2.7 Control Terminal Functions
The following describes the functions of the control terminals. Many of these terminals have multiple functions determined by parameter settings. Some options
provide additional terminals. See Illustration 2-2.
Terminal No.
Function
01, 02, 03 and 04, 05, 06
Two Form C output relays. Maximum 240 VAC, 2 A. Minimum 24 VDC, 10 mA or 24 VAC, 100 mA. Can be used for indicating
status and warnings. Physically located on the power card.
12, 13
24 VDC power supply to digital inputs and external transducers. The maximum output current is 200 mA.
18, 19, 27, 29, 32, 33
Digital inputs for controlling the frequency converter. R = 2 kohm. Less than 5 V = logic 0 (open). Greater than 10 V = logic
1 (closed). Terminals 27 and 29 are programmable as digital/pulse outputs.
20
Common for digital inputs.
37
0–24 VDC input for safety stop (some units).
39
Common for analog and digital outputs.
42
Analog and digital outputs for indicating values such as frequency, reference, current and torque. The analog signal is
0/4 to 20 mA at a maximum of 500 Ω. The digital signal is 24 VDC at a minimum of 500 Ω.
50
10 VDC, 15 mA maximum analog supply voltage for potentiometer or thermistor.
53, 54
Selectable for 0 to 10 VDC voltage input, R = 10 kΩ, or analog signals 0/4 to 20 mA at a maximum of 200
Ω. Used for
reference or feedback signals. A thermistor can be connected here.
55
Common for terminals 53 and 54.
61
RS-485 common.
68, 69
RS 485 interface and serial communication.

Table 2.2: Control Terminals and Associated Parameter
Control terminals must be programmed. Each terminal has specific functions it is capable of performing and a numbered parameter associated with it. The setting
selected in the parameter enables the function of the terminal. See the Drives Series Operating Instructions for details.
