Select the input type to voltage for analog input AI1 or AI2 with parameters. Set the appro-
priate analog input unit to V (volt) in parameter group 12 Standard AI.

Select the excitation mode in parameter group 13 Standard AO.3
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
The Safe torque off function (page 347).
Note: Only 24 V DC can be used for STO. Only PNP input configuration can be used.
￭ Control cable connection procedure R1…R9
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur.
