Terminal Function
No.
01, 02, 03, Form-C relay output. Useable for AC or DC voltage and resistive or inductive loads. See drive
04, 05, 06 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, Digital inputs. Selectable for NPN or PNP function in parameter 5-00. Default is PNP.
33
27, 29 Digital inputs or outputs. Programmable for either. Parameter 5-01 for terminal 27 and 5-02 for
29 selects input/output function. Default setting is input.
20 Common for digital inputs. To use for digital input common, 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 ther-
mistor.
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
keypad. 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 mate-
rials for proper shield termination.
68 (+), 69 (-) RS-485 interface. When the drive is connected to an RS-485 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.
