ABB ACQ80-04 Series User Manual

DI5 as frequency input
See section Digital inputs DI1…DI6 (page 126) for which digital input can be used as a
frequency input in the drive. For setting the parameters for the digital frequency input, see
ACQ80-04 standard control program firmware manual (.3AXD50000170654 [English])
AI1 and AI2 as Pt100 sensor inputs (X1)
One, two or three Pt100 sensors for motor temperature measurement can be connected
between an analog input and output as shown below. Do not connect both ends of the cable
shields directly to ground, nor connect the capacitor at one end to the ground and another
end directly to ground.

DI5 as frequency input
See section Digital inputs DI1…DI6 on page 138 for which digital input can be used
as a frequency input in the drive.For setting the parameters for the digital frequency
input, see ACS560 standard control program firmware manual (3AXD50000044997
[English]).
AI1 and AI2 as Pt100 sensor inputs (X1)
One, two or three Pt100 sensors for motor temperature measurement can be
connected between an analog input and output as shown below. Do not connect both
ends of the cable shields directly to ground, nor connect the capacitor at one end to
the ground and another end directly to ground.
WARNING! As the inputs pictured above are not insulated according to IEC 60664, the
connection of the motor temperature sensor requires double or reinforced insulation
between motor live parts and the sensor. If the assembly does not fulfill the requirement, the I/O
board terminals must be protected against contact and must not be connected to other
equipment or the temperature sensor must be isolated from the I/O terminals.
Safe torque off (X4)
For the drive to start, both connections (+24 V DC to IN1 and +24 V DC to IN2) must
be closed. By default, the terminal block has jumpers to close the circuit. Remove the
jumpers before connecting an external Safe torque off circuitry to the drive. See
chapter Safe torque off function on page 167.
Note: Only 24 V DC can be used for STO. Only PNP input configuration can be used.
