Recommendation:
The use of the vector control operating modes is recommended for synchronous motors.
Dependency:
Closed-loop speed or torque control (with encoder) cannot be selected if the encoder type is not entered (p0400).
Closed-loop speed or torque control can be selected if the closed-loop speed/torque control was selected as
operating mode (p0108.2).
Only operation with U/f characteristic is possible if the rated motor speed is not entered (p0311).
A reluctance motor (p0300 = 8) can only be operated in a U/f control mode (p1300 < 20), a synchronous-reluctance
motor (p0300 = 6, 6xx) only in closed-loop speed/torque control.
Sensorless control on separately excited synchronous motors is only possible with a VSM module (see p0150,
p0151).
For chassis power units with reduced line voltage (see r0212 bit 0), the drive can only be operated in a control mode
(p1300 = 20...23) and with the DC link voltage control activated.
Refer to: p0108, r0108, p0212, p0300, p0311, p0400, p1501
Notice:
Active slip compensation is required in the U/f control types with Eco mode (p1300 = 4, 7). The scaling of the slip
compensation (p1335) should be set so that the slip is completely compensated (generally 100%).
The Eco mode is only effective in steady-state operation and when the ramp-function generator is not bypassed. In
the case of analog setpoints, if required the tolerance for ramp-up and ramp-down should be actively increased for
the ramp-function generator using p1148 in order to reliably signal a steady-state condition.
Note:
The closed-loop torque control can only be changed over in operation (p1300 = 20, 21) by selecting the closed-loop
speed control (p1501). At the changeover, the setting of p1300 does not change. In this case, the actual state is
displayed in r1407, bit 2 and bit 3.
For the open-loop control modes p1300 = 5 and 6 (textile sector), slip compensation p1335, resonance damping
p1338, and the Imax frequency controller are switched off internally so that the output frequency can be set precisely.
The Imax voltage controller remains active.
For the open-loop control modes p1300 = 4 and 7 (Eco mode), the efficiency can be optimized by varying the voltage
(when the operating point is constant).
Separately excited synchronous motors can only be operated in modes p1300 = 20, 21 and 23 - or for diagnostic
purposes in modes p1300 = 0, 3 and 18. For I/f control (p1300 = 18), the current amplitude can be set using p1609.
Both for U/f as well as for I/f control only a small load may be applied to the separately excited synchronous motor
because the excitation current is not calculated as a function of the load.
During operation (pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing over
drive data sets.
p1300 is pre-assigned depending on r0108.2 and p0187.
