Operating Instructions
Cause
Select correct source for reference value.
For example, for speed setting via a multifunction
input, set at least one of parameters P475 or P492 to
"1 - analog input 1" (terminal X12.3) or "2 - analog
input 2" (terminal X12.4).
For P452 (terminal X12.3) and P562 (terminal X12.4),
select the correct signal to set the reference value
("1 - voltage" or "2 - current").
For P68 (Start clockwise) or P69 (Start anticlock-
wise), select the required digital input.
Check P418 (Minimum frequency).
Set digital input for the start command to the re-
quired evaluation ("0 - NPN" or "1 - PNP").
Check actual value P228 (internal reference frequen-
cy). Check voltage or current value at reference val-
ue input.
Switch on both enable inputs STOA and STOB.
Check control cable connections.
Carry out setup (again).
Long cables will reduce the torque.
V/f characteristic: Check start-up behavior (P620),
flux-formation (P780 and P781) and starting current
(P623).
Field-orientated control: Check start-up behavior
(flux-formation P780 and P781) and torque limit
(P730), reset to factory settings if necessary.
Via P412 set the controller to "1 - state machine" or
"2 - remote contacts".
Switch on both enable inputs STOA and STOB.
Check motor cables.
Exchange two motor phases (e.g. U and V) at the
frequency inverter terminals.
Connect terminals U, V and W of the frequency in-
verter to the corresponding terminals U, V and W of
the motor.
Check if P493 or P495 is set to "3 - Inverted". The
reference value will be inverted.
Check if for P68 (Start clockwise) and P69 (Start
anticlockwise) the required digital inputs are select-
ed.
Check the characteristic parameters if the reference
value is defined via MFI1 or MFI2 and "6 - voltage
characteristic" or "7 - current characteristic" is select-
ed.
Check if P493 or P495 is set to "2 - positive only". In
this case, the reference value can only be positive.
Factory setting: "1 - (+/- reference value)".
Check values for P420 (acceleration clockwise) and
P422 (acceleration anticlockwise). The value
0.00 Hz/s blocks the corresponding direction of rota-
tion.
