Table 6.18
- Signal definition of analog inputs Al1
(P235) and Al2 (P239)
Asan example, refertothefollowing situation:AI1 is setto
voltage input(0 to10V)– P235 = 0,AI1 = 5 V, P234 = 1.00
and P236 = -70 %. Thus:
The motor will run in reverse direction of rotation as
defined by the commands (negative value) - if this is
possible (P231 = 2), with a module reference equal to
0.2 or 20 % of the maximum output frequency (P134).
I.e., if P134 = 66.00 Hz, then the frequency reference is
equal to 13.2 Hz.
The following configurations are available for the version
“A2” of the control board:
When current signals are used, change the switch
position S1:3 and/or S1:4 to ON.
In the functions 2, 3 and 4 in P235 or P239, the analog
functionAIxleaves this function and operates as a digital
input NPN (active withlowlevel)or as a digital inputPNP
(active with highlevel) or as a digitalinputwith levelsTTL.
The inverter displays E24 when the signal AIx (P235 or
P239) has been configured as digital input and AIx is at
the same time an analog reference (P221/P222).
