Recommendation: The use of the vector control operating modes is recommended for synchronous motors.
Dependency: If you are working with reduced supply voltages (p0212.0 = 1), only U/f control with independent voltage setpoint
(p1300 = 19) can be set as the operating mode.
p1300 = 15 (operation with braking resistor), can only be activated or deactivated in quick commissioning (p0010 =
1). This operating mode is only possible for chassis power units (DC/AC Motor Module).
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 motors, type p0300 = 14, operation with U/f control is only recommended for diagnostic purposes.
