Power I/O terminals
Terminal
Function Description
1L1, 3L2, 5L3 Mains Input 3ph input voltage.
2T1, 4T2, 6T3 Motor output Output terminals to 3ph AC motor
TBA1, TBA2 Input Control Voltage 110/120V AC, +10%, -15%
Digital Inputs
Terminal
Function Description
57 Common for digital inputs This is a common terminal for the digital input terminals specified below.
1 Run Run order. Command signal may be provided by one NO dry momentary contact to terminals 1 and 57.
2 Stop Stop order. Command signal may be provided by one NC dry momentary contact to terminals 2 and 57.
NOTE: Run/Stop permanent command is allowed linking 1-57 and using one dry NO contact to 2-57
terminals.
3 Programmable input I3 These two inputs are programmable. Can be assigned to the following internal functions:
4 Programmable input I4
-soft stop -linear ramp
-pump control -dual ramp selection
-kick start -local / remote control
Command signal should be provided by one NC dry contact to terminals 57-3 or terminals 57-4.
By switching this contact ON / OFF it is possible to enable or disable the assigned function.
Digital Outputs
Terminal
Function Description
11, 12, 14 Programmable relay 1r 11-12 = NC, 11-14 = N.O. dry contacts. This relay can be assigned to several internal output functions (p. 3-5).
As default assigned to function RUN
23, 24 Fixed relay 2r 23-24 = N.O. dry contact. This relay is assigned to function EOR for bypass contactor control
33, 34 Programmable relay 3r 33-34 = N.O. dry contact. This relay can be assigned to several internal output functions (page 3-5).
Common for all relay output contacts Maximum usage voltage: 380VAC (B300-UL)
Thermal current: 8A
AC-15 use: 220V / 3A, 380V / 1A
DC-15 use: 30V max/ 3.5A
Analog I/O
Terminal
Function Description
8 Analog input common (-) This is a common terminal for the analog input terminal number 7 and analog output terminal number 9.
7 TG feedback input (+) 0-5V analog input for speed feedback. It should be provided by a DC tacho-generator coupled to the motor.
This speed feedback signal is required when the "linear ramp" function is used.
9 Current output (+) 0-10V DC analog Output for current measurement purpose. (1 x Ir = 2V DC output)
Load Impedance 10K Ω or higher.
Motor thermistor terminals
Terminal
Function Description
5 , 6 Motor thermistor input This input allows a motor thermistor with a response value from 2.8 to 3.2K
Ω
, and a reset value from 0.75 to
1K
Ω
to control motor temperature.
When the motor thermistor is not used, a link must be used between terminals 5-6.
Communications
Terminal
Function Description
SG, TD, RD Gr, Tx, Rx data RS232C, 3 wires, half duplex. Maximum cable length 3 meters (10 feet)
Asynchronous data transmission, 9600 Bauds, 1 bit start, 8 bits data, 2 bits stop, no parity.
