Description:
Those parameters make it possible to configure the functions of the digital inputs, according to the listed range.
Some notes regarding the Digital Input functions are presented next.
„
Run/Stop: In order to assure the correct operation of this function, it is necessary to program P0224 and/
or P0227 in 1.
„
Local/Remote: When programmed, this function activates “Local” when 0 V is applied to the input, and
“Remote” when +24 V are applied. It is also necessary to program P0220=4 (DIx).
„
Speed/Torque: This function is valid for P0202=4 or 5 (Sensorless Vector Control or Vector with Encoder),
and “Speed” is selected with 0 V applied to the input, whereas “Torque” by applying 24 V.
When Torque is selected, the speed regulator parameters P0161 and P0162 become inactive
(*)
. Thus the Total
Reference becomes the Torque Regulator input. Refer to the figures 11.1 and 11.2 .
(*) The speed regulator of the PID type is converted into a P type, with proportional gain 1.00 and a null integral
gain.
When Speed is selected, the gains of the speed regulator become again defined by P0161 and P0162. In the
applications with torque control it is recommended to follow the method described at the parameter P0160.
