P331
Switchover freq. PMSM
(Switchover frequency PMSM)
S P
1.0 ... 100.0 %
{ 15.0 }
Definition of the frequency up to which in operation without encoder the control method of a
PMSM (Permanent Magnet Synchronous Motor) is activated according to (P330). In this case,
100 % corresponds to the nominal motor frequency from (P201).

Hyst. Switchover PMSM
(Switchover frequency hysteresis PMSM)
S P
0.1 ... 25.0 %
{ 2.0 }
Difference between the switch-on and switch-off point in order to prevent oscillation on the
transition of operation without encoder into the control method specified in (P330) (and vice
versa).

P334
Encoder offset PMSM
(Encoder offset PMSM)
S
-0,500 ... 0,500 rev
{ 0,000 }
Evaluation of the zero track and the Sense signal is necessary for the operation of PMSM
(Permanent Magnet Synchronous Motors). The zero impulse is then used for
synchronisation of the rotor position. The offset between the zero pulse and the actual
"zero" rotor position is set in parameter (P334) "Encoder offset". If the Sense cable (+5 V
Sense and 0 V Sense) is not connected, there is no synchronisation to the zero pulse.
