• The original configuration of the drive assumes positive logic
operation.
• Using a drive with a control system which has a different control logic
may cause unwanted starting of the motor.
• See section 4.4 for configuring the drive for negative logic, and connect
the common to 0V.

(*) : CAUTION :
If 16 is set to 4-20mA or 20-4 mA (with detection of signal break), and the value of
reference A2 is < 3mA, the drive switches to "CL". It is then impossible to
select reference A1. Simply set 16 = 4-.20 or 20.-4 (without break detection), then
clear the fault by pressing , before selecting reference A1.
