default is PNP.
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 backup supply. Optional.
36 External +24 V control backup supply. Optional.
37 Safe Stop.
20 Common for digital inputs. To use for digital input common program 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
55 Common for analog inputs.
61 Common for serial communication (RS485 interface). See
