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.
Connector

Active filter card
MK101
1-8
Input from external current transducers, 5 amp
MK108
1-8
Input from external transducers, 1 amp
Power Card
FK100
01, 02, 03
Aux relay 1 NC/N0, used for temperature feedback
FK101
04, 05, 06
Aux relay 2 NO, used to set line power contactor
Control card
MK102
12, 13
24 V DC power supply to digital inputs and external transducers. The maximum output
current is 200 mA. Terminal 12 used for internal relay feedback.
18
Digital input for controlling the filter. R = 2 Kohm. Less than 5 V = logic 0 (open).
Greater than 10 V = logic 1 (closed). Wired and programmed for start/stop signal from
drive in the LHD.
20
Common for digital input. Wired and programmed for start/stop signal from drive in
the LHD.
19, 27, 29
Digital inputs for controlling the filter. 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.
32, 33
Digital input for controlling the filter. R = 2 Kohm. Less than 5 V = logic 0 (open).
Greater than 10 V = logic 1 (closed). Wired and programmed for feedback from line
power.
37
0–24 V DC input for safety stop (some units). Jumper to terminal 13.
MK101
39
Common for analog and digital outputs.
42
Analog and digital outputs for indicating values such as THD, current and power. The
analog signal is 0/4 to 20 mA at a maximum of 500
Ω
. The digital signal is 24 V DC at
a minimum of 500
Ω
.
50
10 V DC, 15 mA maximum analog supply voltage for potentiometer.
53, 54
Selectable for 0 to 10 V DC voltage input, R = 10 k
Ω
, or analog signals 0/4 to 20 mA
at a maximum of 200
Ω
. Used for reference or feedback signals.
55
Common for terminals 53 and 54.
MK103
61
RS-485 common.
68, 69
RS-485 interface and serial communication

Table 2.10 Control Terminals and Associated Parameter
Control terminals must be programmed. Each control terminal has specific functions it is capable of performing and
associated parameter. The setting selected in the parameter enables the function of the terminal.
