Dependency: Closed-loop speed control can be selected if, as operating mode (refer to p0108), at least closed-loop speed control
was selected.
Closed-loop torque control can only be selected if, as operating mode, at least the closed-loop torque/force control
was selected.
Only operation with V/f characteristic is possible if the rated motor speed is not entered (p0311).
Closed-loop speed or torque control (with encoder) cannot be selected if the encoder type is not entered (p0400).
For vector drives (refer to p0107):
A synchronous motor can only be operated in a V/f control mode (p1300 < 20).
Refer to: r0108, p0300, p0311, p0400, p1501
Note: Closed-loop speed or torque control (with encoder) cannot be selected if the encoder type is not entered (p0400).
The closed-loop torque control can only be changed over in operation (p1300 = 20 or 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.
In the servo control mode the following applies:
Only p1300 = 20, 21, 23 can be set.
For closed-loop vector control, the following applies:
Closed-loop speed control can be selected if, as operating mode (p0108), at least closed-loop speed control was
selected.
Closed-loop torque control can be selected if, as operating mode, at least the closed-loop torque/force control was
selected.
Only operation with V/f characteristic is possible if the rated motor speed is not entered (p0311).
A synchronous motor can only be operated in a V/f control mode (p1300 < 20).
During operation (the pulses enabled) the open-loop/closed-loop control mode cannot be changed by changing-
over drive data sets.
