ABB EC Titanium Series User Manual

Control Modes 9-4MN448
9.2.2 Terminal Control Mode 3-Wire Control Start / Stop with Forward / Reverse
Terminal Control Mode (1103 = 0), Digital Input Function Select (9902 = 11)
This is the digital input conguration when the drive is controlled using momentary push-buttons. It provides a general
purpose I/O setup with a momentary input for start, forward / reverse, stop interlock and an analog speed reference.
9902 = 11 3-Wire Forward Reverse
A momentary input on terminal 2 will start the drive
in the forward direction with a closed input on
terminal 3.
A momentary open input to I/O terminal 3 will stop
the drive as specied in 2101 (Stop Mode).
A momentary input on terminal 4 will reverse the
drive direction.
9.2.3 Terminal Control Mode Motor Thermistor Trip
Terminal Control Mode (1103 = 0), Digital Input Function Select (9902 = 3)
This is the digital input conguration when an externally motor thermistor is to be used as an overload trip input to the drive,
connect as follows. It provides a general purpose I/O setup with a hard wired start / stop enable, thermistor input and a
selection between an analog speed reference or preset speed input.
9902 = 11 3-Wire Forward Reverse
Active input across terminal 1 & 2 will cause the
drive to run.
Closing terminal 3 will force operation at preset
speed 1 (parameter 1202) or function as a jog
command.
Terminal 4 will function as a motor thermistor trip
input as dened below.
Note:
When PTC motor thermistor is used, 1304 must set to Ptc-th mode. Otherwise digital input 3 will be used
as external trip input (digital level sensitive). When 1304 is set to
Ptc-th, drive will display code -Ptc if
thermistor value is larger than 2.5k ohm. The trip can only be reset if the thermistor value drops below 1.9k
ohm. Thermistor must be connected between terminal 1 (24V DC) and terminal 4 (2nd analog input). If 1304 is
set to other value, the input will be used as external trip trigger input and drive will display code
E-trp instead
if the input is open.
E-trp only happens when drive is enabled (running), however thermistor trip can happen
at any time.
